1.1. Introduction

There is a lot of software freely available for Unix based systems, which
usually runs on NetBSD and other Unix-flavoured systems, too, sometimes with
some modifications. The NetBSD Packages Collection (pkgsrc) incorporates any
such changes necessary to make that software run, and makes the installation
(and de-installation) of the software package easy by means of a single
command.

Once the software has been built, it is manipulated with the pkg_* tools so
that installation and de-installation, printing of an inventory of all
installed packages and retrieval of one-line comments or more verbose
descriptions are all simple.

pkgsrc currently contains several thousand packages, including:

  * www/apache - The Apache web server

  * www/mozilla - The Mozilla web browser

  * meta-pkgs/gnome - The GNOME Desktop Environment

  * meta-pkgs/kde3 - The K Desktop Environment

...just to name a few.

pkgsrc has built-in support for handling varying dependencies, such as pthreads
and X11, and extended features such as IPv6 support on a range of platforms.

pkgsrc was derived from FreeBSD's ports system, and initially developed for
NetBSD only. Since then, pkgsrc has grown a lot, and now supports the following
platforms:

  * Darwin (Mac OS X)

  * DragonFlyBSD

  * FreeBSD

  * Microsoft Windows, via Interix

  * IRIX

  * Linux

  * NetBSD (of course)

  * Tru64 (Digital UNIX, OSF1)

  * OpenBSD

  * Solaris

1.2. Overview

This document is divided into two parts. The first, The pkgsrc user's guide,
describes how one can use one of the packages in the Package Collection, either
by installing a precompiled binary package, or by building one's own copy using
the NetBSD package system. The second part, The pkgsrc developer's guide,
explains how to prepare a package so it can be easily built by other NetBSD
users without knowing about the package's building details.

This document is available in various formats:

  * HTML

  * PDF

  * PS

  * TXT

1.3. Terminology

There has been a lot of talk about "ports", "packages", etc. so far. Here is a
description of all the terminology used within this document.

Package

    A set of files and building instructions that describe what's necessary to
    build a certain piece of software using pkgsrc. Packages are traditionally
    stored under /usr/pkgsrc.

The NetBSD package system

    This is the former name of "pkgsrc". It is part of the NetBSD operating
    system and can be bootstrapped to run on non-NetBSD operating systems as
    well. It handles building (compiling), installing, and removing of
    packages.

Distfile

    This term describes the file or files that are provided by the author of
    the piece of software to distribute his work. All the changes necessary to
    build on NetBSD are reflected in the corresponding package. Usually the
    distfile is in the form of a compressed tar-archive, but other types are
    possible, too. Distfiles are usually stored below /usr/pkgsrc/distfiles.

Port

    This is the term used by FreeBSD and OpenBSD people for what we call a
    package. In NetBSD terminology, "port" refers to a different architecture.

Precompiled/binary package

    A set of binaries built with pkgsrc from a distfile and stuffed together in
    a single .tgz file so it can be installed on machines of the same machine
    architecture without the need to recompile. Packages are usually generated
    in /usr/pkgsrc/packages; there is also an archive on ftp.NetBSD.org.

    Sometimes, this is referred to by the term "package" too, especially in the
    context of precompiled packages.

Program

    The piece of software to be installed which will be constructed from all
    the files in the Distfile by the actions defined in the corresponding
    package.

1.4. Typography

When giving examples for commands, shell prompts are used to show if the
command should/can be issued as root, or if "normal" user privileges are
sufficient. We use a # for root's shell prompt, and a % for users' shell
prompt, assuming they use the C-shell or tcsh.

Chapter 2. Where to get pkgsrc

Table of Contents

2.1. As tar file
2.2. Via SUP
2.3. Via CVS

There are three ways to get pkgsrc. Either as a tar file, via SUP, or via CVS.
All three ways are described here.

2.1. As tar file

To get pkgsrc going, you need to get the pkgsrc.tar.gz file from ftp.NetBSD.org
and unpack it into /usr/pkgsrc.

2.2. Via SUP

As an alternative to the tar file, you can get pkgsrc via the Software Update
Protocol, SUP. To do so, make sure your supfile has a line

release=pkgsrc

in it, see the examples in /usr/share/examples/supfiles, and that the /usr/
pkgsrc directory exists. Then, simply run sup -v /path/to/your/supfile.

2.3. Via CVS

To get pkgsrc via CVS, make sure you have "cvs" installed. To do an initial
(full) checkout of pkgsrc, do the following steps:

% setenv CVSROOT anoncvs@anoncvs.NetBSD.org:/cvsroot
% setenv CVS_RSH ssh
% cd /usr
% cvs checkout -P pkgsrc

This will create the pkgsrc directory in your /usr, and all the package source
will be stored under /usr/pkgsrc. To update pkgsrc after the initial checkout,
make sure you have CVS_RSH set as above, then do:

% cd /usr/pkgsrc
% cvs -q update -dP

Please also note that it is possible to have multiple copies of the pkgsrc
hierarchy in use at any one time - all work is done relatively within the
pkgsrc tree.

    3.2.2. FreeBSD
    3.2.3. Interix
    3.2.4. IRIX
    3.2.5. Linux
    3.2.6. OpenBSD
    3.2.7. Solaris

3.1. Bootstrapping pkgsrc

For operating systems other than NetBSD, we provide a bootstrap kit to build
the required tools to use pkgsrc on your platform. Besides support for native
NetBSD, pkgsrc and the bootstrap kit have support for the following operating
systems:

  * Darwin (Mac OS X)

  * DragonFlyBSD

  * FreeBSD

  * Interix (Windows 2000, XP, 2003)

  * IRIX

  * Linux

  * OpenBSD

  * Solaris

  * Tru64 (Digital UNIX/OSF1)

Support for other platforms is under development.

Installing the bootstrap kit should be as simple as:

# env CVS_RSH=ssh cvs -d anoncvs@anoncvs.NetBSD.org:/cvsroot checkout pkgsrc
# cd pkgsrc/bootstrap
# ./bootstrap

See Chapter 2, Where to get pkgsrc for other ways to get pkgsrc before
bootstrapping. The given bootstrap command will use the defaults of /usr/pkg
for the prefix where programs will be installed in, and /var/db/pkg for the
package database directory where pkgsrc will do its internal bookkeeping.
However, these can also be set using command-line arguments.

Binary packages for the pkgsrc tools and an initial set of packages is
available for supported platforms. An up-to-date list of these can be found on
www.pkgsrc.org.

3.2. Platform specific notes

Here are some platform-specific notes you should be aware of.

3.2.1. Darwin (Mac OS X)

Darwin 5.x and 6.x are supported. There are two methods of using pkgsrc on Mac
OS X, by using a disk image, or a UFS partition.

Before you start, you will need to download and install the Mac OS X Developer
Tools from Apple's Developer Connection. See http://developer.apple.com/macosx/
for details. Also, make sure you install X11 for Mac OS X and the X11 SDK from
http://www.apple.com/macosx/x11/download/ if you intend to build packages that
use the X11 Window System.

If you already have a UFS partition, or have a spare partition that you can
format as UFS, it is recommended to use that instead of the disk image. It'll
be somewhat faster and will mount automatically at boot time, where you must
manually mount a disk image.

Note

You cannot use a HFS+ file system for pkgsrc, because pkgsrc currently requires
the filesystem to be case-sensitive, and HFS+ is not.

3.2.1.1. Using a disk image

Create the disk image:

# cd pkgsrc/bootstrap
# ./ufsdiskimage create ~/Documents/NetBSD 512 # megabytes - season to taste
# ./ufsdiskimage mount ~/Documents/NetBSD
# sudo chown `id -u`:`id -g` /Volumes/NetBSD

That's it!

3.2.1.2. Using a UFS partition

By default, /usr will be on your root file system, normally HFS+. It is
possible to use the default prefix of /usr/pkg by symlinking /usr/pkg to a
directory on a UFS file system. Obviously, another symlink is required if you
want to place the package database directory outside the prefix. e.g.

# ./bootstrap --pkgdbdir /usr/pkg/pkgdb --pkgsrcdir /Volumes/ufs/pkgsrc

If you created your partitions at the time of installing Mac OS X and formatted
the target partition as UFS, it should automatically mount on /Volumes/<volume
name> when the machine boots. If you are (re)formatting a partition as UFS, you
need to ensure that the partition map correctly reflects "Apple_UFS" and not
"Apple_HFS".

The problem is that none of the disk tools will let you touch a disk that is
booted from. You can unmount the partition, but even if you newfs it, the
partition type will be incorrect and the automounter won't mount it. It can be
mounted manually, but it won't appear in Finder.

You'll need to boot off of the OS X Installation (User) CD. When the
Installation program starts, go up to the menu and select Disk Utility. Now,
you will be able to select the partition you want to be UFS, and Format it
Apple UFS. Quit the Disk Utility, quit the installer which will reboot your
machine. The new UFS file system will appear in Finder.

Be aware that the permissions on the new file system will be writable by root
only.

This note is as of 10.2 (Jaguar) and applies to earlier versions. Hopefully
Apple will fix Disk Utility in 10.3 (Panther).

3.2.2. FreeBSD

FreeBSD 4.7 and 5.0 have been tested and are supported, other versions may
work.

Care should be taken so that the tools that this kit installs do not conflict
with the FreeBSD userland tools. There are several steps:

 1. FreeBSD stores its ports pkg database in /var/db/pkg. It is therefore
    recommended that you choose a different location (e.g. /usr/pkgdb) by using
    the --pkgdbdir option to the bootstrap script.

 2. If you do not intend to use the FreeBSD ports tools, it's probably a good
    idea to move them out of the way to avoid confusion, e.g.

    # cd /usr/sbin
    # mv pkg_add pkg_add.orig
    # mv pkg_create pkg_create.orig
    # mv pkg_delete pkg_delete.orig
    # mv pkg_info pkg_info.orig

 3. An example /etc/mk.conf file will be placed in /etc/mk.conf.example file
    when you use the bootstrap script.

3.2.3. Interix

Interix is a POSIX compatible subsystem for the Windows NT kernel, providing a
Unix-like environment with a tighter kernel integration than available with
Cygwin. It is part of the Windows Services for Unix package, available for free
for any licensed copy of Windows 2000, XP (not including XP Home), or 2003. SFU
can be downloaded from http://www.microsoft.com/windows/sfu/.

Services for Unix 3.5, current as of this writing, has been tested. 3.0 or 3.1
may work, but are not officially supported. (The main difference in 3.0/3.1 is
lack of pthreads.)

3.2.3.1. When installing Interix/SFU

At an absolute minimum, the following packages must be installed from the
Windows Services for Unix 3.5 distribution in order to use pkgsrc:

  * Utilities -> Base Utilities

  * Interix GNU Components -> (all)

  * Remote Connectivity

  * Interix SDK

When using pkgsrc on Interix, DO NOT install the Utilities subcomponent "UNIX
Perl". That is Perl 5.6 without shared module support, installed to /usr/local,
and will only cause confusion. Instead, install Perl 5.8 from pkgsrc (or from a
binary package).

The Remote Connectivity subcomponent "Windows Remote Shell Service" does not
need to be installed, but Remote Connectivity itself should be installed in
order to have a working inetd.

Finally, during installation you may be asked whether to enable setuid behavior
for Interix programs, and whether to make pathnames default to case-sensitive.
Setuid should be enabled, and case-sensitivity MUST be enabled. (Without
case-sensitivity, a large number of packages including perl will not build.)

3.2.3.2. What to do if Interix/SFU is already installed

If SFU is already installed and you wish to alter these settings to work with
pkgsrc, note the following things.

  * To uninstall UNIX Perl, use Add/Remove Programs, select Microsoft Windows
    Services for UNIX, then click Change. In the installer, choose Add or
    Remove, then uncheck Utilities->UNIX Perl.

  * To enable case-sensitivity for the filesystem, run REGEDIT.EXE, and change
    the following registry key:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\kernel

    Set the DWORD value "obcaseinsensitive" to 0; then reboot.

  * To enable setuid binaries (optional), run REGEDIT.EXE, and change the
    following registry key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Services for UNIX

    Set the DWORD value "EnableSetuidBinaries" to 1; then reboot.

3.2.3.3. Important notes for using pkgsrc

The package imanager (either the pkgsrc "su" user, or the user running
"pkg_add") must be a member of the local Administrators group. Such a user must
also be used to run the bootstrap. This is slightly relaxed from the normal
pkgsrc requirement of "root".

The package manager should use a umask of 002. "make install" will
automatically complain if this is not the case. This ensures that directories
written in /var/db/pkg are Administrators-group writeable.

The popular Interix binary packages from http://www.interopsystems.com/ use an
older version of pkgsrc's pkg_* tools. Ideally, these should NOT be used in
conjunction with pkgsrc. If you choose to use them at the same time as the
pkgsrc packages, ensure that you use the proper pkg_* tools for each type of
binary package.

The TERM setting used for DOS-type console windows (including those invoked by
the csh and ksh startup shortcuts) is "interix". Most systems don't have a
termcap/terminfo entry for it, but the following .termcap entry provides
adequate emulation in most cases:

interix:kP=\E[S:kN=\E[T:kH=\E[U:dc@:DC@:tc=pcansi:

3.2.4. IRIX

You will need a working C compiler, either gcc or SGI's MIPS and MIPSpro
compiler (cc/c89). Please set the CC environment variable according to your
preference. If you do not have a license for the MIPSpro compiler suite, you
can download a gcc tardist file from http://freeware.sgi.com/.

Please note that you will need IRIX 6.5.17 or higher, as this is the earliest
version of IRIX providing support for if_indextoname(3), if_nametoindex(3),
etc.

At this point in time, pkgsrc only supports one ABI at a time. That is, you can
not switch between the old 32-bit ABI, the new 32-bit ABI and the 64-bit ABI.
If you start out using "abi=n32", that's what all your packages will be built
with.

Therefore, please make sure that you have no conflicting CFLAGS in your
environment or the /etc/mk.conf. Particularly, make sure that you do not try to
link n32 object files with lib64 or vice versa. Check your /etc/
compiler.defaults!

If you have the actual pkgsrc tree mounted via NFS from a different host,
please make sure to set WRKOBJDIR to a local directory, as it appears that IRIX
linker occasionally runs into issues when trying to link over a network mounted
filesystem.

The bootstrapping process should set all the right options for programs such as
imake(1), but you may want to set some options depending on your local setup.
Please see pkgsrc/mk/defaults/mk.conf and, of course, your compiler's man pages
for details.

If you are using SGI's MIPSPro compiler, please set

PKGSRC_COMPILER=mipspro

in /etc/mk.conf. Otherwise, pkgsrc will assume you are using gcc and may end up
passing invalid flags to the compiler. Note that bootstrap should create an
appropriate mk.conf.example by default.

If you have both the MIPSPro compiler chain installed as well as gcc, but want
to make sure that MIPRPro is used, please set your PATH to not include the
location of gcc (often /usr/freeware/bin), and (important) pass the
'--preserve-path' flag.

3.2.5. Linux

Some versions of Linux (for example Debian GNU/Linux) need either libtermcap or
libcurses (libncurses). Installing the distributions libncurses-dev package (or
equivalent) should fix the problem.

pkgsrc supports both gcc (GNU Compiler Collection) and icc (Intel C++
Compiler). gcc is the default. icc 8.0 and 8.1 on i386 have been tested.

To bootstrap using icc, assuming the default icc installation directory:

env CC=/opt/intel_cc_80/bin/icc LDFLAGS=-static-libcxa \
                ac_cv___attribute__=yes ./bootstrap

Note

icc 8.1 needs the `-i-static' argument instead of -static-libcxa.

icc supports __attribute__, but the GNU configure test uses a nested function,
which icc does not support. #undef'ing __attribute__ has the unfortunate
side-effect of breaking many of the Linux header files, which cannot be
compiled properly without __attribute__. The test must be overridden so that
__attribute__ is assumed supported by the compiler.

After bootstrapping, you should set PKGSRC_COMPILER in /etc/mk.conf:

PKGSRC_COMPILER=icc

The default installation directory for icc is /opt/intel_cc_80, which is also
the pkgsrc default. If you have installed it into a different directory, set
ICCBASE in /etc/mk.conf:

ICCBASE=/opt/icc

pkgsrc uses the static linking method of the runtime libraries provided by icc,
so binaries can be run on other systems which do not have the shared libraries
installed.

Libtool, however, extracts a list of libraries from the ld(1) command run when
linking a C++ shared library and records it, throwing away the -Bstatic and
-Bdynamic options interspersed between the libraries. This means that
libtool-linked C++ shared libraries will have a runtime dependency on the icc
libraries until this is fixed in libtool.

3.2.6. OpenBSD

OpenBSD 3.0 and 3.2 are tested and supported.

Care should be taken so that the tools that this kit installs do not conflict
with the OpenBSD userland tools. There are several steps:

 1. OpenBSD stores its ports pkg database in /var/db/pkg. It is therefore
    recommended that you choose a different location (e.g. /usr/pkgdb) by using
    the --pkgdbdir option to the bootstrap script.

 2. If you do not intend to use the OpenBSD ports tools, it's probably a good
    idea to move them out of the way to avoid confusion, e.g.

    # cd /usr/sbin
    # mv pkg_add pkg_add.orig
    # mv pkg_create pkg_create.orig
    # mv pkg_delete pkg_delete.orig
    # mv pkg_info pkg_info.orig

 3. An example /etc/mk.conf file will be placed in /etc/mk.conf.example file
    when you use the bootstrap script. OpenBSD's make program uses /etc/mk.conf
    as well. You can work around this by enclosing all the pkgsrc specific
    parts of the file with:

    .ifdef BSD_PKG_MK
    # pkgsrc stuff, e.g. insert defaults/mk.conf or similar here
    .else
    # OpenBSD stuff
    .endif


3.2.7. Solaris

Solaris 2.6 through 9 are supported on both x86 and sparc. You will need a
working C compiler. Both gcc 2.95.3 and Sun WorkShop 5 have been tested.

The following packages are required on Solaris 8 for the bootstrap process and
to build packages.

  * SUNWsprot

  * SUNWarc

  * SUNWbtool

  * SUNWtoo

  * SUNWlibm

Please note the use of GNU binutils on Solaris is not supported.

3.2.7.1. If you are using gcc

It makes life much simpler if you only use the same gcc consistently for
building all packages.

It is recommended that an external gcc be used only for bootstrapping, then
either build gcc from lang/gcc or install a binary gcc package, then remove gcc
used during bootstrapping.

Binary packages of gcc can be found through http://www.sun.com/bigadmin/common/
freewareSearch.html.

3.2.7.2. If you are using Sun WorkShop

You will need at least the following packages installed (from WorkShop 5.0)

  * SPROcc - Sun WorkShop Compiler C 5.0

  * SPROcpl - Sun WorkShop Compiler C++ 5.0

  * SPROild - Sun WorkShop Incremental Linker

  * SPROlang - Sun WorkShop Compilers common components

You should set CC, CXX and optionally, CPP in /etc/mk.conf, eg.

CC=     cc
CXX=    CC
CPP=    /usr/ccs/lib/cpp

You may also want to build 64-bit binaries, eg.

CFLAGS= -xtarget=ultra -xarch=v9

Whichever compiler you use, please ensure the compiler tools and your $prefix
are in your PATH. This includes /usr/ccs/{bin,lib} and eg. /usr/pkg/{bin,sbin}.

4.1. Working with binary packages

This section describes how to find, retrieve and install a precompiled binary
package that someone else already prepared for your type of machine.

4.1.1. Where to get binary packages

Precompiled packages are stored on ftp.NetBSD.org and its mirrors in the
directory /pub/NetBSD/packages/<OSVERSION>/<ARCH>/ for anonymous FTP access.
OSVERSION is the NetBSD version (uname -r), ARCH is the architecture (uname -p
). In that directory, there is a subdirectory for each category plus a
subdirectory All which includes the actual binaries in .tgz files. The category
subdirectories use symbolic links to those files (this is the same directory
layout as in /usr/pkgsrc/packages).

This same directory layout applies for CDROM distributions, only that the
directory may be rooted somewhere else, probably somewhere below /cdrom. Please
consult your CDROMs documentation for the exact location.

4.1.2. How to use binary packages

If you have the files on a CDROM or downloaded them to your hard disk, you can
install them with the following command (be sure to su to root first):

# pkg_add /path/to/package.tgz

If you have FTP access and you don't want to download the packages via FTP
prior to installation, you can do this automatically by giving pkg_add an FTP
URL:

# pkg_add ftp://ftp.NetBSD.org/pub/NetBSD/packages/<OSVERSION>/<ARCH>/All/package.tgz

Note that any prerequisite packages needed to run the package in question will
be installed, too, assuming they are present where you install from.

To save some typing, you can set the PKG_PATH environment variable to a
semicolon separated list of paths (including remote URLs); trailing slashes are
not allowed.

Additionally to the All directory there exists a vulnerable directory to which
binary packages with known vulnerabilities are moved, since removing them could
cause missing dependencies. To use these packages, add the vulnerable directory
to your PKG_PATH. However, you should run security/audit-packages regularly,
and especially after installing new packages, and verify that the
vulnerabilities are acceptable for your configuration. An example PKG_PATH
would be: ftp://ftp.NetBSD.org/pub/NetBSD/packages/<OSVERSION>/<ARCH>/All;ftp:/
/ftp.NetBSD.org/pub/NetBSD/packages/<OSVERSION>/<ARCH>/vulnerable Please note
that semicolon (';') is a shell meta-character, so you'll probably have to
quote it.

After you've installed packages, be sure to have /usr/pkg/bin and /usr/pkg/sbin
in your PATH so you can actually start the just installed program.

4.1.3. A word of warning

Please pay very careful attention to the warnings expressed in the pkg_add(1)
manual page about the inherent dangers of installing binary packages which you
did not create yourself, and the security holes that can be introduced onto
your system by indiscriminate adding of such files.

4.2. Building packages from source

This assumes that the package is already in pkgsrc. If it is not, see Part II,
"The pkgsrc developer's guide" for instructions how to create your own
packages.

4.2.1. Requirements

To build packages from source on a NetBSD system the "comp" and the "text"
distribution sets must be installed. If you want to build X11 related packages
the "xbase" and "xcomp" distribution sets are required, too.

4.2.2. Fetching distfiles

The first step for building a package is downloading the distfiles (i.e. the
unmodified source). If they have not yet been downloaded, pkgsrc will fetch
them automatically.

You can overwrite some of the major distribution sites to fit to sites that are
close to your own. Have a look at pkgsrc/mk/defaults/mk.conf to find some
examples ? in particular, look for the MASTER_SORT, MASTER_SORT_REGEX and
INET_COUNTRY definitions. This may save some of your bandwidth and time.

You can change these settings either in your shell's environment, or, if you
want to keep the settings, by editing the /etc/mk.conf file, and adding the
definitions there.

If you don't have a permanent Internet connection and you want to know which
files to download, make fetch-list will tell you what you'll need. Put these
distfiles into /usr/pkgsrc/distfiles.

4.2.3. How to build and install

Assuming that the distfile has been fetched (see previous section), become root
and change into the relevant directory and running make. For example, type

% cd misc/figlet
% make

at the shell prompt to build the various components of the package, and

# make install

to install the various components into the correct places on your system.
Installing the package on your system requires you to be root. However, pkgsrc
has a just-in-time-su feature, which allows you to only become root for the
actual installation step

Taking the figlet utility as an example, we can install it on our system by
building as shown in Appendix B, Build logs.

The program is installed under the default root of the packages tree - /usr/
pkg. Should this not conform to your tastes, set the LOCALBASE variable in your
environment, and it will use that value as the root of your packages tree. So,
to use /usr/local, set LOCALBASE=/usr/local in your environment. Please note
that you should use a directory which is dedicated to packages and not shared
with other programs (ie, do not try and use LOCALBASE=/usr). Also, you should
not try to add any of your own files or directories (such as src/, obj/, or
pkgsrc/) below the LOCALBASE tree. This is to prevent possible conflicts
between programs and other files installed by the package system and whatever
else may have been installed there.

Some packages look in /etc/mk.conf to alter some configuration options at build
time. Have a look at pkgsrc/mk/defaults/mk.conf to get an overview of what will
be set there by default. Environment variables such as LOCALBASE can be set in
/etc/mk.conf to save having to remember to set them each time you want to use
pkgsrc.

Occasionally, people want to "look under the covers" to see what is going on
when a package is building or being installed. This may be for debugging
purposes, or out of simple curiosity. A number of utility values have been
added to help with this.

 1. If you invoke the make(1) command with PKG_DEBUG_LEVEL=2, then a huge
    amount of information will be displayed. For example,

    make patch PKG_DEBUG_LEVEL=2

    will show all the commands that are invoked, up to and including the
    "patch" stage.

 2. If you want to know the value of a certain make(1) definition, then the
    VARNAME definition should be used, in conjunction with the show-var target.
    e.g. to show the expansion of the make(1) variable LOCALBASE:

    % make show-var VARNAME=LOCALBASE
    /usr/pkg
    %



If you want to install a binary package that you've either created yourself
(see next section), that you put into pkgsrc/packages manually or that is
located on a remote FTP server, you can use the "bin-install" target. This
target will install a binary package - if available - via pkg_add(1), else do a
make package. The list of remote FTP sites searched is kept in the variable
BINPKG_SITES, which defaults to ftp.NetBSD.org. Any flags that should be added
to pkg_add(1) can be put into BIN_INSTALL_FLAGS. See pkgsrc/mk/defaults/mk.conf
for more details.

A final word of warning: If you setup a system that has a non-standard setting
for LOCALBASE, be sure to set that before any packages are installed, as you
can not use several directories for the same purpose. Doing so will result in
pkgsrc not being able to properly detect your installed packages, and fail
miserably. Note also that precompiled binary packages are usually built with
the default LOCALBASE of /usr/pkg, and that you should not install any if you
use a non-standard LOCALBASE.

4.2.4. Selecting the compiler

By default, pkgsrc will use GCC to build packages. This may be overridden by
setting the following variables in /etc/mk.conf:

PKGSRC_COMPILER:

    This is a list of values specifying the chain of compilers to invoke when
    building packages. Valid values are:

      * distcc: distributed C/C++ (chainable)

      * ccache: compiler cache (chainable)

      * gcc: GNU C/C++ Compiler

      * mipspro: Silicon Graphics, Inc. MIPSpro (n32/n64)

      * mipspro: Silicon Graphics, Inc. MIPSpro (o32)

      * sunpro: Microsystems, Inc. WorkShip/Forte/Sun ONE Studio

    The default is "gcc". You can use ccache and/or distcc with an appropriate
    PKGSRC_COMPILER setting, e.g. "ccache gcc". This variable should always be
    terminated with a value for a real compiler.

GCC_REQD:

    This specifies the minimum version of GCC to use when building packages. If
    the system GCC doesn't satisfy this requirement, then pkgsrc will build and
    install one of the GCC packages to use instead.

5.1. Building a single binary package

Once you have built and installed a package, you can create a binary package
which can be installed on another system with pkg_add(1) This saves having to
build the same package on a group of hosts and wasting CPU time. It also
provides a simple means for others to install your package, should you
distribute it.

To create a binary package, change into the appropriate directory in pkgsrc,
and run make package:

# cd misc/figlet
# make package

This will build and install your package (if not already done), and then build
a binary package from what was installed. You can then use the pkg_* tools to
manipulate it. Binary packages are created by default in /usr/pkgsrc/packages,
in the form of a gzipped tar file. See Section B.2, "Packaging figlet" for a
continuation of the above misc/figlet example.

See Chapter 16, Submitting and Committing for information on how to submit such
a binary package.

5.2. Settings for creation of binary packages

See Section 13.3, "Other helpful targets".

5.3. Doing a bulk build of all packages

If you want to get a full set of precompiled binary packages, this section
describes how to get them. Beware that the bulk build will remove all currently
installed packages from your system! Having an FTP server configured either on
the machine doing the bulk builds or on a nearby NFS server can help to make
the packages available to everyone. See ftpd(8) for more information. If you
use a remote NFS server's storage, be sure to not actually compile on NFS
storage, as this slows things down a lot.

5.3.1. Configuration

5.3.1.1. /etc/mk.conf

You may want to set variables in /etc/mk.conf. Look at pkgsrc/mk/defaults/
mk.conf for details of the default settings. You will want to ensure that
ACCEPTABLE_LICENSES meet your local policy. As used in this example,
_ACCEPTABLE=yes accepts all licenses.

PACKAGES?=      ${_PKGSRCDIR}/packages/${MACHINE_ARCH}
WRKOBJDIR?=     /usr/tmp/pkgsrc   # build here instead of in pkgsrc
BSDSRCDIR=      /usr/src
BSDXSRCDIR=     /usr/xsrc         # for x11/xservers
OBJHOSTNAME?=   yes               # use work.`hostname`
FAILOVER_FETCH= yes               # insist on the correct checksum
PKG_DEVELOPER?= yes
_ACCEPTABLE=    yes

5.3.1.2. build.conf

In pkgsrc/mk/bulk, copy build.conf-example to build.conf and edit it, following
the comments in that file. This is the config file that determines where log
files are generated after the build, where to mail the build report to, where
your pkgsrc tree is located and the user to which user to su(8) to do a cvs
update.

5.3.1.3.  pre-build.local

It is possible to configure the bulk build to perform certain site specific
tasks at the end of the pre-build stage. If the file pre-build.local exists in
/usr/pkgsrc/mk/bulk, it will be executed (as a sh(1) script) at the end of the
usual pre-build stage. An example use of pre-build.local is to have the line:

# echo "I do not have enough disk space to build this pig." \
    > pkgsrc/misc/openoffice/$BROKENF

to prevent the system from trying to build a particular package which requires
nearly 3 GB of disk space.

5.3.2. Other environmental considerations

As /usr/pkg will be completely deleted at the start of bulk builds, make sure
your login shell is placed somewhere else. Either drop it into /usr/local/bin
(and adjust your login shell in the passwd file), or (re-)install it via
pkg_add(1) from /etc/rc.local, so you can login after a reboot (remember that
your current process won't die if the package is removed, you just can't start
any new instances of the shell any more). Also, if you use NetBSD earlier than
1.5, or you still want to use the pkgsrc version of ssh for some reason, be
sure to install ssh before starting it from rc.local:

( cd /usr/pkgsrc/security/ssh ; make bulk-install )
if [ -f /usr/pkg/etc/rc.d/sshd ]; then
    /usr/pkg/etc/rc.d/sshd
fi

Not doing so will result in you being not able to log in via ssh after the bulk
build is finished or if the machine gets rebooted or crashes. You have been
warned! :)

5.3.3. Operation

Make sure you don't need any of the packages still installed.

Warning

During the bulk build, all packages will be removed!

Be sure to remove all other things that might interfere with builds, like some
libs installed in /usr/local, etc. then become root and type:

# cd /usr/pkgsrc
# sh mk/bulk/build

If for some reason your last build didn't complete (power failure, system
panic, ...), you can continue it by running:

# sh mk/bulk/build restart

At the end of the bulk build, you will get a summary via mail, and find build
logs in the directory specified by FTP in the build.conf file.

5.3.4. What it does

The bulk builds consist of three steps:

1. pre-build

    The script updates your pkgsrc tree via (anon)cvs, then cleans out any
    broken distfiles, and removes all packages installed.

2. the bulk build

    This is basically "make bulk-package" with an optimised order in which
    packages will be built. Packages that don't require other packages will be
    built first, and packages with many dependencies will be built later.

3. post-build

    Generates a report that's placed in the directory specified in the
    build.conf file named broken.html, a short version of that report will also
    be mailed to the build's admin.

During the build, a list of broken packages will be compiled in /usr/pkgsrc
/.broken (or .../.broken.${MACHINE} if OBJMACHINE is set), individual build
logs of broken builds can be found in the package's directory. These files are
used by the bulk-targets to mark broken builds to not waste time trying to
rebuild them, and they can be used to debug these broken package builds later.

5.3.5. Disk space requirements

Currently, roughly the following requirements are valid for NetBSD 2.0/i386:

  * 10 GB - distfiles (NFS ok)

  * 8 GB - full set of all binaries (NFS ok)

  * 5 GB - temp space for compiling (local disk recommended)

Note that all pkgs will be de-installed as soon as they are turned into a
binary package, and that sources are removed, so there is no excessively huge
demand to disk space. Afterwards, if the package is needed again, it will be
installed via pkg_add(1) instead of building again, so there are no cycles
wasted by recompiling.

5.3.6. Setting up a sandbox for chroot'ed builds

If you don't want all the packages nuked from a machine (rendering it useless
for anything but pkg compiling), there is the possibility of doing the package
bulk build inside a chroot environment.

The first step is to set up a chroot sandbox, e.g. /usr/sandbox. This can be
done by using null mounts, or manually.

There is a shell script called pkgsrc/mk/bulk/mksandbox which will set up the
sandbox environment using null mounts. It will also create a script called
sandbox in the root of the sandbox environment, which will allow the null
mounts to be activated using the sandbox mount command and deactivated using
the sandbox umount command.

To set up a sandbox environment by hand, after extracting all the sets from a
NetBSD installation or doing a make distribution DESTDIR=/usr/sandbox in /usr/
src/etc, be sure the following items are present and properly configured:

 1. Kernel

    # cp /netbsd /usr/sandbox

 2. /dev/*

    # cd /usr/sandbox/dev ; sh MAKEDEV all

 3. /etc/resolv.conf (for security/smtpd and mail):

    # cp /etc/resolv.conf /usr/sandbox/etc

 4. Working(!) mail config (hostname, sendmail.cf):

    # cp /etc/mail/sendmail.cf /usr/sandbox/etc/mail

 5. /etc/localtime (for security/smtpd):

    # ln -sf /usr/share/zoneinfo/UTC /usr/sandbox/etc/localtime

 6. /usr/src (system sources, for sysutils/aperture, net/ppp-mppe):

    # ln -s ../disk1/cvs .
    # ln -s cvs/src-2.0 src

 7. Create /var/db/pkg (not part of default install):

    # mkdir /usr/sandbox/var/db/pkg

 8. Create /usr/pkg (not part of default install):

    # mkdir /usr/sandbox/usr/pkg

 9. Checkout pkgsrc via cvs into /usr/sandbox/usr/pkgsrc:

    # cd /usr/sandbox/usr
    # cvs -d anoncvs@anoncvs.NetBSD.org:/cvsroot checkout -d -P pkgsrc

    Do not mount/link this to the copy of your pkgsrc tree you do development
    in, as this will likely cause problems!

10. Make /usr/sandbox/usr/pkgsrc/packages and .../distfiles point somewhere
    appropriate. NFS- and/or nullfs-mounts may come in handy!

11. Edit /etc/mk.conf, see Section 5.3.1.1, "/etc/mk.conf".

12. Adjust mk/bulk/build.conf to suit your needs.

13. If you have set CVS_USER in build.conf, make sure that account exists and
    can do a cvs ${CVS_FLAGS} update properly!

When the chroot sandbox is setup, you can start the build with the following
steps:

# cd /usr/sandbox/usr/pkgsrc
# sh mk/bulk/do-sandbox-build

This will just jump inside the sandbox and start building. At the end of the
build, mail will be sent with the results of the build. Created binary pkgs
will be in /usr/sandbox/usr/pkgsrc/packages (wherever that points/mounts to/
from).

5.3.7. Building a partial set of packages

In addition to building a complete set of all packages in pkgsrc, the pkgsrc/mk
/bulk/build script may be used to build a subset of the packages contained in
pkgsrc. By setting defining SPECIFIC_PKGS in /etc/mk.conf, the variables

  * SITE_SPECIFIC_PKGS

  * HOST_SPECIFIC_PKGS

  * GROUP_SPECIFIC_PKGS

  * USER_SPECIFIC_PKGS

will define the set of packages which should be built. The bulk build code will
also include any packages which are needed as dependencies for the explicitly
listed packages.

One use of this is to do a bulk build with SPECIFIC_PKGS in a chroot sandbox
periodically to have a complete set of the binary packages needed for your site
available without the overhead of building extra packages that are not needed.

5.3.8. Uploading results of a bulk build

This section describes how pkgsrc developers can upload binary pkgs built by
bulk builds to ftp.NetBSD.org.

If you would like to automatically create checksum files for the binary
packages you intend to upload, remember to set MKSUMS=yes in your mk/bulk/
build.conf.

If you would like to PGP sign the checksum files (highly recommended!),
remember to set SIGN_AS=username@NetBSD.org in your mk/bulk/build.conf. This
will prompt you for your GPG password to sign the files before uploading
everything.

Then, make sure that you have RSYNC_DST set properly in your mk/bulk/build.conf
file, i.e. adjust it to something like one of the following:

RSYNC_DST=$CVS_USER@ftp.NetBSD.org:/pub/NetBSD/packages/pkgsrc-200xQy/NetBSD-a.b.c/arch/upload

Please use appropviate values for "pkgsrc-200xQy", "NetBSD-a.b.c" and "arch"
here. If your login on ftp.NetBSD.org is different from CVS_USER, write your
login directly into the variable, e.g. my local account is "feyrer", but for my
login "hubertf", I use:

RSYNC_DST=hubertf@ftp.NetBSD.org:/pub/NetBSD/packages/pkgsrc-200xQy/NetBSD-a.b.c/arch/upload

A separate upload directory is used here to allow "closing" the directory
during upload. To do so, run the following command on ftp.NetBSD.org next:

nbftp% mkdir -p -m 750 /pub/NetBSD/packages/pkgsrc-200xQy/NetBSD-a.b.c/arch/upload

Please note that /pub/NetBSD/packages is only appropriate for packages for the
NetBSD operating system. Binary packages for other operating systems should go
into /pub/pkgsrc.

Before uploading the binary pkgs, ssh authentication needs to be set up. This
example shows how to setup temporary keys for the root account inside the
sandbox (assuming that no keys should be present there usually):

# chroot /usr/sandbox
chroot-# rm $HOME/.ssh/id-dsa*
chroot-# ssh-keygen -t dsa
chroot-# cat $HOME/.ssh/id-dsa.pub

Now take the output of id-dsa.pub and append it to your ~/.ssh/authorized_keys
file on ftp.NetBSD.org. You can remove the key after the upload is done!

Next, test if your ssh connection really works:

chroot-# ssh ftp.NetBSD.org date

Use "-l yourNetBSDlogin" here as appropriate!

Now after all this works, you can exit the sandbox and start the upload:

chroot-# exit
# cd /usr/sandbox/usr/pkgsrc
# sh mk/bulk/do-sandbox-upload

The upload process may take quite some time. Use ls(1) or du(1) on the FTP
server to monitor progress of the upload. The upload script will take care of
not uploading restricted packages and putting vulnerable packages into the
vulnerable subdirectory.

After the upload has ended, first thing is to revoke ssh access:

nbftp% vi ~/.ssh/authorized_keys
Gdd:x!

Use whatever is needed to remove the key you've entered before! Last, move the
uploaded packages out of the upload directory to have them accessible to
everyone:

nbftp% cd /pub/NetBSD/packages/pkgsrc-200xQy/NetBSD-a.b.c/arch
nbftp% mv upload/* .
nbftp% rmdir upload
nbftp% chmod 755 .

5.4. Creating a multiple CD-ROM packages collection

After your pkgsrc bulk-build has completed, you may wish to create a CD-ROM set
of the resulting binary packages to assist in installing packages on other
machines. The pkgtools/cdpack package provides a simple tool for creating the
ISO 9660 images. cdpack arranges the packages on the CD-ROMs in a way that
keeps all the dependencies for given package on the same CD as that package.

5.4.1. Example of cdpack

Complete documentation for cdpack is found in the cdpack(1) manpage. The
following short example assumes that the binary packages are left in /usr/
pkgsrc/packages/All and that sufficient disk space exists in /u2 to hold the
ISO 9660 images.

# mkdir /u2/images
# pkg_add /usr/pkgsrc/packages/All/cdpack
# cdpack /usr/pkgsrc/packages/All /u2/images

If you wish to include a common set of files (COPYRIGHT, README, etc.) on each
CD in the collection, then you need to create a directory which contains these
files. e.g.

# mkdir /tmp/common
# echo "This is a README" > /tmp/common/README
# echo "Another file" > /tmp/common/COPYING
# mkdir /tmp/common/bin
# echo "#!/bin/sh" > /tmp/common/bin/myscript
# echo "echo Hello world" >> /tmp/common/bin/myscript
# chmod 755 /tmp/common/bin/myscript

Now create the images:

# cdpack -x /tmp/common /usr/pkgsrc/packages/All /u2/images

Each image will contain README, COPYING, and bin/myscript in their root
directories.

6.2. Where's the pkgviews documentation?

Pkgviews is tightly integrated with buildlink. You can find a pkgviews User's
guide in pkgsrc/mk/buildlink3/PKGVIEWS_UG.

6.3. Utilities for package management (pkgtools)

The pkgsrc/pkgtools directory pkgtools contains a number of useful utilities
for both users and developers of pkgsrc. This section attempts only to make the
reader aware of the utilities and when they might be useful, and not to
duplicate the documentation that comes with each package.

Utilities used by pkgsrc (automatically installed when needed):

  * pkgtools/x11-links: Symlinks for use by buildlink.

OS tool augmentation (automatically installed when needed):

  * pkgtools/digest: Calculates various kinds of checksums (including SHA1).

  * pkgtools/libnbcompat: Compatibility library for pkgsrc tools.

  * pkgtools/mtree: Installed on non-BSD systems due to lack of native mtree.

  * pkgtools/pkg_install: Up-to-date replacement for /usr/sbin/pkg_install, or
    for use on operating systems where pkg_install is not present.

Utilities used by pkgsrc (not automatically installed):

  * pkgtools/pkg_tarup: Create a binary package from an already-installed
    package. Used by make replace to save the old package.

  * pkgtools/dfdisk: Adds extra functionality to pkgsrc, allowing it to fetch
    distfiles from multiple locations. It currently supports the following
    methods: multiple CD-ROMs and network FTP/HTTP connections.

  * pkgtools/xpkgwedge: Put X11 packages someplace else (enabled by default).

  * devel/cpuflags: Determine the best compiler flags to optimise code for your
    current CPU and compiler.

Utilities for keeping track of installed packages, being up to date, etc:

  * pkgtools/pkg_chk: Reports on packages whose installed versions do not match
    the latest pkgsrc entries.

  * pkgtools/pkgdep: Makes dependency graphs of packages, to aid in choosing a
    strategy for updating.

  * pkgtools/pkgdepgraph: Makes graphs from the output of pkgtools/pkgdep (uses
    graphviz).

  * pkgtools/pkglint: The pkglint(1) program checks a pkgsrc entry for errors,
    lintpkgsrc(1) does various checks on the complete pkgsrc system.

  * pkgtools/pkgsurvey: Report what packages you have installed.

Utilities for people maintaining or creating individual packages:

  * pkgtools/pkgdiff: Automate making and maintaining patches for a package
    (includes pkgdiff, pkgvi, mkpatches, etc.).

  * pkgtools/rpm2pkg, pkgtools/url2pkg: Aids in converting to pkgsrc.

  * pkgtools/gensolpkg: Convert pkgsrc to a Solaris package.

Utilities for people maintaining pkgsrc (or more obscure pkg utilities)

  * pkgtools/pkgconflict: Find packages that conflict but aren't marked as
    such.

  * pkgtools/pkg_comp: Build packages in a chrooted area.

  * pkgtools/libkver: Spoof kernel version for chrooted cross builds.

6.4. How to use pkgsrc as non-root

If you want to use pkgsrc as non-root user, you can set some variables to make
pkgsrc work under these conditions. At the very least, you need to set
UNPRIVILEGED to "yes"; this will turn on unprivileged mode and set multiple
related variables to allow installation of packages as non-root.

In case the defaults are not enough, you may want to tune some other variables
used. For example, if the automatic user/group detection leads to incorrect
values (or not the ones you would like to use), you can change them by setting
UNPRIVILEGED_USER and UNPRIVILEGED_GROUP respectively.

As regards bootstrapping, please note that the bootstrap script will ease
non-root configuration when given the "--ignore-user-check" flag, as it will
choose and use multiple default directories under ~/pkg as the installation
targets. These directories can be overriden by the "--prefix" flag provided by
the script, as well as some others that allow finer tuning of the tree layout.

6.5. How to resume transfers when fetching distfiles?

By default resuming transfers in pkgsrc is disabled, but you can enable this
feature by adding the option PKG_RESUME_TRANSFERS=YES into /etc/mk.conf. If,
during a fetch step, an incomplete distfile is found, pkgsrc will try to resume
it.

You can also use a different program than the default ftp(1) by changing the
FETCH_CMD variable. Don't forget to set FETCH_RESUME_ARGS and FETCH_OUTPUT_ARGS
if you are not using default values.

For example, if you want to use wget to resume downloads, you'll have to use
something like:

FETCH_CMD=wget
FETCH_BEFORE_ARGS=--passive-ftp
FETCH_RESUME_ARGS=-c
FETCH_OUTPUT_ARGS=-O

6.6. How can I install/use XFree86 from pkgsrc?

If you want to use XFree86 from pkgsrc instead of your system's own X11 (/usr/
X11R6, /usr/openwin, ...), you will have to add the following line into /etc/
mk.conf:

X11_TYPE=XFree86

6.7. How can I install/use X.org from pkgsrc?

If you want to use X.org from pkgsrc instead of your system's own X11 (/usr/
X11R6, /usr/openwin, ...) you will have to add the following line into /etc/
mk.conf:

X11_TYPE=xorg

6.8. How to fetch files from behind a firewall

If you are sitting behind a firewall which does not allow direct connections to
Internet hosts (i.e. non-NAT), you may specify the relevant proxy hosts. This
is done using an environment variable in the form of a URL e.g. in Amdahl, the
machine "orpheus.amdahl.com" is one of the firewalls, and it uses port 80 as
the proxy port number. So the proxy environment variables are:

ftp_proxy=ftp://orpheus.amdahl.com:80/
http_proxy=http://orpheus.amdahl.com:80/

6.9. How do I tell make fetch to do passive FTP?

This depends on which utility is used to retrieve distfiles. From bsd.pkg.mk,
FETCH_CMD is assigned the first available command from the following list:

  * ${LOCALBASE}/bin/ftp

  * /usr/bin/ftp

On a default NetBSD installation, this will be /usr/bin/ftp, which
automatically tries passive connections first, and falls back to active
connections if the server refuses to do passive. For the other tools, add the
following to your /etc/mk.conf file: PASSIVE_FETCH=1.

Having that option present will prevent /usr/bin/ftp from falling back to
active transfers.

6.10. How to fetch all distfiles at once

You would like to download all the distfiles in a single batch from work or
university, where you can't run a make fetch. There is an archive of distfiles
on ftp.NetBSD.org, but downloading the entire directory may not be appropriate.

The answer here is to do a make fetch-list in /usr/pkgsrc or one of it's
subdirectories, carry the resulting list to your machine at work/school and use
it there. If you don't have a NetBSD-compatible ftp(1) (like lukemftp) at work,
don't forget to set FETCH_CMD to something that fetches a URL:

At home:

% cd /usr/pkgsrc
% make fetch-list FETCH_CMD=wget DISTDIR=/tmp/distfiles >/tmp/fetch.sh
% scp /tmp/fetch.sh work:/tmp

At work:

% sh /tmp/fetch.sh

then tar up /tmp/distfiles and take it home.

If you have a machine running NetBSD, and you want to get all distfiles (even
ones that aren't for your machine architecture), you can do so by using the
above-mentioned make fetch-list approach, or fetch the distfiles directly by
running:

% make mirror-distfiles

If you even decide to ignore NO_{SRC,BIN}_ON_{FTP,CDROM}, then you can get
everything by running:

% make fetch NO_SKIP=yes

6.11. What does "Don't know how to make /usr/share/tmac/tmac.andoc" mean?

When compiling the pkgtools/pkg_install package, you get the error from make
that it doesn't know how to make /usr/share/tmac/tmac.andoc? This indicates
that you don't have installed the "text" set (nroff, ...) from the NetBSD base
distribution on your machine. It is recommended to do that to format manpages.

In the case of the pkgtools/pkg_install package, you can get away with setting
NOMAN=YES either in the environment or in /etc/mk.conf.

6.12. What does "Could not find bsd.own.mk" mean?

You didn't install the compiler set, comp.tgz, when you installed your NetBSD
machine. Please get it and install it, by extracting it in /:

# cd /
# tar --unlink -zxvpf .../comp.tgz

comp.tgz is part of every NetBSD release. Get the one that corresponds to your
release (determine via uname -r).

6.13. Using 'sudo' with pkgsrc

When installing packages as non-root user and using the just-in-time su(1)
feature of pkgsrc, it can become annoying to type in the root password for each
required package installed. To avoid this, the sudo package can be used, which
does password caching over a limited time. To use it, install sudo (either as
binary package or from security/sudo) and then put the following into your /etc
/mk.conf:

.if exists(${LOCALBASE}/bin/sudo)
SU_CMD=${LOCALBASE}/bin/sudo /bin/sh -c
.endif

6.14. How do I change the location of configuration files?

As the system administrator, you can choose where configuration files are
installed. The default settings make all these files go into ${PREFIX}/etc or
some of its subdirectories; this may be suboptimal depending on your
expectations (e.g., a read-only, NFS-exported PREFIX with a need of per-machine
configuration of the provided packages).

In order to change the defaults, you can modify the PKG_SYSCONFBASE variable
(in /etc/mk.conf) to point to your preferred configuration directory; some
common examples include /etc or /etc/pkg.

Furthermore, you can change this value on a per-package basis by setting the
PKG_SYSCONFDIR.${PKG_SYSCONFVAR} variable. PKG_SYSCONFVAR's value usually
matches the name of the package you would like to modify, that is, the contents
of PKGBASE.

Note that, after changing these settings, you must rebuild and reinstall any
affected packages.

6.15. Automated security checks

Please be aware that there can often be bugs in third-party software, and some
of these bugs can leave a machine vulnerable to exploitation by attackers. In
an effort to lessen the exposure, the NetBSD packages team maintains a database
of known-exploits to packages which have at one time been included in pkgsrc.
The database can be downloaded automatically, and a security audit of all
packages installed on a system can take place. To do this, install the security
/audit-packages package. It has two components:

 1. download-vulnerability-list, an easy way to download a list of the security
    vulnerabilities information. This list is kept up to date by the NetBSD
    security officer and the NetBSD packages team, and is distributed from the
    NetBSD ftp server:

    ftp://ftp.NetBSD.org/pub/NetBSD/packages/distfiles/pkg-vulnerabilities

 2. audit-packages, an easy way to audit the current machine, checking each
    vulnerability which is known. If a vulnerable package is installed, it will
    be shown by output to stdout, including a description of the type of
    vulnerability, and a URL containing more information.

Use of the security/audit-packages package is strongly recommended! After
"audit-packages" is installed, please read the package's message, which you can
get by running pkg_info -D audit-package.

Whenever you're preparing a package, there are a number of files involved which
are described in the following sections.

7.1. Makefile

Building, installation and creation of a binary package are all controlled by
the package's Makefile. The Makefile describes various things about a package,
for example from where to get it, how to configure, build, and install it.

A package Makefile contains several sections that describe the package.

In the first section there are the following variables, which should appear
exactly in the order given here.

  * DISTNAME is the basename of the distribution file to be downloaded from the
    package's website.

  * PKGNAME is the name of the package, as used by pkgsrc. You only need to
    provide it if it differs from DISTNAME. Usually it is the directory name
    together with the version number. It must match the regular expression ^
    [A-Za-z0-9][A-Za-z0-9-_.+]*$, that is, it starts with a letter or digit,
    and contains only letters, digits, dashes, underscores, dots and plus
    signs.

  * CATEGORIES is a list of categories which the package fits in. You can
    choose any of the top-level directories of pkgsrc for it.

  * MASTER_SITES is a list of URLs where the distribution files can be
    downloaded. Each URL must end with a slash.

The second section contains the following variables.

  * MAINTAINER is the mail address of the package's maintainer, which is the
    person you can contact when the package does not work.

  * HOMEPAGE is a URL where users can find more information about the package.

  * COMMENT is a one-line comment about the purpose of the package.

The MASTER_SITES may be set to one of the predefined sites:

        ${MASTER_SITE_APACHE}
        ${MASTER_SITE_BACKUP}
        ${MASTER_SITE_CYGWIN}
        ${MASTER_SITE_DEBIAN}
        ${MASTER_SITE_FREEBSD}
        ${MASTER_SITE_FREEBSD_LOCAL}
        ${MASTER_SITE_GNOME}
        ${MASTER_SITE_GNU}
        ${MASTER_SITE_GNUSTEP}
        ${MASTER_SITE_IFARCHIVE}
        ${MASTER_SITE_MOZILLA}
        ${MASTER_SITE_OPENOFFICE}
        ${MASTER_SITE_PERL_CPAN}
        ${MASTER_SITE_R_CRAN}
        ${MASTER_SITE_SOURCEFORGE}
        ${MASTER_SITE_SUNSITE}
        ${MASTER_SITE_SUSE}
        ${MASTER_SITE_TEX_CTAN}
        ${MASTER_SITE_XCONTRIB}
        ${MASTER_SITE_XEMACS}


If one of these predefined sites is chosen, you may require the ability to
specify a subdirectory of that site. Since these macros may expand to more than
one actual site, you must use the following construct to specify a
subdirectory:

        ${MASTER_SITE_GNU:=subdirectory/name/}
        ${MASTER_SITE_SOURCEFORGE:=project_name/}

Note the trailing slash after the subdirectory name.

Note

MASTER_SITE_SUBDIR has been deprecated and should no longer be used.

If the package has multiple DISTFILES or multiple PATCHFILES from different
sites, set SITES_foo to a list of URI's where file "foo" may be found. "foo"
includes the suffix, e.g.

DISTFILES=      ${DISTNAME}${EXTRACT_SUFX}
DISTFILES+=     foo-file.tar.gz
SITES_foo-file.tar.gz=http://www.somewhere.com/somehow/ \
        http://www.somewhereelse.com/mirror/somehow/

Note that the normal default setting of DISTFILES must be made explicit if you
want to add to it (rather than replace it), as you usually would.

Currently the following values are available for CATEGORIES. If more than one
is used, they need to be separated by spaces:

archivers     cross         geography     meta-pkgs     security
audio         databases     graphics      misc          shells

biology       editors       inputmethod   net           textproc

chat          finance       mail          parallel      wm
comms         fonts         math          pkgtools      www
converters    games         mbone         print         x11

Please pay attention to the following gotchas:

  * Add MANCOMPRESSED if manpages are installed in compressed form by the
    package; see comment in bsd.pkg.mk.

  * Replace /usr/local with "${PREFIX}" in all files (see patches, below).

  * If the package installs any info files, see Section 14.5.7, "Packages
    installing info files".

  * Set MAINTAINER to be yourself. If you really can't maintain the package for
    future updates, set it to <tech-pkg@NetBSD.org>.

  * If a home page for the software in question exists, add the variable
    HOMEPAGE right after MAINTAINER. The value of this variable should be the
    URL for the home page.

  * Be sure to set the COMMENT variable to a short description of the package,
    not containing the pkg's name.

7.2. distinfo

Most important, the mandatory message digest, or checksum, of all the distfiles
needed for the package to compile, confirming they match the original file
distributed by the author. This ensures that the distfile retrieved from the
Internet has not been corrupted during transfer or altered by a malign force to
introduce a security hole. It is generated using the make makesum command. The
digest algorithm used was, at one stage, md5, but that was felt lacking
compared to sha1, and so sha1 is now the default algorithm. The distfile size
is also generated and stored in new distinfo files. The pkgtools/digest utility
calculates all of the digests in the distinfo file, and it provides various
different algorithms. At the current time, the algorithms provided are: md5,
rmd160, sha1, sha256, sha384 and sha512.

Some packages have different sets of distfiles on a per architecture basis, for
example www/navigator). These are kept in the same distinfo file and care
should be taken when upgrading such a package to ensure distfile information is
not lost.

The message digest/checksum for all the official patches found in the patches/
directory (see Section 7.3, "patches/*") for the package is also stored in the
distinfo file. This is a message digest/checksum of all lines in the patch file
except the NetBSD RCS Id. This file is generated by invoking make makepatchsum
(or make mps if you're in a hurry).

7.3. patches/*

This directory contains files that are used by the patch(1) command to modify
the sources as distributed in the distribution file into a form that will
compile and run perfectly on NetBSD. The files are applied successively in
alphabetic order (as returned by a shell "patches/patch-*" glob expansion), so
patch-aa is applied before patch-ab, etc.

The patch-* files should be in diff -bu format, and apply without a fuzz to
avoid problems. (To force patches to apply with fuzz you can set
PATCH_FUZZ_FACTOR=-F2). Furthermore, do not put changes for more than one file
into a single patch-file, as this will make future modifications more
difficult.

Similar, a file should be patched at most once, not several times by several
different patches. If a file needs several patches, they should be combined
into one file.

One important thing to mention is to pay attention that no RCS IDs get stored
in the patch files, as these will cause problems when later checked into the
NetBSD CVS tree. Use the pkgdiff from the pkgtools/pkgdiff package to avoid
these problems.

For even more automation, we recommend using mkpatches from the same package to
make a whole set of patches. You just have to backup files before you edit them
to filename.orig, e.g. with cp -p filename filename.orig or, easier, by using
pkgvi again from the same package. If you upgrade a package this way, you can
easily compare the new set of patches with the previously existing one with
patchdiff.

When you have finished a package, remember to generate the checksums for the
patch files by using the make makepatchsum command, see Section 7.2, "distinfo"
.

Patch files that are distributed by the author or other maintainers can be
listed in $PATCHFILES.

If it is desired to store any patches that should not be committed into pkgsrc,
they can be kept outside the pkgsrc tree in the $LOCALPATCHES directory. The
directory tree there is expected to have the same "category/package" structure
as pkgsrc, and patches are expected to be stored inside these dirs (also known
as $LOCALPATCHES/$PKGPATH). For example if you want to keep a private patch for
pkgsrc/graphics/png, keep it in $LOCALPATCHES/graphics/png/mypatch. All files
in the named directory are expected to be patch files, and they are applied
after pkgsrc patches are applied.

7.4. Other mandatory files

DESCR

    A multi-line description of the piece of software. This should include any
    credits where they are due. Please bear in mind that others do not share
    your sense of humour (or spelling idiosyncrasies), and that others will
    read everything that you write here.

PLIST

    This file governs the files that are installed on your system: all the
    binaries, manual pages, etc. There are other directives which may be
    entered in this file, to control the creation and deletion of directories,
    and the location of inserted files. See Chapter 9, PLIST issues for more
    information.

7.5. Optional files

INSTALL

    This shell script is invoked twice by pkg_add(1). First time after package
    extraction and before files are moved in place, the second time after the
    files to install are moved in place. This can be used to do any custom
    procedures not possible with @exec commands in PLIST. See pkg_add(1) and
    pkg_create(1) for more information.

DEINSTALL

    This script is executed before and after any files are removed. It is this
    script's responsibility to clean up any additional messy details around the
    package's installation, since all pkg_delete knows is how to delete the
    files created in the original distribution. See pkg_delete(1) and
    pkg_create(1) for more information.

MESSAGE

    Display this file after installation of the package. Useful for things like
    legal notices on almost-free software and hints for updating config files
    after installing modules for apache, PHP etc. Please note that you can
    modify variables in it easily by using MESSAGE_SUBST in the package's
    Makefile:

    MESSAGE_SUBST+=  SOMEVAR="somevalue"

    replaces "${SOMEVAR}" with "somevalue" in MESSAGE.

7.6. work*

When you type make the distribution files are unpacked into this directory. It
can be removed by running make clean. Besides the sources, this directory is
also used to keep various timestamp files.

If a package doesn't create a subdirectory for itself (like GNU software does,
for instance), but extracts itself in the current directory, you should set
WRKSRC accordingly, e.g. editors/sam again, but the quick answer is:

WRKSRC=             ${WRKDIR}

Please note that the old NO_WRKSUBDIR has been deprecated and should not be
used. Also, if your package doesn't create a subdir with the name of DISTNAME
but some different name, set WRKSRC to point to the proper name in ${WRKDIR}.
See lang/tcl and x11/tk for examples, and here is another one:

WRKSRC=         ${WRKDIR}/${DISTNAME}/unix

The name of the working directory created by pkgsrc is work by default. If the
same pkgsrc tree should be used on several different platforms, the variable
OBJMACHINE can be set in /etc/mk.conf to attach the platform to the directory
name, e.g. work.i386 or work.sparc.

7.7. files/*

If you have any files that you wish to be placed in the package prior to
configuration or building, you could place these files here and use a "${CP}"
command in the "pre-configure" target to achieve this. Alternatively, you could
simply diff the file against /dev/null and use the patch mechanism to manage
the creation of this file.

    8.2.5. Workaround for a bug in BSD Make

Pkgsrc consists of many Makefile fragments, each of which forms a well-defined
part of the pkgsrc system. Using the make(1) system as a programming language
for a big system like pkgsrc requires some discipline to keep the code correct
and understandable.

The basic ingredients for Makefile programming are variables (which are
actually macros) and shell commands. Among these shell commands may even be
more complex ones like awk(1) programs. To make sure that every shell command
runs as intended it is necessary to quote all variables correctly when they are
used.

This chapter describes some patterns, that appear quite often in Makefiles,
including the pitfalls that come along with them.

8.1. Makefile variables

Makefile variables contain strings that can be processed using the five
operators ``='', ``+='', ``?='', ``:='', and ``!='', which are described in the
make(1) man page.

When a variable's value is parsed from a Makefile, the hash character ``#'' and
the backslash character ``\'' are handled specially. If a backslash is followed
by a newline, any whitespace immediately in front of the backslash, the
backslash, the newline, and any whitespace immediately behind the newline are
replaced with a single space. A backspace character and an immediately
following hash character are replaced with a single hash character. Otherwise
the backslash is passed as is. In a variable assignment, any hash character
that is not preceded by a backslash starts a comment that continues upto the
end of the logical line.

Note: Because of this parsing algorithm the only way to create a variable
consisting of a single backslash is using the ``!='' operator, for example:
BACKSLASH!=echo "\\".

So far for defining variables. The other thing you can do with variables is
evaluating them. A variable is evaluated when it is part of the right side of
the ``:='' or the ``!='' operator, or directly before executing a shell command
which the variable is part of. In all other cases make(1) performs lazy
evaluation, that is, variables are not evaluated until there's no other way.
The ``modifiers'' mentioned in the man page also evaluate the variable.

Some of the modifiers split the string into words and then operate on the
words, others operate on the string as a whole. When a string is splitted into
words, it is splitted as you would expect it from sh(1).

No rule without exception?the .for loop does not follow the shell quoting rules
but splits at sequences of whitespace.

There are several types of variables that should be handled differently.
Strings and two types of lists.

  * Strings can contain arbitrary characters. Nevertheless you should restrict
    yourself to only using printable characters. Examples are PREFIX and
    COMMENT.

  * Internal lists are lists that are never exported to any shell command.
    Their elements are separated by whitespace. Therefore the elements
    themselves cannot have embedded whitespace. Any other characters are
    allowed. Internal lists can be used in .for loops. Examples are DEPENDS and
    BUILD_DEPENDS.

  * External lists are lists that may be exported to a shell command. Their
    elements can contain any characters, including whitespace. That's why they
    cannot be used in .for loops. Examples are DISTFILES and MASTER_SITES.

8.1.1. Naming conventions

  * All variable names starting with an underscore are reserved for use by the
    pkgsrc infrastructure. They shall not be used by package Makefiles.

  * In .for loops you should use lowercase variable names for the iteration
    variables.

  * All list variables should have a ``plural'' name, e.g. PKG_OPTIONS or
    DISTFILES.

8.2. Code snippets

This section presents you with some code snippets you should use in your own
code. If you don't find anything appropriate here, you should test your code
and add it here.

8.2.1. Adding things to a list

STRING=                 foo * bar `date`
INT_LIST=               # empty
ANOTHER_INT_LIST=       apache-[0-9]*:../../www/apache
EXT_LIST=               # empty
ANOTHER_EXT_LIST=       a=b c=d

INT_LIST+=              ${STRING}               # 1
INT_LIST+=              ${ANOTHER_INT_LIST}     # 2
EXT_LIST+=              ${STRING:Q}             # 3
EXT_LIST+=              ${ANOTHER_EXT_LIST}     # 4


When you add a string to an external list (example 3), it must be quoted. In
all other cases, you must not add a quoting level. You must not merge internal
and external lists, unless you are sure that all entries are correctly
interpreted in both lists.

8.2.2. Converting an internal list into an external list

EXT_LIST=       # empty
.for i in ${INT_LIST}
EXT_LIST+=      ${i:Q}""
.endfor


This code converts the internal list INT_LIST into the external list EXT_LIST.
As the elements of an internal list are unquoted they must be quoted here. The
reason for appending "" is explained below.

8.2.3. Passing variables to a shell command

STRING=         foo bar <    > * `date` $$HOME ' "
EXT_LIST=       string=${STRING:Q} x=second\ item

all:
        echo ${STRING}                  # 1
        echo "${STRING}"                # 2
        echo "${STRING:Q}"              # 3
        echo ${STRING:Q}                # 4
        echo x${STRING:Q} | sed 1s,.,,  # 5
        env ${EXT_LIST} /bin/sh -c 'echo "$$string"; echo "$$x"'


Example 1 leads to a syntax error in the shell, as the characters are just
copied.

Example 2 leads to a syntax error too, and if you leave out the last "
character from ${STRING}, date(1) will be executed. The $HOME shell variable
would be evaluated, too.

Example 3 outputs each space character preceded by a backslash (or not),
depending on the implementation of the echo(1) command.

Example 4 handles correctly every string that does not start with a dash. In
that case, the result depends on the implementation of the echo(1) command. As
long as you can guarantee that your input does not start with a dash this form
is appropriate.

Example 5 handles even the case of a leading dash correctly.

The EXT_LIST does not need to be quoted because the quoting has already be done
when adding elements to the list.

As internal lists shall not be passed to the shell, there is no example for it.

8.2.4. Quoting guideline

There are many possible sources of wrongly quoted variables. This section lists
some of the commonly known ones.

  * Whenever you use the value of a list, think about what happens to leading
    or trailing whitespace. If the list is a well-formed shell expression you
    can apply the :M* modifier to strip leading and trailing whitespace from
    each word. The :M operator first splits its argument according to the rules
    of the shell, and then creates a new list consisting of all words that
    match the shell glob expression *, that is: all. One class of situations
    where this is needed is when adding a variable like CPPFLAGS to
    CONFIGURE_ARGS. If the configure script invokes other configure scripts it
    strips the leading and trailing whitespace from the variable and then
    passes it to the other configure scripts. But these configure scripts
    expect the (child) CPPFLAGS variable to be the same as the parent CPPFLAGS.
    That's why we better pass the CPPFLAGS value properly trimmed. And here is
    how we do it:

    CPPFLAGS=               # empty
    CPPFLAGS+=              -Wundef -DPREFIX=\"${PREFIX:Q}\"
    CPPFLAGS+=              ${MY_CPPFLAGS}

    CONFIGURE_ARGS+=        CPPFLAGS=${CPPFLAGS:M*:Q}

    all:
            echo x${CPPFLAGS:Q}x            # leading and trailing whitespace
            echo x${CONFIGURE_ARGS}x        # properly trimmed


  * The example above contains one bug: The ${PREFIX} is a properly quoted
    shell expression, but there is the C compiler after it, which also expects
    a properly quoted string (this time in C syntax). The version above is
    therefore only correct if ${PREFIX} does not have embedded backslashes or
    double quotes. If you want to allow these, you have to add another layer of
    quoting to each variable that is used as a C string literal. You cannot use
    the :Q operator for it, as this operator only works for the shell.

  * Whenever a variable can be empty the :Q operator can have surprising
    results. Here are two completely different cases which can be solved with
    the same trick.

    EMPTY=                  # empty
    empty_test:
            for i in a ${EMPTY:Q} c; do \
                    echo "$$i"; \
            done

    for_test:
    .for i in a:\ a:\test.txt
            echo ${i:Q}
            echo "foo"
    .endfor


    The first example will only print two of the three lines we might have
    expected. This is because ${EMPTY:Q} expands to the empty string, which the
    shell cannot see. The workaround is to write ${EMPTY:Q}"". This pattern can
    be often found as ${TEST} -z ${VAR:Q} or as ${TEST} -f ${FNAME:Q} (both of
    these are wrong).

    The second example will only print three lines instead of four. The first
    line looks like a:\ echo foo. This is because the backslash of the value a:
    \ is interpreted as a line-continuation by make(1), which makes the second
    line the arguments of the echo(1) command from the first line. To avoid
    this, write ${i:Q}"".

8.2.5. Workaround for a bug in BSD Make

The pkgsrc bmake program does not handle the following assignment correctly. In
case _othervar_ contains a ``-'' character, one of the closing braces is
included in ${VAR} after this code executes.

        VAR:= ${VAR:N${_othervar_:C/-//}}


For a more complex code snippet and a workaround, see the package regress/
make-quoting, testcase bug1.

9.6. Changing PLIST source with PLIST_SRC
9.7. Platform specific and differing PLISTs
9.8. Sharing directories between packages

The PLIST file contains a package's "packing list", i.e. a list of files that
belong to the package (relative to the ${PREFIX} directory it's been installed
in) plus some additional statements - see the pkg_create(1) manpage for a full
list. This chapter addresses some issues that need attention when dealing with
the PLIST file (or files, see below!).

9.1. RCS ID

Be sure to add a RCS ID line as the first thing in any PLIST file you write:

@comment $NetBSD$

9.2. Semi-automatic PLIST generation

You can use the make print-PLIST command to output a PLIST that matches any new
files since the package was extracted. See Section 13.3, "Other helpful
targets" for more information on this target.

9.3. Tweaking output of make print-PLIST

If you have used any of the *-dirs packages, as explained in Section 9.8,
"Sharing directories between packages", you may have noticed that make
print-PLIST outputs a set of @comments instead of real @dirrm lines. You can
also do this for specific directories and files, so that the results of that
command are very close to reality. This helps a lot during the update of
packages.

The PRINT_PLIST_AWK variable takes a set of AWK patterns and actions that are
used to filter the output of print-PLIST. You can append any chunk of AWK
scripting you like to it, but be careful with quoting.

For example, to get all files inside the libdata/foo directory removed from the
resulting PLIST:

      PRINT_PLIST_AWK+= /^libdata\/foo/ { next; }


And to get all the @dirrm lines referring to a specific (shared) directory
converted to @comments:

      PRINT_PLIST_AWK+= /^@dirrm share\/specific/ { print "@comment " $$0; next; }


9.4. Variable substitution in PLIST

A number of variables are substituted automatically in PLISTs when a package is
installed on a system. This includes the following variables:

${MACHINE_ARCH}, ${MACHINE_GNU_ARCH}

    Some packages like emacs and perl embed information about which
    architecture they were built on into the pathnames where they install their
    file. To handle this case, PLIST will be preprocessed before actually used,
    and the symbol "${MACHINE_ARCH}" will be replaced by what uname -p gives.
    The same is done if the string ${MACHINE_GNU_ARCH} is embedded in PLIST
    somewhere - use this on packages that have GNU autoconf created configure
    scripts.

    Legacy note

    There used to be a symbol "$ARCH" that was replaced by the output of uname
    -m, but that's no longer supported and has been removed.

${OPSYS}, ${LOWER_OPSYS}, ${OS_VERSION}

    Some packages want to embed the OS name and version into some paths. To do
    this, use these variables in the PLIST:

      * ${OPSYS} - output of "uname -s"

      * ${LOWER_OPSYS} - lowercase common name (eg. "solaris")

      * ${OS_VERSION} - "uname -r"

${PKGLOCALEDIR}

    Packages that install locale files should list them in the PLIST as "$
    {PKGLOCALEDIR}/locale/de/LC_MESSAGES/..." instead of "share/locale/de/
    LC_MESSAGES/...". This properly handles the fact that different operating
    systems expect locale files to be either in share or lib by default.

For a complete list of values which are replaced by default, please look in
bsd.pkg.mk (and search for PLIST_SUBST).

If you want to change other variables not listed above, you can add variables
and their expansions to this variable in the following way, similar to
MESSAGE_SUBST (see Section 7.5, "Optional files"):

PLIST_SUBST+=    SOMEVAR="somevalue"

This replaces all occurrences of "${SOMEVAR}" in the PLIST with "somevalue".

9.5. Manpage-compression

Manpages should be installed in compressed form if MANZ is set (in bsd.own.mk),
and uncompressed otherwise. To handle this in the PLIST file, the suffix ".gz"
is appended/removed automatically for manpages according to MANZ and
MANCOMPRESSED being set or not, see above for details. This modification of the
PLIST file is done on a copy of it, not PLIST itself.

9.6. Changing PLIST source with PLIST_SRC

To use one or more files as source for the PLIST used in generating the binary
package, set the variable PLIST_SRC to the names of that file(s). The files are
later concatenated using cat(1), and order of things is important.

9.7. Platform specific and differing PLISTs

Some packages decide to install a different set of files based on the operating
system being used. These differences can be automatically handled by using the
following files:

  * PLIST.common

  * PLIST.${OPSYS}

  * PLIST.${MACHINE_ARCH}

  * PLIST.${OPSYS}-${MACHINE_ARCH}

  * PLIST.common_end

9.8. Sharing directories between packages

A "shared directory" is a directory where multiple (and unrelated) packages
install files. These directories are problematic because you have to add
special tricks in the PLIST to conditionally remove them, or have some
centralized package handle them.

Within pkgsrc, you'll find both approaches. If a directory is shared by a few
unrelated packages, it's often not worth to add an extra package to remove it.
Therefore, one simply does:

      @unexec ${RMDIR} %D/path/to/shared/directory 2>/dev/null || ${TRUE}


in the PLISTs of all affected packages, instead of the regular "@dirrm" line.

However, if the directory is shared across many packages, two different
solutions are available:

 1. If the packages have a common dependency, the directory can be removed in
    that. For example, see textproc/scrollkeeper, which removes the shared
    directory share/omf.

 2. If the packages using the directory are not related at all (they have no
    common dependencies), a *-dirs package is used.

From now on, we'll discuss the second solution. To get an idea of the *-dirs
packages available, issue:

      % cd .../pkgsrc
      % ls -d */*-dirs


Their use from other packages is very simple. The USE_DIRS variable takes a
list of package names (without the "-dirs" part) together with the required
version number (always pick the latest one when writing new packages).

For example, if a package installs files under share/applications, it should
have the following line in it:

      USE_DIRS+= xdg-1.1


After regenerating the PLIST using make print-PLIST, you should get the right
(commented out) lines.

Note that, even if your package is using $X11BASE, it must not depend on the
*-x11-dirs packages. Just specify the name without that part and pkgsrc (in
particular, mk/dirs.mk) will take care of it.

Buildlink is a framework in pkgsrc that controls what headers and libraries are
seen by a package's configure and build processes. This is implemented in a two
step process:

 1. Symlink headers and libraries for dependencies into BUILDLINK_DIR, which by
    default is a subdirectory of WRKDIR.

 2. Create wrapper scripts that are used in place of the normal compiler tools
    that translate -I${LOCALBASE}/include and -L${LOCALBASE}/lib into
    references to BUILDLINK_DIR. The wrapper scripts also make native compiler
    on some operating systems look like GCC, so that packages that expect GCC
    won't require modifications to build with those native compilers.

This normalizes the environment in which a package is built so that the package
may be built consistently despite what other software may be installed. Please
note that the normal system header and library paths, e.g. /usr/include, /usr/
lib, etc., are always searched -- buildlink3 is designed to insulate the
package build from non-system-supplied software.

10.1. Converting packages to use buildlink3

The process of converting packages to use the buildlink3 framework
("bl3ifying") is fairly straightforward. The things to keep in mind are:

 1. Ensure that the build always calls the wrapper scripts instead of the
    actual toolchain. Some packages are tricky, and the only way to know for
    sure is the check ${WRKDIR}/.work.log to see if the wrappers are being
    invoked.

 2. Don't override PREFIX from within the package Makefile, e.g. Java VMs,
    standalone shells, etc., because the code to symlink files into $
    {BUILDLINK_DIR} looks for files relative to "pkg_info -qp pkgname".

 3. Remember that only the buildlink3.mk files that you list in a package's
    Makefile are added as dependencies for that package.

If a dependency on a particular package is required for its libraries and
headers, then we replace:

DEPENDS+=   foo>=1.1.0:../../category/foo

with

.include "../../category/foo/buildlink3.mk"

There are several buildlink3.mk files in pkgsrc/mk that handle special package
issues:

  * bdb.buildlink3.mk chooses either the native or a pkgsrc Berkeley DB
    implementation based on the values of BDB_ACCEPTED and BDB_DEFAULT.

  * curses.buildlink3.mk If the system comes with neither Curses nor NCurses,
    this will take care to install the devel/ncurses package.

  * krb5.buildlink3.mk uses the value of KRB5_ACCEPTED to choose between adding
    a dependency on Heimdal or MIT-krb5 for packages that require a Kerberos 5
    implementation.

  * motif.buildlink3.mk checks for a system-provided Motif installation or adds
    a dependency on x11/lesstif or x11/openmotif;

  * ossaudio.buildlink3.mk defines several variables that may be used by
    packages that use the Open Sound System (OSS) API;

  * pgsql.buildlink3.mk will accept either Postgres 7.3 or 7.4, whichever is
    found installed. See the file for more information.

  * pthread.buildlink3.mk uses the value of PTHREAD_OPTS and checks for native
    pthreads or adds a dependency on devel/pth as needed;

  * xaw.buildlink3.mk uses the value of XAW_TYPE to choose a particular Athena
    widgets library.

The comments in those buildlink3.mk files provide a more complete description
of how to use them properly.

10.2. Writing buildlink3.mk files

A package's buildlink3.mk file is included by Makefiles to indicate the need to
compile and link against header files and libraries provided by the package. A
buildlink3.mk file should always provide enough information to add the correct
type of dependency relationship and include any other buildlink3.mk files that
it needs to find headers and libraries that it needs in turn.

To generate an initial buildlink3.mk file for further editing, Rene Hexel's
pkgtools/createbuildlink package is highly recommended. For most packages, the
following command will generate a good starting point for buildlink3.mk files:

% cd pkgsrc/category/pkgdir
% createbuildlink -3 >buildlink3.mk

10.2.1. Anatomy of a buildlink3.mk file

The following real-life example buildlink3.mk is taken from pkgsrc/graphics/
tiff:

# $NetBSD: buildlink3.mk,v 1.7 2004/03/18 09:12:12 jlam Exp $

BUILDLINK_DEPTH:=       ${BUILDLINK_DEPTH}+
TIFF_BUILDLINK3_MK:=    ${TIFF_BUILDLINK3_MK}+

.if !empty(BUILDLINK_DEPTH:M+)
BUILDLINK_DEPENDS+=     tiff
.endif

BUILDLINK_PACKAGES:=    ${BUILDLINK_PACKAGES:Ntiff}
BUILDLINK_PACKAGES+=    tiff

.if !empty(TIFF_BUILDLINK3_MK:M+)
BUILDLINK_DEPENDS.tiff+=        tiff>=3.6.1
BUILDLINK_PKGSRCDIR.tiff?=      ../../graphics/tiff
.endif  # TIFF_BUILDLINK3_MK

.include "../../devel/zlib/buildlink3.mk"
.include "../../graphics/jpeg/buildlink3.mk"

BUILDLINK_DEPTH:=       ${BUILDLINK_DEPTH:S/+$//}

The header and footer manipulate BUILDLINK_DEPTH, which is common across all
buildlink3.mk files and is used to track at what depth we are including
buildlink3.mk files.

The first section controls if the dependency on pkg is added. BUILDLINK_DEPENDS
is the global list of packages for which dependencies are added by buildlink3.

The second section advises pkgsrc that the buildlink3.mk file for pkg has been
included at some point. BUILDLINK_PACKAGES is the global list of packages for
which buildlink3.mk files have been included. It must always be appended to
within a buildlink3.mk file.

The third section is protected from multiple inclusion and controls how the
dependency on pkg is added. Several important variables are set in the section:

  * BUILDLINK_DEPENDS.pkg is the actual dependency recorded in the installed
    package; this should always be set using += to ensure that we're appending
    to any pre-existing list of values. This variable should be set to the
    first version of the package that had the last change in the major number
    of a shared library or that had a major API change.

  * BUILDLINK_PKGSRCDIR.pkg is the location of the pkg pkgsrc directory;

  * BUILDLINK_DEPMETHOD.pkg (not shown above) controls whether we use
    BUILD_DEPENDS or DEPENDS to add the dependency on pkg. The build dependency
    is selected by setting BUILDLINK_DEPMETHOD.pkg to "build". By default, the
    full dependency is used.

  * BUILDLINK_INCDIRS.pkg and BUILDLINK_LIBDIRS. pkg (not shown above) are
    lists of subdirectories of ${BUILDLINK_PREFIX.pkg} to add to the header and
    library search paths. These default to "include" and "lib" respectively.

  * BUILDLINK_CPPFLAGS.pkg (not shown above) is the list of preprocessor flags
    to add to CPPFLAGS, which are passed on to the configure and build phases.
    The "-I" option should be avoided and instead be handled using
    BUILDLINK_INCDIRS.pkg as above.

The following variables are all optionally defined within this second section
(protected against multiple inclusion) and control which package files are
symlinked into ${BUILDLINK_DIR} and how their names are transformed during the
symlinking:

  * BUILDLINK_FILES.pkg (not shown above) is a shell glob pattern relative to $
    {BUILDLINK_PREFIX.pkg} to be symlinked into ${BUILDLINK_DIR}, e.g. include/
    *.h.

  * BUILDLINK_FILES_CMD.pkg (not shown above) is a shell pipeline that outputs
    to stdout a list of files relative to ${BUILDLINK_PREFIX.pkg}. The
    resulting files are to be symlinked into ${BUILDLINK_DIR}. By default, this
    takes the +CONTENTS of a pkg and filters it through $
    {BUILDLINK_CONTENTS_FILTER.pkg}.

  * BUILDLINK_CONTENTS_FILTER.pkg (not shown above) is a filter command that
    filters +CONTENTS input into a list of files relative to $
    {BUILDLINK_PREFIX.pkg} on stdout. By default for overwrite packages,
    BUILDLINK_CONTENTS_FILTER.pkg outputs the contents of the include and lib
    directories in the package +CONTENTS, and for pkgviews packages, it outputs
    any libtool archives in lib directories.

  * BUILDLINK_TRANSFORM.pkg (not shown above) is a list of sed arguments used
    to transform the name of the source filename into a destination filename,
    e.g. -e "s|/curses.h|/ncurses.h|g".

The last section includes any buildlink3.mk needed for pkg's library
dependencies. Including these buildlink3.mk files means that the headers and
libraries for these dependencies are also symlinked into ${BUILDLINK_DIR}
whenever the pkg buildlink3.mk file is included.

10.2.2. Updating BUILDLINK_DEPENDS. pkg in buildlink3.mk files

There are two situations that require increasing the dependency listed in
BUILDLINK_DEPENDS.pkg after a package update:

 1. if the sonames (major number of the library version) of any installed
    shared libraries change;

 2. if the API or interface to the header files change.

In these cases, BUILDLINK_DEPENDS.pkg should be adjusted to require at least
the new package version. In some cases, the packages that depend on this new
version may need their PKGREVISIONs increased and, if they have buildlink3.mk
files, their BUILDLINK_DEPENDS. pkg adjusted, too. This is needed so that
binary packages made using it will require the correct package dependency and
not settle for an older one which will not contain the necessary shared
libraries.

Please take careful consideration before adjusting BUILDLINK_DEPENDS.pkg as we
don't want to cause unneeded package deletions and rebuilds. In many cases, new
versions of packages work just fine with older dependencies. See Section
14.1.4, "Handling dependencies" and Chapter 10, Buildlink methodology for more
information about dependencies on other packages, including the
BUILDLINK_RECOMMENDED and RECOMMENDED definitions.

10.3. Writing builtin.mk files

Some packages in pkgsrc install headers and libraries that coincide with
headers and libraries present in the base system. Aside from a buildlink3.mk
file, these packages should also include a builtin.mk file that includes the
necessary checks to decide whether using the built-in software or the pkgsrc
software is appropriate.

The only requirements of a builtin.mk file for pkg are:

 1. It should set USE_BUILTIN.pkg to either "yes" or "no" after it is included.

 2. It should not override any USE_BUILTIN.pkg which is already set before the
    builtin.mk file is included.

 3. It should be written to allow multiple inclusion. This is very important
    and takes careful attention to Makefile coding.

10.3.1. Anatomy of a builtin.mk file

The following is the recommended template for builtin.mk files:

.if !defined(IS_BUILTIN.foo)
#
# IS_BUILTIN.foo is set to "yes" or "no" depending on whether "foo"
# genuinely exists in the system or not.
#
IS_BUILTIN.foo?=        no

# BUILTIN_PKG.foo should be set here if "foo" is built-in and its package
# version can be determined.
#
.  if !empty(IS_BUILTIN.foo:M[yY][eE][sS])
BUILTIN_PKG.foo?=       foo-1.0
.  endif
.endif  # IS_BUILTIN.foo

.if !defined(USE_BUILTIN.foo)
USE_BUILTIN.foo?=       ${IS_BUILTIN.foo}
.  if defined(BUILTIN_PKG.foo)
.    for _depend_ in ${BUILDLINK_DEPENDS.foo}
.      if !empty(USE_BUILTIN.foo:M[yY][eE][sS])
USE_BUILTIN.foo!=                                                       \
      if ${PKG_ADMIN} pmatch '${_depend_}' ${BUILTIN_PKG.foo}; then     \
              ${ECHO} "yes";                                            \
      else                                                              \
              ${ECHO} "no";                                             \
      fi
.      endif
.    endfor
.  endif
.endif  # USE_BUILTIN.foo

CHECK_BUILTIN.foo?=     no
.if !empty(CHECK_BUILTIN.foo:M[nN][oO])
#
# Here we place code that depends on whether USE_BUILTIN.foo is set to
# "yes" or "no".
#
.endif  # CHECK_BUILTIN.foo


The first section sets IS_BUILTIN.pkg depending on if pkg really exists in the
base system. This should not be a base system software with similar
functionality to pkg; it should only be "yes" if the actual package is included
as part of the base system. This variable is only used internally within the
builtin.mk file.

The second section sets BUILTIN_PKG.pkg to the version of pkg in the base
system if it exists (if IS_BUILTIN.pkg is "yes"). This variable is only used
internally within the builtin.mk file.

The third section sets USE_BUILTIN.pkg and is required in all builtin.mk files.
The code in this section must make the determination whether the built-in
software is adequate to satisfy the dependencies listed in BUILDLINK_DEPENDS.
pkg. This is typically done by comparing BUILTIN_PKG.pkg against each of the
dependencies in BUILDLINK_DEPENDS.pkg. USE_BUILTIN.pkg must be set to the
correct value by the end of the builtin.mk file. Note that USE_BUILTIN.pkg may
be "yes" even if IS_BUILTIN.pkg is "no" because we may make the determination
that the built-in version of the software is similar enough to be used as a
replacement.

The last section is guarded by CHECK_BUILTIN.pkg, and includes code that uses
the value of USE_BUILTIN.pkg set in the previous section. This typically
includes, e.g., adding additional dependency restrictions and listing
additional files to symlink into ${BUILDLINK_DIR} (via BUILDLINK_FILES.pkg).

10.3.2. Global preferences for native or pkgsrc software

When building packages, it's possible to choose whether to set a global
preference for using either the built-in (native) version or the pkgsrc version
of software to satisfy a dependency. This is controlled by setting
PREFER_PKGSRC and PREFER_NATIVE. These variables take values of either "yes",
"no", or a list of packages. PREFER_PKGSRC tells pkgsrc to use the pkgsrc
versions of software, while PREFER_NATIVE tells pkgsrc to use the built-in
versions. Preferences are determined by the most specific instance of the
package in either PREFER_PKGSRC or PREFER_NATIVE. If a package is specified in
neither or in both variables, then PREFER_PKGSRC has precedence over
PREFER_NATIVE. For example, to require using pkgsrc versions of software for
all but the most basic bits on a NetBSD system, you can set:

        PREFER_PKGSRC=  yes
        PREFER_NATIVE=  getopt skey tcp_wrappers


A package must have a builtin.mk file to be listed in PREFER_NATIVE, otherwise
it is simply ignored in that list.

    11.5.1. Disabling handling of configuration files

This chapter describes the framework known as pkginstall, whose key features
are:

  * Generic installation and manipulation of directories and files outside the
    pkgsrc-handled tree, LOCALBASE.

  * Automatic handling of configuration files during installation, provided
    that packages are correctly designed.

  * Generation and installation of system startup scripts.

  * Registration of system users and groups.

  * Registration of system shells.

The following sections inspect each of the above points in detail. Note that,
in order to use any of the described functionalities, you must add the
following to your package's Makefile:

USE_PKGINSTALL=YES

You may be thinking that many of the things described here could be easily done
with simple code in the package's post-installation target (post-install). This
is incorrect, as the code in them is only executed when building from source.
Machines using binary packages could not benefit from it at all (as the code
itself could be unavailable). Therefore, the only way to achieve any of the
items described above is by means of the installation scripts, which are
automatically generated by pkginstall.

11.1. Files and directories outside the installation prefix

As you already know, the PLIST file holds a list of files and directories that
belong to a package. The names used in it are relative to the installation
prefix (${PREFIX}), which means that it cannot register files outside this
directory (absolute path names are not allowed). Despite this restriction, some
packages need to install files outside this location; e.g., under ${VARBASE} or
${PKG_SYSCONFDIR}.

The only way to achieve this is to create such files during installation time
by using the installation scripts. These scripts can run arbitrary commands, so
they have the potential to create and manage files anywhere in the filesystem.
Here is where pkginstall comes into play: it provides generic scripts to
abstract the manipulation of such files and directories based on variables set
in the package's Makefile. The rest of this section describes which these
variables are.

11.1.1. Directory manipulation

The following variables can be set to request the creation of directories
anywhere in the filesystem:

  * MAKE_DIRS and OWN_DIRS contain a list of directories that should be created
    and should attempt to be destroyed by the installation scripts. The
    difference between the two is that the latter prompts the administrator to
    remove any directories that may be left after deinstallation (because they
    were not empty), while the former does not.

  * MAKE_DIRS_PERMS and OWN_DIRS_PERMS contain a list of tuples describing
    which directories should be created and should attempt to be destroyed by
    the installation scripts. Each tuple holds the following values, separated
    by spaces: the directory name, its owner, its group and its numerical mode.
    For example:

    MAKE_DIRS_PERMS+= ${VARBASE}/foo/private ${ROOT_USER} ${ROOT_GROUP} 0700

    The difference between the two is exactly the same as their non-PERMS
    counterparts.

11.1.2. File manipulation

Creating non-empty files outside the installation prefix is tricky because the
PLIST forces all files to be inside it. To overcome this problem, the only
solution is to extract the file in the known place (i.e., inside the
installation prefix) and copy it to the appropriate location during
installation (done by the installation scripts generated by pkginstall). We
will call the former the master file in the following paragraphs, which
describe the variables that can be used to automatically and consistently
handle files outside the installation prefix:

  * CONF_FILES and SUPPORT_FILES are pairs of master and target files. During
    installation time, the master file is copied to the target one if and only
    if the latter does not exist. Upon deinstallation, the target file is
    removed provided that it was not modified by the installation.

    The difference between the two is that the latter prompts the administrator
    to remove any files that may be left after deinstallation (because they
    were not empty), while the former does not.

  * CONF_FILES_PERMS and SUPPORT_FILES_PERMS contain tuples describing master
    files as well as their target locations. For each of them, it also
    specifies their owner, their group and their numeric permissions, in this
    order. For example:

    SUPPORT_FILES_PERMS+= ${PREFIX}/share/somefile ${VARBASE}/somefile ${ROOT_USER} ${ROOT_GROUP} 0700

    The difference between the two is exactly the same as their non-PERMS
    counterparts.

11.2. Configuration files

Configuration files are special in the sense that they are installed in their
own specific directory, PKG_SYSCONFDIR, and need special treatment during
installation (most of which is automated by pkginstall). The main concept you
must bear in mind is that files marked as a configuration are automatically
copied to the right place (somewhere inside PKG_SYSCONFDIR) during installation
if and only if they didn't exist before. Similarly, they will not be removed if
they have local modifications. This ensures that administrators never loose any
custom changes they may have made.

11.2.1. How PKG_SYSCONFDIR is set

As said before, the PKG_SYSCONFDIR variable specifies where configuration files
shall be installed. Its contents are set based upon the following variables:

  * PKG_SYSCONFBASE: The configuration's root directory. Defaults to ${PREFIX}/
    etc although may be overridden by the user to point to his preferred
    location (e.g., /etc, /etc/pkg, etc.). Packages must not use it directly.

  * PKG_SYSCONFSUBDIR: A subdirectory of PKG_SYSCONFBASE under which the
    configuration files for the package being built shall be installed. The
    definition of this variable only makes sense in the package's Makefile
    (i.e., it is not user customizable).

    As an example, consider the Apache package, www/apache2, which places its
    configuration files under the httpd/ subdirectory of PKG_SYSCONFBASE. This
    should be set in the package Makefile.

  * PKG_SYSCONFVAR: Specifies the name of the variable that holds this
    package's configuration directory (if different from PKG_SYSCONFBASE). It
    defaults to PKGBASE's value, and is always prefixed with PKG_SYSCONFDIR.

  * PKG_SYSCONFDIR.${PKG_SYSCONFVAR}: Holds the directory where the
    configuration files for the package identified by PKG_SYSCONFVAR's shall be
    placed.

Based on the above variables, pkginstall determines the value of
PKG_SYSCONFDIR, which is the only variable that can be used within a package to
refer to its configuration directory. The algorithm used to set its value is
basically the following:

 1. If PKG_SYSCONFDIR.${PKG_SYSCONFVAR} is set, its value is used.

 2. If the previous variable is not defined but PKG_SYSCONFSUBDIR is set in the
    package's Makefile, the resulting value is ${PKG_SYSCONFBASE}/$
    {PKG_SYSCONFSUBDIR}.

 3. Otherwise, it is set to ${PKG_SYSCONFBASE}.

It is worth mentioning that ${PKG_SYSCONFDIR} is automatically added to
OWN_DIRS. See Section 11.1.1, "Directory manipulation" what this means.

11.2.2. Telling the software were configuration files are

Given that pkgsrc (and users!) expect configuration files to be in a known
place, you need to teach each package where shall it install its files. In some
cases you will have to patch the package Makefiles to achieve it. If you are
lucky, though, it may be as easy as passing an extra flag to the configuration
script; this is the case of GNU Autoconf generated files:

CONFIGURE_ARGS+= --sysconfdir=${PKG_SYSCONFDIR}

Note that this specifies where the package has to look for its configuration
files, not where they will be originally installed (although the difference is
never explicit, unfortunately).

11.2.3. Patching installations

As said before, pkginstall automatically handles configuration files. This
means that the packages themselves must not touch the contents of $
{PKG_SYSCONFDIR} directly. Bad news is that the software they build will, out
of the box, mess with the contents of that directory. So which is the correct
procedure to fix this issue?

You must teach the package (usually by manually patching it) to install any
configuration files under the examples hierarchy, share/examples/${PKGBASE}/.
This way, the PLIST registers them and the administrator always has the
original copies available.

Once the required configuration files are in place (i.e., under the examples
hierarchy), the pkginstall framework can use them as master copies during the
package installation to update what is in ${PKG_SYSCONFDIR}. To achieve this,
the variables CONF_FILES and CONF_FILES_PERMS are used. Check out Section
11.1.2, "File manipulation" for information about their syntax and their
purpose. Here is an example, taken from the mail/mutt package:

EGDIR=        ${PREFIX}/share/doc/mutt/samples
CONF_FILES=   ${EGDIR}/Muttrc ${PKG_SYSCONFDIR}/Muttrc

Note that the EGDIR variable is specific to that package and has no meaning
outside it.

11.2.4. Disabling handling of configuration files

The automatic copying of config files can be toggled by setting the environment
variable PKG_CONFIG prior to package installation.

11.3. System startup scripts

System startup scripts are special files because they must be installed in a
place known by the underlying OS, usually outside the installation prefix.
Therefore, the same rules described in Section 11.1, "Files and directories
outside the installation prefix" apply, and the same solutions can be used.
However, pkginstall provides a specific mechanism to handle these files, given
that they are special.

In order to provide system startup scripts, the package has to:

 1. Store the script inside ${FILESDIR}, with the .sh suffix appended.
    Considering the print/cups package as an example, it has the cupsd.sh in
    its files directory.

 2. Tell pkginstall to handle it, appending the name of the script, without its
    extension, to the RCD_SCRIPTS variable. Continuing the previous example:

    RCD_SCRIPTS+= cupsd


Once this is done, pkginstall will do the following steps for each script in an
automated fashion:

 1. Process the file found in the files directory applying all the
    substitutions described in the FILES_SUBST variable.

 2. Copy the script from the files directory to the examples hierarchy, $
    {PREFIX}/share/examples/rc.d/. Note that the master file must be explicitly
    registered in the PLIST.

 3. Add code to the installation scripts to copy the startup script from the
    examples hierarchy into the system-wide startup scripts directory.

11.3.1. Disabling handling of system startup scripts

The automatic copying of config files can be toggled by setting the environment
variable PKG_RCD_SCRIPTS prior to package installation. Note that the scripts
will be always copied inside the examples hierarchy, ${PREFIX}/share/examples/
rc.d/, no matter what the value of this variable is.

11.4. System users and groups

If a package needs to create special users and/or groups during installation,
it can do so by using the pkginstall framework.

Users can be created by adding entries to the PKG_USERS variable. Each entry
has the following syntax, which mimics /etc/passwd:

user:group[:[userid][:[descr][:[home][:shell]]]]

Only the user and group are required; everything else is optional, but the
colons must be in the right places when specifying optional bits. By default, a
new user will have home directory /nonexistent, and login shell /sbin/nologin
unless they are specified as part of the user element. Note that if the
description contains spaces, then spaces should be double backslash-escaped, as
in:

foo:foogrp::The\\ Foomister

Similarly, groups can be created using the PKG_GROUPS variable, whose syntax
is:

group[:groupid]

As before, only the group name is required; the numeric identifier is optional.

11.5. System shells

Packages that install system shells should register them in the shell database,
/etc/shells, to make things easier to the administrator. This must be done from
the installation scripts to keep binary packages working on any system.
pkginstall provides an easy way to accomplish this task.

When a package provides a shell interpreter, it has to set the PKG_SHELL
variable to its absolute file name. This will add some hooks to the
installation scripts to handle it. Consider the following example, taken from
shells/zsh:

USE_PKGINSTALL= YES
PKG_SHELL=      ${PREFIX}/bin/zsh

11.5.1. Disabling handling of configuration files

The automatic registration of shell interpreters can be disabled by the
administrator by setting the PKG_REGISTER_SHELLS environment variable to NO.

Chapter 12. Options handling

Table of Contents

12.1. Global default options
12.2. Converting packages to use bsd.options.mk

Many packages have the ability to be built to support different sets of
features. bsd.options.mk is a framework in pkgsrc that provides generic
handling of those options that determine different ways in which the packages
can be built. It's possible for the user to specify exactly which sets of
options will be built into a package or to allow a set of global default
options apply.

12.1. Global default options

Global default options are listed in PKG_DEFAULT_OPTIONS, which is a list of
the options that should be built into every package if that option is
supported. This variable should be set in /etc/mk.conf.

12.2. Converting packages to use bsd.options.mk

The following example shows how bsd.options.mk should be used by the
hypothetical ``wibble'' package, either in the package Makefile, or in a file,
e.g. options.mk, that is included by the main package Makefile.

# Global and legacy options
PKG_OPTIONS_VAR=        PKG_OPTIONS.wibble
PKG_SUPPORTED_OPTIONS=  ldap sasl
PKG_SUGGESTED_OPTIONS=  sasl
PKG_OPTION_LEGACY_VARS= WIBBLE_USE_OPENLDAP:ldap USE_SASL2:sasl

.include "../../mk/bsd.options.mk"

# Package-specific option-handling

###
### LDAP support
###
.if !empty(PKG_OPTIONS:Mldap)
.  include "../../databases/openldap/buildlink3.mk"
CONFIGURE_ARGS+=      --enable-ldap=${BUILDLINK_PREFIX.openldap}
.endif

###
### SASL authentication
###
.if !empty(PKG_OPTIONS:Msasl)
.  include "../../security/cyrus-sasl2/buildlink3.mk"
CONFIGURE_ARGS+=        --enable-sasl=${BUILDLINK_PREFIX.sasl}
.endif


The first section contains the information about which build options are
supported by the package, and any default options settings if needed.

 1. PKG_OPTIONS_VAR is the name of the make(1) variable that contains the
    options the user wishes to select. The recommended value is "PKG_OPTIONS.
    pkg" but any package-specific value may be used. This variable should be
    set in a package Makefile.

 2. PKG_SUPPORTED_OPTIONS is a list of build options supported by the package.
    This variable should be set in a package Makefile.

 3. PKG_SUGGESTED_OPTIONS is a list of build options which are enabled by
    default.

 4. ${PKG_OPTIONS_VAR} (the variable named in PKG_OPTIONS_VAR) lists the
    selected build options and overrides any default options given in
    PKG_DEFAULT_OPTIONS. If any of the options begin with a "-", then that
    option is always removed from the selected build options, e.g.

            PKG_DEFAULT_OPTIONS=    kerberos ldap sasl
            PKG_OPTIONS_VAR=        WIBBLE_OPTIONS
            WIBBLE_OPTIONS=         ${PKG_DEFAULT_OPTIONS} -sasl
            # leads to PKG_OPTIONS = kerberos ldap


    or

            PKG_OPTIONS_VAR=        WIBBLE_OPTIONS
            WIBBLE_OPTIONS=         kerberos -ldap ldap
            # leads to PKG_OPTIONS = kerberos


    This variable should be set in /etc/mk.conf.

 5. The PKG_OPTIONS_LEGACY_VARS is only needed if you are converting a package
    that had its own ad-hoc options handling to use bsd.options.mk. It converts
    global or legacy options variables into an equivalent PKG_OPTIONS.pkg
    value.

After the inclusion of bsd.options.mk, the variable PKG_OPTIONS contains the
list of the selected build options, properly filtered to remove unsupported and
duplicate options.

The remaining sections contain the logic that is specific to each option. There
should be a check for every option listed in PKG_SUPPORTED_OPTIONS, and there
should be clear documentation on what turning on the option will do in the
comments preceding each section. The correct way to check for an option is to
check whether it is listed in PKG_OPTIONS.

Chapter 13. The build process

Table of Contents

13.1. Program location
13.2. Main targets
13.3. Other helpful targets

The basic steps for building a program are always the same. First the program's
source (distfile) must be brought to the local system and then extracted. After
any patches to compile properly on NetBSD are applied, the software can be
configured, then built (usually by compiling), and finally the generated
binaries, etc. can be put into place on the system. These are exactly the steps
performed by the NetBSD package system, which is implemented as a series of
targets in a central Makefile, pkgsrc/mk/bsd.pkg.mk.

13.1. Program location

Before outlining the process performed by the NetBSD package system in the next
section, here's a brief discussion on where programs are installed, and which
variables influence this.

The automatic variable PREFIX indicates where all files of the final program
shall be installed. It is usually set to LOCALBASE (/usr/pkg), or CROSSBASE for
pkgs in the "cross" category. The value of PREFIX needs to be put into the
various places in the program's source where paths to these files are encoded.
See Section 7.3, "patches/*" and Section 14.3.1, "Shared libraries - libtool"
for more details.

When choosing which of these variables to use, follow the following rules:

  * PREFIX always points to the location where the current pkg will be
    installed. When referring to a pkg's own installation path, use "${PREFIX}
    ".

  * LOCALBASE is where all non-X11 pkgs are installed. If you need to construct
    a -I or -L argument to the compiler to find includes and libraries
    installed by another non-X11 pkg, use "${LOCALBASE}".

  * X11BASE is where the actual X11 distribution (from xsrc, etc.) is
    installed. When looking for standard X11 includes (not those installed by a
    pkg), use "${X11BASE}".

  * X11 based are special in that they may be installed in either X11BASE or
    LOCALBASE.

    Usually, X11 packages should be installed under LOCALBASE whenever
    possible. Note that you will need to include ../../mk/x11.buildlink3.mk in
    them to request the presence of X11 and to get the right compilation flags.

    Even though, there are some packages that cannot be installed under
    LOCALBASE: those that come with app-defaults files. These packages are
    special and they must be placed under X11BASE. To accomplish this, set
    either USE_X11BASE or USE_IMAKE in your package.

    Some notes: If you need to find includes or libraries installed by a pkg
    that has USE_IMAKE or USE_X11BASE in its pkg Makefile, you need to look in
    both ${X11BASE} and ${LOCALBASE}. To force installation of all X11 packages
    in LOCALBASE, the pkgtools/xpkgwedge package is enabled by default.

  * X11PREFIX should be used to refer to the installed location of an X11
    package. X11PREFIX will be set to X11BASE if xpkgwedge is not installed,
    and to LOCALBASE if xpkgwedge is installed.

  * If xpkgwedge is installed, it is possible to have some packages installed
    in X11BASE and some in LOCALBASE. To determine the prefix of an installed
    package, the EVAL_PREFIX definition can be used. It takes pairs in the
    format "DIRNAME=<package>", and the make(1) variable DIRNAME will be set to
    the prefix of the installed package <package>, or "${X11PREFIX}" if the
    package is not installed.

    This is best illustrated by example.

    The following lines are taken from pkgsrc/wm/scwm/Makefile:

    EVAL_PREFIX+=           GTKDIR=gtk+
    CONFIGURE_ARGS+=        --with-guile-prefix=${LOCALBASE}        \
                            --with-gtk-prefix="${GTKDIR}"           \
                            --enable-multibyte

    Specific defaults can be defined for the packages evaluated using
    EVAL_PREFIX, by using a definition of the form:

    GTKDIR_DEFAULT= ${LOCALBASE}

    where GTKDIR corresponds to the first definition in the EVAL_PREFIX pair.

  * Within ${PREFIX}, packages should install files according to hier(7), with
    the exception that manual pages go into ${PREFIX}/man, not ${PREFIX}/share/
    man.

13.2. Main targets

The main targets used during the build process defined in bsd.pkg.mk are:

fetch

    This will check if the file(s) given in the variables DISTFILES and
    PATCHFILES (as defined in the package's Makefile) are present on the local
    system in /usr/pkgsrc/distfiles. If they are not present, an attempt will
    be made to fetch them using commands of the form:

    ${FETCH_CMD} ${FETCH_BEFORE_ARGS} ${site}${file} ${FETCH_AFTER_ARGS}

    where ${site} varies through several possibilities in turn: first,
    MASTER_SITE_OVERRIDE is tried, then the sites specified in either
    SITES_file if defined, else MASTER_SITES or PATCH_SITES, as applies, then
    finally the value of MASTER_SITE_BACKUP. The order of all except the first
    can be optionally sorted by the user, via setting either MASTER_SORT_AWK or
    MASTER_SORT_REGEX.

checksum

    After the distfile(s) are fetched, their checksum is generated and compared
    with the checksums stored in the distinfo file. If the checksums don't
    match, the build is aborted. This is to ensure the same distfile is used
    for building, and that the distfile wasn't changed, e.g. by some malign
    force, deliberately changed distfiles on the master distribution site or
    network lossage.

extract

    When the distfiles are present on the local system, they need to be
    extracted, as they are usually in the form of some compressed archive
    format, most commonly .tar.gz.

    If only some of the distfiles need to be uncompressed, the files to be
    uncompressed should be put into EXTRACT_ONLY.

    If the distfiles are not in .tar.gz format, they can be extracted by
    setting either EXTRACT_SUFX, or EXTRACT_CMD, EXTRACT_BEFORE_ARGS and
    EXTRACT_AFTER_ARGS. In the former case, pkgsrc knows how to extract a
    number of suffixes (.tar.gz, .tgz, .tar.gz2, .tbz, .tar.Z, .tar, .shar.gz,
    .shar.bz2, .shar.Z, .shar, .Z, .bz2 and .gz; see the definition of the
    various DECOMPRESS_CMD variables bsd.pkg.mk for a complete list). Here's an
    example on how to use the other variables for a program that comes with a
    compressed shell archive whose name ends in .msg.gz:

         EXTRACT_SUFX=   .msg.gz
         EXTRACT_CMD=            zcat
         EXTRACT_BEFORE_ARGS=
         EXTRACT_AFTER_ARGS=     |sh

patch

    After extraction, all the patches named by the PATCHFILES, those present in
    the patches subdirectory of the package as well as in $LOCALPATCHES/
    $PKGPATH (e.g. /usr/local/patches/graphics/png) are applied. Patchfiles
    ending in .Z or .gz are uncompressed before they are applied, files ending
    in .orig or .rej are ignored. Any special options to patch(1) can be handed
    in PATCH_DIST_ARGS. See Section 7.3, "patches/*" for more details.

    By default patch(1) is given special args to make it fail if the patches
    apply with some lines of fuzz. Please fix (regen) the patches so that they
    apply cleanly. The rationale behind this is that patches that don't apply
    cleanly may end up being applied in the wrong place, and cause severe harm
    there.

configure

    Most pieces of software need information on the header files, system calls,
    and library routines which are available in NetBSD. This is the process
    known as configuration, and is usually automated. In most cases, a script
    is supplied with the source, and its invocation results in generation of
    header files, Makefiles, etc.

    If the program's distfile contains its own configure script, this can be
    invoked by setting HAS_CONFIGURE. If the configure script is a GNU autoconf
    script, GNU_CONFIGURE should be specified instead. In either case, any
    arguments to the configure script can be specified in the CONFIGURE_ARGS
    variable, and the configure script's name can be set in CONFIGURE_SCRIPT if
    it differs from the default "configure". Here's an example from the
    sysutils/top package:

    HAS_CONFIGURE=          yes
    CONFIGURE_SCRIPT=       Configure
    CONFIGURE_ARGS+=        netbsd13

    If the program uses an Imakefile for configuration, the appropriate steps
    can be invoked by setting USE_IMAKE to "YES". (If you only want the package
    installed in $X11PREFIX but xmkmf not being run, set USE_X11BASE instead!)

build

    Once configuration has taken place, the software will be built by invoking
    $MAKE_PROGRAM on $MAKEFILE with $BUILD_TARGET as the target to build. The
    default MAKE_PROGRAM is "gmake" if USE_TOOLS contains "gmake", "make"
    otherwise. MAKEFILE is set to "Makefile" by default, and BUILD_TARGET
    defaults to "all". Any of these variables can be set in the package's
    Makefile to change the default build process.

install

    Once the build stage has completed, the final step is to install the
    software in public directories, so users can access the programs and files.
    As in the build-target, $MAKE_PROGRAM is invoked on $MAKEFILE here, but
    with the $INSTALL_TARGET instead, the latter defaulting to "install" (plus
    "install.man", if USE_IMAKE is set).

If no target is specified, the default is "build". If a subsequent stage is
requested, all prior stages are made: e.g. make build will also perform the
equivalent of:

make fetch
make checksum
make extract
make patch
make configure
make build

13.3. Other helpful targets

pre/post-*

    For any of the main targets described in the previous section, two
    auxiliary targets exist with "pre-" and "post-" used as a prefix for the
    main target's name. These targets are invoked before and after the main
    target is called, allowing extra configuration or installation steps be
    performed from a package's Makefile, for example, which a program's
    configure script or install target omitted.

do-*

    Should one of the main targets do the wrong thing, and should there be no
    variable to fix this, you can redefine it with the do-* target. (Note that
    redefining the target itself instead of the do-* target is a bad idea, as
    the pre-* and post-* targets won't be called anymore, etc.) You will not
    usually need to do this.

reinstall

    If you did a make install and you noticed some file was not installed
    properly, you can repeat the installation with this target, which will
    ignore the "already installed" flag.

deinstall

    This target does a pkg_delete(1) in the current directory, effectively
    de-installing the package. The following variables can be used to tune the
    behaviour:

    PKG_VERBOSE

        Add a "-v" to the pkg_delete(1) command.

    DEINSTALLDEPENDS

        Remove all packages that require (depend on) the given package. This
        can be used to remove any packages that may have been pulled in by a
        given package, e.g. if make deinstall DEINSTALLDEPENDS=1 is done in
        pkgsrc/x11/kde, this is likely to remove whole KDE. Works by adding
        "-R" to the pkg_delete(1) command line.

update

    This target causes the current package to be updated to the latest version.
    The package and all depending packages first get de-installed, then current
    versions of the corresponding packages get compiled and installed. This is
    similar to manually noting which packages are currently installed, then
    performing a series of make deinstall and make install (or whatever
    UPDATE_TARGET is set to) for these packages.

    You can use the "update" target to resume package updating in case a
    previous make update was interrupted for some reason. However, in this
    case, make sure you don't call make clean or otherwise remove the list of
    dependent packages in WRKDIR. Otherwise you lose the ability to
    automatically update the current package along with the dependent packages
    you have installed.

    Resuming an interrupted make update will only work as long as the package
    tree remains unchanged. If the source code for one of the packages to be
    updated has been changed, resuming make update will most certainly fail!

    The following variables can be used either on the command line or in /etc/
    mk.conf to alter the behaviour of make update:

    UPDATE_TARGET

        Install target to recursively use for the updated package and the
        dependent packages. Defaults to DEPENDS_TARGET if set, "install"
        otherwise for make update. e.g. make update UPDATE_TARGET=package

    NOCLEAN

        Don't clean up after updating. Useful if you want to leave the work
        sources of the updated packages around for inspection or other
        purposes. Be sure you eventually clean up the source tree (see the
        "clean-update" target below) or you may run into troubles with old
        source code still lying around on your next make or make update.

    REINSTALL

        Deinstall each package before installing (making DEPENDS_TARGET). This
        may be necessary if the "clean-update" target (see below) was called
        after interrupting a running make update.

    DEPENDS_TARGET

        Allows you to disable recursion and hardcode the target for packages.
        The default is "update" for the update target, facilitating a recursive
        update of prerequisite packages. Only set DEPENDS_TARGET if you want to
        disable recursive updates. Use UPDATE_TARGET instead to just set a
        specific target for each package to be installed during make update
        (see above).

clean-update

    Clean the source tree for all packages that would get updated if make
    update was called from the current directory. This target should not be
    used if the current package (or any of its depending packages) have already
    been de-installed (e.g., after calling make update) or you may lose some
    packages you intended to update. As a rule of thumb: only use this target
    before the first time you run make update and only if you have a dirty
    package tree (e.g., if you used NOCLEAN).

    If you unsure about whether your tree is clean you can either perform a
    make clean at the top of the tree, or use the following sequence of
    commands from the directory of the package you want to update (before
    running make update for the first time, otherwise you lose all the packages
    you wanted to update!):

    # make clean-update
    # make clean CLEANDEPENDS=YES
    # make update

    The following variables can be used either on the command line or in /etc/
    mk.conf to alter the behaviour of make clean-update:

    CLEAR_DIRLIST

        After make clean, do not reconstruct the list of directories to update
        for this package. Only use this if make update successfully installed
        all packages you wanted to update. Normally, this is done automatically
        on make update, but may have been suppressed by the NOCLEAN variable
        (see above).

info

    This target invokes pkg_info(1) for the current package. You can use this
    to check which version of a package is installed.

readme

    This target generates a README.html file, which can be viewed using a
    browser such as www/mozilla or www/links. The generated files contain
    references to any packages which are in the PACKAGES directory on the local
    host. The generated files can be made to refer to URLs based on
    FTP_PKG_URL_HOST and FTP_PKG_URL_DIR. For example, if I wanted to generate
    README.html files which pointed to binary packages on the local machine, in
    the directory /usr/packages, set FTP_PKG_URL_HOST=file://localhost and
    FTP_PKG_URL_DIR=/usr/packages. The ${PACKAGES} directory and its
    subdirectories will be searched for all the binary packages.

readme-all

    Use this target to create a file README-all.html which contains a list of
    all packages currently available in the NetBSD Packages Collection,
    together with the category they belong to and a short description. This
    file is compiled from the pkgsrc/*/README.html files, so be sure to run
    this after a make readme.

cdrom-readme

    This is very much the same as the "readme" target (see above), but is to be
    used when generating a pkgsrc tree to be written to a CD-ROM. This target
    also produces README.html files, and can be made to refer to URLs based on
    CDROM_PKG_URL_HOST and CDROM_PKG_URL_DIR.

show-distfiles

    This target shows which distfiles and patchfiles are needed to build the
    package. (DISTFILES and PATCHFILES, but not patches/*)

show-downlevel

    This target shows nothing if the package is not installed. If a version of
    this package is installed, but is not the version provided in this version
    of pkgsrc, then a warning message is displayed. This target can be used to
    show which of your installed packages are downlevel, and so the old
    versions can be deleted, and the current ones added.

show-pkgsrc-dir

    This target shows the directory in the pkgsrc hierarchy from which the
    package can be built and installed. This may not be the same directory as
    the one from which the package was installed. This target is intended to be
    used by people who may wish to upgrade many packages on a single host, and
    can be invoked from the top-level pkgsrc Makefile by using the
    "show-host-specific-pkgs" target.

show-installed-depends

    This target shows which installed packages match the current package's
    DEPENDS. Useful if out of date dependencies are causing build problems.

check-shlibs

    After a package is installed, check all its binaries and (on ELF platforms)
    shared libraries to see if they find the shared libs they need. Run by
    default if PKG_DEVELOPER is set in /etc/mk.conf.

print-PLIST

    After a "make install" from a new or upgraded pkg, this prints out an
    attempt to generate a new PLIST from a find -newer work/.extract_done. An
    attempt is made to care for shared libs etc., but it is strongly
    recommended to review the result before putting it into PLIST. On upgrades,
    it's useful to diff the output of this command against an already existing
    PLIST file.

    If the package installs files via tar(1) or other methods that don't update
    file access times, be sure to add these files manually to your PLIST, as
    the "find -newer" command used by this target won't catch them!

    See Section 9.3, "Tweaking output of make print-PLIST" for more information
    on this target.

bulk-package

    Used to do bulk builds. If an appropriate binary package already exists, no
    action is taken. If not, this target will compile, install and package it
    (and it's depends, if PKG_DEPENDS is set properly. See Section 5.3.1,
    "Configuration". After creating the binary package, the sources, the
    just-installed package and it's required packages are removed, preserving
    free disk space.

    Beware that this target may deinstall all packages installed on a system!

bulk-install

    Used during bulk-installs to install required packages. If an upto-date
    binary package is available, it will be installed via pkg_add(1). If not,
    make bulk-package will be executed, but the installed binary not be
    removed.

    A binary package is considered "upto-date" to be installed via pkg_add(1)
    if:

      * None of the package's files (Makefile, ...) were modified since it was
        built.

      * None of the package's required (binary) packages were modified since it
        was built.

    Beware that this target may deinstall all packages installed on a system!

14.6. Feedback to the author

14.1. General operation

14.1.1. How to pull in variables from /etc/mk.conf

The problem with package-defined variables that can be overridden via MAKECONF
or /etc/mk.conf is that make(1) expands a variable as it is used, but evaluates
preprocessor like statements (.if, .ifdef and .ifndef) as they are read. So, to
use any variable (which may be set in /etc/mk.conf) in one of the .if*
statements, the file /etc/mk.conf must be included before that .if* statement.

Rather than have a number of ad-hoc ways of including /etc/mk.conf, should it
exist, or MAKECONF, should it exist, include the pkgsrc/mk/bsd.prefs.mk file in
the package Makefile before any preprocessor-like .if, .ifdef, or .ifndef
statements:

.include "../../mk/bsd.prefs.mk"

    .if defined(USE_MENUS)
      ...
    .endif

If you wish to set the CFLAGS variable in /etc/mk.conf please make sure to use:

CFLAGS+=  -your -flags

Using CFLAGS= (i.e. without the "+") may lead to problems with packages that
need to add their own flags. Also, you may want to take a look at the devel/
cpuflags package if you're interested in optimization for the current CPU.

14.1.2. Where to install documentation

Documentation should be installed into ${PREFIX}/share/doc/${PKGBASE} or $
{PREFIX}/share/doc/${PKGNAME} (the latter includes the version number of the
package).

14.1.3. Restricted packages

Some licenses restrict how software may be re-distributed. In order to satisfy
these restrictions, the package system defines five make variables that can be
set to note these restrictions:

  * RESTRICTED

    This variable should be set whenever a restriction exists (regardless of
    its kind). Set this variable to a string containing the reason for the
    restriction.

  * NO_BIN_ON_CDROM

    Binaries may not be placed on CD-ROM. Set this variable to ${RESTRICTED}
    whenever a binary package may not be included on a CD-ROM.

  * NO_BIN_ON_FTP

    Binaries may not be placed on an FTP server. Set this variable to $
    {RESTRICTED} whenever a binary package may not not be made available on the
    Internet.

  * NO_SRC_ON_CDROM

    Distfiles may not be placed on CD-ROM. Set this variable to ${RESTRICTED}
    if re-distribution of the source code or other distfile(s) is not allowed
    on CD-ROMs.

  * NO_SRC_ON_FTP

    Distfiles may not be placed on FTP. Set this variable to ${RESTRICTED} if
    re-distribution of the source code or other distfile(s) via the Internet is
    not allowed.

Please note that the use of NO_PACKAGE, IGNORE, NO_CDROM, or other generic make
variables to denote restrictions is deprecated, because they unconditionally
prevent users from generating binary packages!

14.1.4. Handling dependencies

Your package may depend on some other package being present - and there are
various ways of expressing this dependency. pkgsrc supports the BUILD_DEPENDS
and DEPENDS definitions, as well as dependencies via buildlink3.mk, which is
the preferred way to handle dependencies, and which uses the variables named
above. See Chapter 10, Buildlink methodology for more information.

The basic difference between the two variables is as follows: The DEPENDS
definition registers that pre-requisite in the binary package so it will be
pulled in when the binary package is later installed, whilst the BUILD_DEPENDS
definition does not, marking a dependency that is only needed for building the
package.

This means that if you only need a package present whilst you are building, it
should be noted as a BUILD_DEPENDS.

The format for a BUILD_DEPENDS and a DEPENDS definition is:

<pre-req-package-name>:../../<category>/<pre-req-package>

Please note that the "pre-req-package-name" may include any of the wildcard
version numbers recognized by pkg_info(1).

 1. If your package needs another package's binaries or libraries to build or
    run, and if that package has a buildlink3.mk file available, use it:

        .include "../../graphics/jpeg/buildlink3.mk"


 2. If your package needs to use another package to build itself and there is
    no buildlink3.mk file available, use the BUILD_DEPENDS definition:

    BUILD_DEPENDS+=  autoconf-2.13:../../devel/autoconf

 3. If your package needs a library with which to link and again there is no
    buildlink3.mk file available, this is specified using the DEPENDS
    definition. An example of this is the print/lyx package, which uses the xpm
    library, version 3.4j to build:

    DEPENDS+=       xpm-3.4j:../../graphics/xpm

    You can also use wildcards in package dependences:

    DEPENDS+=       xpm-[0-9]*:../../graphics/xpm

    Note that such wildcard dependencies are retained when creating binary
    packages. The dependency is checked when installing the binary package and
    any package which matches the pattern will be used. Wildcard dependencies
    should be used with care.

    The "-[0-9]*" should be used instead of "-*" to avoid potentially ambiguous
    matches such as "tk-postgresql" matching a "tk-*" DEPENDS.

    Wildcards can also be used to specify that a package will only build
    against a certain minimum version of a pre-requisite:

    DEPENDS+=       tiff>=3.5.4:../../graphics/tiff

    This means that the package will build against version 3.5.4 of the tiff
    library or newer. Such a dependency may be warranted if, for example, the
    API of the library has changed with version 3.5.4 and a package would not
    compile against an earlier version of tiff.

    Please note that such dependencies should only be updated if a package
    requires a newer pre-requisite, but not to denote recommendations such as
    security updates or ABI changes that do not prevent a package from building
    correctly. Such recommendations can be expressed using RECOMMENDED:

    RECOMMENDED+=   tiff>=3.6.1:../../graphics/tiff

    In addition to the above DEPENDS line, this denotes that while a package
    will build against tiff>=3.5.4, at least version 3.6.1 is recommended.
    RECOMMENDED entries will be turned into dependencies unless explicitly
    ignored (in which case a warning will be printed). Packages that are built
    with recommendations ignored may not be uploaded to ftp.NetBSD.org by
    developers and should not be used across different systems that may have
    different versions of binary packages installed.

    For security fixes, please update the package vulnerabilities file as well
    as setting RECOMMENDED, see Section 14.1.8, "Handling packages with
    security problems" for more information.

 4. If your package needs some executable to be able to run correctly and if
    there's no buildlink3.mk file, this is specified using the DEPENDS
    variable. The print/lyx package needs to be able to execute the latex
    binary from the teTeX package when it runs, and that is specified:

    DEPENDS+=        teTeX-[0-9]*:../../print/teTeX

    The comment about wildcard dependencies from previous paragraph applies
    here, too.

If your package needs files from another package to build, see the first part
of the "do-configure" target print/ghostscript5 package (it relies on the jpeg
sources being present in source form during the build):

if [ ! -e ${_PKGSRCDIR}/graphics/jpeg/${WRKDIR:T}/jpeg-6b ]; then \
          cd ${_PKGSRCDIR}/../../graphics/jpeg && ${MAKE} extract;              \
    fi

If you build any other packages that way, please make sure the working files
are deleted too when this package's working files are cleaned up. The easiest
way to do so is by adding a pre-clean target:

pre-clean:
          cd ${_PKGSRCDIR}/../../graphics/jpeg && ${MAKE} clean

Please also note the BUILD_USES_MSGFMT and BUILD_USES_GETTEXT_M4 definitions,
which are provided as convenience definitions. The former works out whether
msgfmt(1) is part of the base system, and, if it isn't, installs the devel/
gettext package. The latter adds a build dependency on either an installed
version of an older gettext package, or if it isn't, installs the devel/
gettext-m4 package.

14.1.5. Handling conflicts with other packages

Your package may conflict with other packages a user might already have
installed on his system, e.g. if your package installs the same set of files
like another package in our pkgsrc tree.

In this case you can set CONFLICTS to a space separated list of packages
(including version string) your package conflicts with.

For example x11/Xaw3d and x11/Xaw-Xpm install provide the same shared library,
thus you set in pkgsrc/x11/Xaw3d/Makefile:

CONFLICTS=      Xaw-Xpm-[0-9]*

and in pkgsrc/x11/Xaw-Xpm/Makefile:

CONFLICTS=      Xaw3d-[0-9]*

Packages will automatically conflict with other packages with the name prefix
and a different version string. "Xaw3d-1.5" e.g. will automatically conflict
with the older version "Xaw3d-1.3".

14.1.6. Packages that cannot or should not be built

There are several reasons why a package might be instructed to not build under
certain circumstances. If the package builds and runs on most platforms, the
exceptions should be noted with NOT_FOR_PLATFORM. If the package builds and
runs on a small handful of platforms, set ONLY_FOR_PLATFORM instead. If the
package should be skipped (for example, because it provides functionality
already provided by the system), set PKG_SKIP_REASON to a descriptive message.
If the package should fail because some preconditions are not met, set
PKG_FAIL_REASON to a descriptive message.

IGNORE is deprecated because it didn't provide enough information to determine
whether the build should fail.

14.1.7. Packages which should not be deleted, once installed

To ensure that a package may not be deleted, once it has been installed, the
PKG_PRESERVE definition should be set in the package Makefile. This will be
carried into any binary package that is made from this pkgsrc entry. A
"preserved" package will not be deleted using pkg_delete(1) unless the "-f"
option is used.

14.1.8. Handling packages with security problems

When a vulnerability is found, this should be noted in localsrc/security/
advisories/pkg-vulnerabilities, and after the commit of that file, it should be
copied to both /pub/NetBSD/packages/distfiles/pkg-vulnerabilities and /pub/
NetBSD/packages/distfiles/vulnerabilities on ftp.NetBSD.org using localsrc/
security/advisories/Makefile. In addition, if a buildlink3.mk file exists for
an affected package, bumping PKGREVISION and creating a corresponding
BUILDLINK_RECOMMENDED.pkg entry should be considered. See Chapter 10, Buildlink
methodology for more information about writing buildlink3.mk files and
BUILDLINK_* definitions.

Also, if the fix should be applied to the stable pkgsrc branch, be sure to
submit a pullup request!

14.1.9. How to handle compiler bugs

Some source files trigger bugs in the compiler, based on combinations of
compiler version and architecture and almost always relation to optimisation
being enabled. Common symptoms are gcc internal errors or never finishing
compiling a file.

Typically a workaround involves testing the MACHINE_ARCH and compiler version,
disabling optimisation for that file/MACHINE_ARCH/compiler combination, and
documenting it in pkgsrc/doc/HACKS. See that file for a number of examples!

14.1.10. How to handle incrementing versions when fixing an existing package

When making fixes to an existing package it can be useful to change the version
number in PKGNAME. To avoid conflicting with future versions by the original
author, a "nb1", "nb2", ... suffix can be used on package versions by setting
PKGREVISION=1 (2, ...). The "nb" is treated like a "." by the pkg tools. e.g.

  DISTNAME= foo-17.42
    PKGREVISION=  9

will result in a PKGNAME of "foo-17.42nb9".

When a new release of the package is released, the PKGREVISION should be
removed. e.g. on a new minor release of the above package, things should be
like:

DISTNAME=   foo-17.43

14.1.11. Portability of packages

One appealing feature of pkgsrc is that it runs on many different platforms. As
a result, it is important to ensure, where possible, that packages in pkgsrc
are portable. There are some particular details you should pay attention to
while working on pkgsrc.

14.1.11.1. ${INSTALL}, ${INSTALL_DATA_DIR}, ...

The BSD-compatible install supplied with some operating systems will not
perform more than one operation at a time. As such, you should call "${INSTALL}
", etc. like this:

${INSTALL_DATA_DIR} ${PREFIX}/dir1
${INSTALL_DATA_DIR} ${PREFIX}/dir2

14.2. Possible downloading issues

14.2.1. Packages whose distfiles aren't available for plain downloading

If you need to download from a dynamic URL you can set DYNAMIC_MASTER_SITES and
a make fetch will call files/getsite.sh with the name of each file to download
as an argument, expecting it to output the URL of the directory from which to
download it. graphics/ns-cult3d is an example of this usage.

If the download can't be automated, because the user must submit personal
information to apply for a password, or must pay for the source, or whatever,
you can set _FETCH_MESSAGE to a macro which displays a message explaining the
situation. _FETCH_MESSAGE must be executable shell commands, not just a
message. (Generally, it executes ${ECHO}). As of this writing, the following
packages use this: audio/realplayer, cad/simian, devel/ipv6socket, emulators/
vmware-module, fonts/acroread-jpnfont, sysutils/storage-manager, www/
ap-aolserver, www/openacs. Try to be consistent with them.

14.2.2. How to handle modified distfiles with the 'old' name

Sometimes authors of a software package make some modifications after the
software was released, and they put up a new distfile without changing the
package's version number. If a package is already in pkgsrc at that time, the
checksum will no longer match. The contents of the new distfile should be
compared against the old one before changing anything, to make sure the
distfile was really updated on purpose, and that no trojan horse or so crept
in. Then, the correct way to work around this is to set DIST_SUBDIR to a unique
directory name, usually based on PKGNAME_NOREV. In case this happens more
often, PKGNAME can be used (thus including the nbX suffix) or a date stamp can
be appended, like ${PKGNAME_NOREV}-YYYYMMDD. Do not forget regenerating the
distinfo file after that, since it contains the DIST_SUBDIR path in the
filenames. Furthermore, a mail to the package's authors seems appropriate
telling them that changing distfiles after releases without changing the file
names is not good practice.

14.3. Configuration gotchas

14.3.1. Shared libraries - libtool

pkgsrc supports many different machines, with different object formats like
a.out and ELF, and varying abilities to do shared library and dynamic loading
at all. To accompany this, varying commands and options have to be passed to
the compiler, linker, etc. to get the Right Thing, which can be pretty annoying
especially if you don't have all the machines at your hand to test things. The
devel/libtool pkg can help here, as it just "knows" how to build both static
and dynamic libraries from a set of source files, thus being platform
independent.

Here's how to use libtool in a pkg in seven simple steps:

 1. Add USE_LIBTOOL=yes to the package Makefile.

 2. For library objects, use "${LIBTOOL} --mode=compile ${CC}" in place of "$
    {CC}". You could even add it to the definition of CC, if only libraries are
    being built in a given Makefile. This one command will build both PIC and
    non-PIC library objects, so you need not have separate shared and
    non-shared library rules.

 3. For the linking of the library, remove any "ar", "ranlib", and "ld
    -Bshareable" commands, and instead use:

    ${LIBTOOL} --mode=link ${CC} -o ${.TARGET:.a=.la} ${OBJS:.o=.lo} -rpath ${PREFIX}/lib -version-info major:minor

    Note that the library is changed to have a .la extension, and the objects
    are changed to have a .lo extension. Change OBJS as necessary. This
    automatically creates all of the .a, .so.major.minor, and ELF symlinks (if
    necessary) in the build directory. Be sure to include "-version-info",
    especially when major and minor are zero, as libtool will otherwise strip
    off the shared library version.

    From the libtool manual:

         So, libtool library versions are described by three integers:

    CURRENT
           The most recent interface number that this library implements.

    REVISION
           The implementation number of the CURRENT interface.

    AGE
           The difference between the newest and oldest interfaces that this
           library implements.  In other words, the library implements all the
           interface numbers in the range from number `CURRENT - AGE' to
           `CURRENT'.

         If two libraries have identical CURRENT and AGE numbers, then the
    dynamic linker chooses the library with the greater REVISION number.

    The "-release" option will produce different results for a.out and ELF
    (excluding symlinks) in only one case. An ELF library of the form
    "libfoo-release.so.x.y" will have a symlink of "libfoo.so.x.y" on an a.out
    platform. This is handled automatically.

    The "-rpath argument" is the install directory of the library being built.

    In the PLIST, include only the .la file, the other files will be added
    automatically.

 4. When linking shared object (.so) files, i.e. files that are loaded via
    dlopen(3), NOT shared libraries, use "-module -avoid-version" to prevent
    them getting version tacked on.

    The PLIST file gets the foo.so entry.

 5. When linking programs that depend on these libraries before they are
    installed, preface the cc(1) or ld(1) line with "${LIBTOOL} --mode=link",
    and it will find the correct libraries (static or shared), but please be
    aware that libtool will not allow you to specify a relative path in -L
    (such as "-L../somelib"), because it expects you to change that argument to
    be the .la file. e.g.

    ${LIBTOOL} --mode=link ${CC} -o someprog -L../somelib -lsomelib

    should be changed to:

    ${LIBTOOL} --mode=link ${CC} -o someprog ../somelib/somelib.la

    and it will do the right thing with the libraries.

 6. When installing libraries, preface the install(1) or cp(1) command with "$
    {LIBTOOL} --mode=install", and change the library name to .la. e.g.

    ${LIBTOOL} --mode=install ${BSD_INSTALL_DATA} ${SOMELIB:.a=.la} ${PREFIX}/lib

    This will install the static .a, shared library, any needed symlinks, and
    run ldconfig(8).

 7. In your PLIST, include only the .la file (this is a change from previous
    behaviour).

14.3.2. Using libtool on GNU packages that already support libtool

Add USE_LIBTOOL=yes to the package Makefile. This will override the package's
own libtool in most cases. For older libtool using packages, libtool is made by
ltconfig script during the do-configure step; you can check the libtool script
location by doing make configure; find work*/ -name libtool.

LIBTOOL_OVERRIDE specifies which libtool scripts, relative to WRKSRC, to
override. By default, it is set to "libtool */libtool */*/libtool". If this
does not match the location of the package's libtool script(s), set it as
appropriate.

If you do not need *.a static libraries built and installed, then use
SHLIBTOOL_OVERRIDE instead.

If your package makes use of the platform independent library for loading
dynamic shared objects, that comes with libtool (libltdl), you should include
devel/libltdl/buildlink3.mk.

Some packages use libtool incorrectly so that the package may not work or build
in some circumstances. Some of the more common errors are:

  * The inclusion of a shared object (-module) as a dependent library in an
    executable or library. This in itself isn't a problem if one of two things
    has been done:

     1. The shared object is named correctly, i.e. libfoo.la, not foo.la

     2. The -dlopen option is used when linking an executable.

  * The use of libltdl without the correct calls to initialisation routines.
    The function lt_dlinit() should be called and the macro
    LTDL_SET_PRELOADED_SYMBOLS included in executables.

14.3.3. GNU Autoconf/Automake

If a package needs GNU autoconf or automake to be executed to regenerate the
configure script and Makefile.in makefile templates, then they should be
executed in a pre-configure target.

For packages that need only autoconf:

AUTOCONF_REQD=    2.50     # if default version is not good enough
USE_TOOLS+=     autoconf   # use "autoconf213" for autoconf-2.13
...

pre-configure:
          cd ${WRKSRC}; autoconf

...

and for packages that need automake and autoconf:

AUTOMAKE_REQD=  1.7.1      # if default version is not good enough
USE_TOOLS+=     automake   # use "automake14" for autoconf-1.4
...

pre-configure:
          cd ${WRKSRC};                                           \
          aclocal; autoheader;                                    \
          automake -a --foreign -i; autoconf

...

Packages which use GNU Automake will almost certainly require GNU Make.

There are times when the configure process makes additional changes to the
generated files, which then causes the build process to try to re-execute the
automake sequence. This is prevented by touching various files in the configure
stage. If this causes problems with your package you can set AUTOMAKE_OVERRIDE=
NO in the package Makefile.

14.4. Building considerations

14.4.1. CPP defines

To port an application to NetBSD, it's usually necessary for the compiler to be
able to judge the system on which it's compiling, and we use definitions so
that the C pre-processor can do this.

To test whether you are working on a 4.4 BSD-derived system, you should use the
BSD definition, which is defined in <sys/param.h> on said systems.

#include <sys/param.h>

and then you can surround the BSD-specific parts of your package's C/C++ code
using this conditional:

#if (defined(BSD) && BSD >= 199306)
    ...
#endif

Please use the "__NetBSD__" definition sparingly - it should only apply to
features of NetBSD that are not present in other 4.4-lite derived BSDs.

14.5. Package specific actions

14.5.1. User interaction

Occasionally, packages require interaction from the user, and this can be in a
number of ways:

  * help in fetching the distfiles

  * help to configure the package before it is built

  * help during the build process

  * help during the installation of a package

The INTERACTIVE_STAGE definition is provided to notify the pkgsrc mechanism of
an interactive stage which will be needed, and this should be set in the
package's Makefile. e.g.

INTERACTIVE_STAGE= build

Multiple interactive stages can be specified:

INTERACTIVE_STAGE= configure install

14.5.2. Handling licenses

A package may underly a license which the user has or has not agreed to accept.
Usually, packages that underly well-known Open Source licenses (e.g. the GNU
Public License, GPL) won't have any special license tags added in pkgsrc which
require special action by the user of such packages, but there are quite a
number of other licenses out there that pkgsrc users may not be able to follow,
for whatever reasons. For these cases, pkgsrc contains a mechanism to note that
a package underlies a certain license, and the user has to accept the license
before the package can be installed.

Placing a certain package under a certain license works by setting the LICENSE
variable to a string identifying the license, e.g. in graphics/graphviz:

LICENSE=        graphviz-license

When trying to build, the user will get a notice that the package underlies a
license which he hasn't accepted (yet):

% make
===> graphviz-1.12 has an unacceptable license: graphviz-license.
===>     To build this package, add this line to your /etc/mk.conf:
===>     ACCEPTABLE_LICENSES+=graphviz-license
===>     To view the license, enter "/usr/bin/make show-license".
*** Error code 1

The license can be viewed with make show-license, and if it is considered
appropriate, the line printed above can be added to /etc/mk.conf to indicate
acceptance of the particular license:

ACCEPTABLE_LICENSES+=graphviz-license

When adding a package with a new license, the license text should be added to
pkgsrc/licenses for displaying. A list of known licenses can be seen in this
directory as well as by looking at the list of (commented out)
ACCEPTABLE_LICENSES variable settings in pkgsrc/mk/defaults/mk.conf.

If there is a really pressing need to accept all licenses at once, like when
trying to download or mirror all distfiles or doing a bulk build to test if all
packages in pkgsrc build, this can be done by setting _ACCEPTABLE=yes.

14.5.3. Installing score files

Certain packages, most of them in the games category, install a score file that
allows all users on the system to record their highscores. In order for this to
work, the binaries need to be installed setgid and the score files owned by the
appropriate group and/or owner (traditionally the "games" user/group). The
following variables, documented in more detail in mk/defaults/mk.conf, control
this behaviour: SETGIDGAME, GAMEDATAMODE, GAMEGRP, GAMEMODE, GAMEOWN.

Note that per default, setgid installation of games is disabled; setting
SETGIDGAME=YES will set all the other variables accordingly.

A package should therefor never hard code file ownership or access permissions
but rely on INSTALL_GAME and INSTALL_GAME_DATA to set these correctly.

14.5.4. Packages containing perl scripts

If your package contains interpreted perl scripts, set REPLACE_PERL to ensure
that the proper interpreter path is set. REPLACE_PERL should contain a list of
scripts, relative to WRKSRC, that you want adjusted.

14.5.5. Packages with hardcoded paths to other interpreters

Your package may also contain scripts with hardcoded paths to other
interpreters besides (or as well as) perl. To correct the full pathname to the
script interpreter, you need to set the following definitions in your Makefile
(we shall use tclsh in this example):

  REPLACE_INTERPRETER+=     tcl
    _REPLACE.tcl.old=     .*/bin/tclsh
    _REPLACE.tcl.new=     ${PREFIX}/bin/tclsh
    _REPLACE_FILES.tcl=   ...list of tcl scripts which need to be fixed,
                          relative to ${WRKSRC}, just as in REPLACE_PERL

14.5.6. Packages installing perl modules

Makefiles of packages providing perl5 modules should include the Makefile
fragment ../../lang/perl5/module.mk. It provides a do-configure target for the
standard perl configuration for such modules as well as various hooks to tune
this configuration. See comments in this file for details.

Perl5 modules will install into different places depending on the version of
perl used during the build process. To address this, pkgsrc will append lines
to the PLIST corresponding to the files listed in the installed .packlist file
generated by most perl5 modules. This is invoked by defining PERL5_PACKLIST to
a space-separated list of paths to packlist files, e.g.:

PERL5_PACKLIST=   ${PERL5_SITEARCH}/auto/Pg/.packlist

The variables PERL5_SITELIB, PERL5_SITEARCH, and PERL5_ARCHLIB represent the
three locations in which perl5 modules may be installed, and may be used by
perl5 packages that don't have a packlist. These three variables are also
substituted for in the PLIST.

14.5.7. Packages installing info files

Some packages install info files or use the "makeinfo" or "install-info"
commands. Each of the info files:

  * is considered to be installed in the directory ${PREFIX}/${INFO_DIR},

  * is registered in the Info directory file ${PREFIX}/${INFO_DIR}/dir,

  * and must be listed as a filename in the INFO_FILES variable in the package
    Makefile.

INFO_DIR defaults to "info" and can be overridden in the package Makefile.
INSTALL and DEINSTALL scripts will be generated to handle registration of the
info files in the Info directory file. The "install-info" command used for the
info files registration is either provided by the system, or by a special
purpose package automatically added as dependency if needed.

A package which needs the "makeinfo" command at build time must define the
variable USE_MAKEINFO in its Makefile. If a minimum version of the "makeinfo"
command is needed it should be noted with the TEXINFO_REQD variable in the
package Makefile. By default, a minimum version of 3.12 is required. If the
system does not provide a makeinfo command or if it does not match the required
minimum, a build dependency on the devel/gtexinfo package will be added
automatically.

The build and installation process of the software provided by the package
should not use the install-info command as the registration of info files is
the task of the package INSTALL script, and it must use the appropriate
makeinfo command.

To achieve this goal the pkgsrc infrastructure creates overriding scripts for
the install-info and makeinfo commands in a directory listed early in PATH.

The script overriding install-info has no effect except the logging of a
message. The script overriding makeinfo logs a message and according to the
value of USE_MAKEINFO and TEXINFO_REQD either run the appropriate makeinfo
command or exit on error.

14.5.8. Packages installing GConf2 data files

If a package installs .schemas or .entries files, used by GConf2, you need to
take some extra steps to make sure they get registered in the database:

 1. Include ../../devel/GConf2/schemas.mk instead of its buildlink3.mk file.
    This takes care of rebuilding the GConf2 database at installation and
    deinstallation time, and tells the package where to install GConf2 data
    files using some standard configure arguments. It also disallows any access
    to the database directly from the package.

 2. Ensure that the package installs its .schemas files under ${PREFIX}/share/
    gconf/schemas. If they get installed under ${PREFIX}/etc, you will need to
    manually patch the package.

 3. Check the PLIST and remove any entries under the etc/gconf directory, as
    they will be handled automatically. See Section 6.14, "How do I change the
    location of configuration files?" for more information.

 4. Define the GCONF2_SCHEMAS variable in your Makefile with a list of all
    .schemas files installed by the package, if any. Names must not contain any
    directories in them.

 5. Define the GCONF2_ENTRIES variable in your Makefile with a list of all
    .entries files installed by the package, if any. Names must not contain any
    directories in them.

14.5.9. Packages installing scrollkeeper data files

If a package installs .omf files, used by scrollkeeper, you need to take some
extra steps to make sure they get registered in the database:

 1. Include ../../textproc/scrollkeeper/omf.mk instead of its buildlink3.mk
    file. This takes care of rebuilding the scrollkeeper database at
    installation and deinstallation time, and disallows any access to it
    directly from the package.

 2. Check the PLIST and remove any entries under the libdata/scrollkeeper
    directory, as they will be handled automatically.

 3. Remove the share/omf directory from the PLIST. It will be handled by
    scrollkeeper.

14.5.10. Packages installing X11 fonts

If a package installs font files, you will need to rebuild the fonts database
in the directory where they get installed at installation and deinstallation
time. This can be automatically done by using mk/fonts.mk, which you need to
include in your Makefile.

When the file is included, you can list the directories where fonts are
installed in the FONTS_type_DIRS variables, where type can be one of "TTF",
"TYPE1" or "X11". Also make sure that the database file fonts.dir is not listed
in the PLIST.

Note that you should not create new directories for fonts; instead use the
standard ones to avoid that the user needs to manually configure his X server
to find them.

14.5.11. Packages installing GTK2 modules

If a package installs gtk2 immodules or loaders, you need to take some extra
steps to get them registered in the GTK2 database properly:

 1. Include ../../x11/gtk2/modules.mk instead of its buildlink3.mk file. This
    takes care of rebuilding the database at installation and deinstallation
    time.

 2. Set GTK2_IMMODULES=YES if your package installs GTK2 immodules.

 3. Set GTK2_LOADERS=YES if your package installs GTK2 loaders.

 4. Patch the package to not touch any of the gtk2 databases directly. These
    are:

      * libdata/gtk-2.0/gdk-pixbuf.loaders

      * libdata/gtk-2.0/gtk.immodules

 5. Check the PLIST and remove any entries under the libdata/gtk-2.0 directory,
    as they will be handled automatically.

14.5.12. Packages installing SGML or XML data

If a package installs SGML or XML data files that need to be registered in
system-wide catalogs (like DTDs, sub-catalogs, etc.), you need to take some
extra steps:

 1. Include ../../textproc/xmlcatmgr/catalogs.mk in your Makefile, which takes
    care of registering those files in system-wide catalogs at installation and
    deinstallation time.

 2. Set SGML_CATALOGS to the full path of any SGML catalogs installed by the
    package.

 3. Set XML_CATALOGS to the full path of any XML catalogs installed by the
    package.

 4. Set SGML_ENTRIES to individual entries to be added to the SGML catalog.
    These come in groups of three strings; see xmlcatmgr(1) for more
    information (specifically, arguments recognized by the 'add' action). Note
    that you will normally not use this variable.

 5. Set XML_ENTRIES to individual entries to be added to the XML catalog. These
    come in groups of three strings; see xmlcatmgr(1) for more information
    (specifically, arguments recognized by the 'add' action). Note that you
    will normally not use this variable.

14.5.13. Packages installing extensions to the MIME database

If a package provides extensions to the MIME database by installing .xml files
inside ${PREFIX}/share/mime/packages, you need to take some extra steps to
ensure that the database is kept consistent with respect to these new files:

 1. Include ../../databases/shared-mime-info/mimedb.mk (avoid using the
    buildlink3.mk file from this same directory, which is reserved for
    inclusion from other buildlink3.mk files). It takes care of rebuilding the
    MIME database at installation and deinstallation time, and disallows any
    access to it directly from the package.

 2. Check the PLIST and remove any entries under the share/mime directory,
    except for files saved under share/mime/packages. The former are handled
    automatically by the update-mime-database program, but the later are
    package-dependent and must be removed by the package that installed them in
    the first place.

 3. Remove any share/mime/* directories from the PLIST. They will be handled by
    the shared-mime-info package.

14.5.14. Packages using intltool

If a package uses intltool during its build, include the ../../textproc/
intltool/buildlink3.mk file, which forces it to use the intltool package
provided by pkgsrc, instead of the one bundled with the distribution file.

This tracks intltool's build-time dependencies and uses the latest available
version; this way, the package benefits of any bug fixes that may have appeared
since it was released.

14.5.15. Packages installing startup scripts

If a package contains a rc.d script, it won't be copied into the startup
directory by default, but you can enable it, by adding the option
PKG_RCD_SCRIPTS=YES in /etc/mk.conf. This option will copy the scripts into /
etc/rc.d when a package is installed, and it will automatically remove the
scripts when the package is deinstalled.

14.6. Feedback to the author

If you have found any bugs in the package you make available, if you had to do
special steps to make it run under NetBSD or if you enhanced the software in
various other ways, be sure to report these changes back to the original author
of the program! With that kind of support, the next release of the program can
incorporate these fixes, and people not using the NetBSD packages system can
win from your efforts.

Support the idea of free software!

Chapter 15. Debugging

To check out all the gotchas when building a package, here are the steps that I
do in order to get a package working. Please note this is basically the same as
what was explained in the previous sections, only with some debugging aids.

  * Be sure to set PKG_DEVELOPER=1 in /etc/mk.conf

  * Install pkgtools/url2pkg, create a directory for a new package, change into
    it, then run url2pkg:

    % mkdir /usr/pkgsrc/category/examplepkg
    % cd /usr/pkgsrc/category/examplepkg
    % url2pkg http://www.example.com/path/to/distfile.tar.gz

  * Edit the Makefile as requested.

  * Fill in the DESCR file

  * Run make configure

  * Add any dependencies glimpsed from documentation and the configure step to
    the package's Makefile.

  * Make the package compile, doing multiple rounds of

    % make
    % pkgvi ${WRKSRC}/some/file/that/does/not/compile
    % mkpatches
    % patchdiff
    % mv ${WRKDIR}/.newpatches/* patches
    % make mps
    % make clean

    Doing as non-root user will ensure that no files are modified that
    shouldn't be, especially during the build phase. mkpatches, patchdiff and
    pkgvi are from the pkgtools/pkgdiff package.

  * Look at the Makefile, fix if necessary; see Section 7.1, "Makefile".

  * Generate a PLIST:

    # make install
    # make print-PLIST >PLIST
    # make deinstall
    # make install
    # make deinstall

    You usually need to be root to do this. Look if there are any files left:

    # make print-PLIST

    If this reveals any files that are missing in PLIST, add them.

  * Now that the PLIST is OK, install the package again and make a binary
    package:

    # make reinstall
    # make package

  * Delete the installed package:

    # pkg_delete blub

  * Repeat the above make print-PLIST command, which shouldn't find anything
    now:

    # make print-PLIST

  * Reinstall the binary package:

    # pkgadd .../blub.tgz

  * Play with it. Make sure everything works.

  * Run pkglint from pkgtools/pkglint, and fix the problems it reports:

    # pkglint

  * Submit (or commit, if you have cvs access); see Chapter 16, Submitting and
    Committing.

Chapter 16. Submitting and Committing

Table of Contents

16.1. Submitting your packages
16.2. Committing: Importing a package into CVS
16.3. Updating a package to a newer version
16.4. Moving a package in pkgsrc

16.1. Submitting your packages

You have to separate between binary and "normal" (source) packages here:

  * precompiled binary packages

    Our policy is that we accept binaries only from pkgsrc developers to
    guarantee that the packages don't contain any trojan horses etc. This is
    not to annoy anyone but rather to protect our users! You're still free to
    put up your home-made binary packages and tell the world where to get them.
    NetBSD developers doing bulk builds and wanting to upload them please see
    Section 5.3.8, "Uploading results of a bulk build".

  * packages

    First, check that your package is complete, compiles and runs well; see
    Chapter 15, Debugging and the rest of this document. Next, generate an
    uuencoded gzipped tar(1) archive, preferably with all files in a single
    directory. Finally, send-pr with category "pkg", a synopsis which includes
    the package name and version number, a short description of your package
    (contents of the COMMENT variable or DESCR file are OK) and attach the
    archive to your PR.

    If you want to submit several packages, please send a separate PR for each
    one, it's easier for us to track things that way.

    Alternatively, you can also import new packages into pkgsrc-wip ("pkgsrc
    work-in-progress"); see the homepage at http://pkgsrc-wip.sourceforge.net/
    for details.

16.2. Committing: Importing a package into CVS

This section is only of interest for pkgsrc developers with write access to the
pkgsrc repository. Please remember that cvs imports files relative to the
current working directory, and that the pathname that you give the cvs import
command is so that it knows where to place the files in the repository. Newly
created packages should be imported with a vendor tag of "TNF" and a release
tag of "pkgsrc-base", e.g:

  % cd .../pkgsrc/category/pkgname
  % cvs import pkgsrc/category/pkgname TNF pkgsrc-base

Remember to move the directory from which you imported out of the way, or cvs
will complain the next time you "cvs update" your source tree. Also don't
forget to add the new package to the category's Makefile.

The commit message of the initial import should include part of the DESCR file,
so people reading the mailing lists know what the package is/does.

Please note all package updates/additions in pkgsrc/doc/CHANGES. It's very
important to keep this file up to date and conforming to the existing format,
because it will be used by scripts to automatically update pages on
www.NetBSD.org and other sites. Additionally, check the pkgsrc/doc/TODO file
and remove the entry for the package you updated, in case it was mentioned
there.

For new packages, "cvs import" is preferred to "cvs add" because the former
gets everything with a single command, and provides a consistent tag.

16.3. Updating a package to a newer version

Please always put a concise, appropriate and relevant summary of the changes
between old and new versions into the commit log when updating a package. There
are various reasons for this:

  * A URL is volatile, and can change over time. It may go away completely or
    its information may be overwritten by newer information.

  * Having the change information between old and new versions in our CVS
    repository is very useful for people who use either cvs or anoncvs.

  * Having the change information between old and new versions in our CVS
    repository is very useful for people who read the pkgsrc-changes mailing
    list, so that they can make tactical decisions about when to upgrade the
    package.

Please also recognize that, just because a new version of a package has been
released, it should not automatically be upgraded in the CVS repository. We
prefer to be conservative in the packages that are included in pkgsrc -
development or beta packages are not really the best thing for most places in
which pkgsrc is used. Please use your judgement about what should go into
pkgsrc, and bear in mind that stability is to be preferred above new and
possibly untested features.

16.4. Moving a package in pkgsrc

 1. Make a copy of the directory somewhere else.

 2. Remove all CVS dirs.

    Alternatively to the first two steps you can also do:

    % cvs -d user@cvs.NetBSD.org:/cvsroot export -D today pkgsrc/category/package

    and use that for further work.

 3. Fix CATEGORIES and any DEPENDS paths that just did "../package" instead of
    "../../category/package".

 4. cvs import the modified package in the new place.

 5. Check if any package depends on it:

    % cd /usr/pkgsrc
    % grep /package */*/Makefile* */*/buildlink*

 6. Fix paths in packages from step 5 to point to new location.

 7. cvs rm (-f) the package at the old location.

 8. Remove from oldcategory/Makefile.

 9. Add to newcategory/Makefile.

10. Commit the changed and removed files:

    % cvs commit oldcategory/package oldcategory/Makefile newcategory/Makefile

    (and any packages from step 5, of course).

    A.1.4. Checking a package with pkglint

A.2. Steps for building, installing, packaging

We checked to find a piece of software that wasn't in the packages collection,
and picked GNU bison. Quite why someone would want to have bison when Berkeley
yacc is already present in the tree is beyond us, but it's useful for the
purposes of this exercise.

A.1. files

A.1.1. Makefile

A.1.2. DESCR

GNU version of yacc.  Can make re-entrant parsers, and numerous other
improvements.  Why you would want this when Berkeley yacc(1) is part
of the NetBSD source tree is beyond me.

A.1.3. PLIST

@comment $NetBSD$
bin/bison
man/man1/bison.1.gz
share/bison.simple
share/bison.hairy

A.1.4. Checking a package with pkglint

The NetBSD package system comes with pkgtools/pkglint which helps to check the
contents of these files. After installation it is quite easy to use, just
change to the directory of the package you wish to examine and execute pkglint:

$ pkglint
looks fine.

Depending on the supplied command line arguments (see pkglint(1)) more verbose
checks will be performed. Use e.g. pkglint -v for a very verbose check.

A.2. Steps for building, installing, packaging

Create the directory where the package lives, plus any auxiliary directories:

# cd /usr/pkgsrc/lang
# mkdir bison
# cd bison
# mkdir patches

Create Makefile, DESCR and PLIST (see Chapter 7, Package components - files,
directories and contents) then continue with fetching the distfile:

# make fetch
>> bison-1.25.tar.gz doesn't seem to exist on this system.
>> Attempting to fetch from ftp://prep.ai.mit.edu/pub/gnu//.

To create:

 1. Run bulk build, see Section 5.3, "Doing a bulk build of all packages"

 2. Upload /usr/pkgsrc/packages to

        ftp://ftp.NetBSD.org/pub/NetBSD/packages/\
            pkgsrc-2004Q4/\                         # pkgsrc-branch
            `uname -s`-`uname -r`/                  # OS & version
            `uname -p`                              # architecture


 3. If necessary, create a symlink ln -s `uname -m` `uname -p` (amiga -> m68k,
    ...)

Appendix D. Editing guidelines for the pkgsrc guide

Table of Contents

D.1. Targets
D.2. Procedure

This section contains information on editing the pkgsrc guide itself.

D.1. Targets

The pkgsrc guide's source code is stored in pkgsrc/doc/guide/files, and several
files are created from it:

  * pkgsrc/doc/pkgsrc.txt

  * pkgsrc/doc/pkgsrc.html

  * http://www.NetBSD.org/Documentation/pkgsrc/: the documentation on the
    NetBSD website will be built from pkgsrc and kept up to date on the web
    server itself. This means you must make sure that your changes haven't
    broken the build!

  * http://www.NetBSD.org/Documentation/pkgsrc/pkgsrc.pdf: PDF version of the
    pkgsrc guide.

  * http://www.NetBSD.org/Documentation/pkgsrc/pkgsrc.ps: PostScript version of
    the pkgsrc guide.

D.2. Procedure

The procedure to edit the pkgsrc guide is:

  * Make sure you have the packages needed to re-generate the pkgsrc guide (and
    other XML-based NetBSD documentation) installed. These are "netbsd-doc" for
    creating the ASCII- and HTML-version, and "netbsd-doc-print"for the
    PostScript- and PDF version. You will need both packages installed, to make
    sure documentation is consistent across all formats. The packages can be
    found in pkgsrc/meta-pkgs/netbsd-doc and pkgsrc/meta-pkgs/netbsd-doc-print.

  * Edit the XML file(s) in pkgsrc/doc/guide/files.

  * Run make extract && make do-lint in pkgsrc/doc/guide to check the XML
    syntax, and fix it if needed.

  * Run make in pkgsrc/doc/guide to build the HTML and ASCII version.

  * If all is well, run make install-doc to put the generated files into pkgsrc
    /doc.

  * cvs commit pkgsrc/doc/guide/files

  * cvs commit -m re-generate pkgsrc/doc/pkgsrc.{html,txt}

  * Until the webserver on www.NetBSD.org is really updated automatically to
    pick up changes to the pkgsrc guide automatically, also run make
    install-htdocs HTDOCSDIR=../../../htdocs (or similar, adjust HTDOCSDIR!).

  * cvs commit htdocs/Documentation/pkgsrc
