salo 4f57d48584 Update section 11.1 to advise attaching new packages as uuencoded tar 
archives for better tracking and archiving:

 11.1 Submitting your packages
 =============================

 ...

 * packages:
   First, check that your package is complete, compiles and runs well; see
   section 9 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(1) 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.

0 Intro
=======
There is a lot of software freely available for Unix based systems, which
usually runs on NetBSD, too, sometimes with some modifications. The NetBSD
packages collection incorporates any such changes necessary to make that
software run on NetBSD, and makes the installation (and re-installation) of
the software package easy by means of a single command.
The NetBSD package system is used to enable such freely available
third-party software to be built easily on NetBSD hosts. 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.
Both the NetBSD packages collection and the NetBSD package system are
derived from FreeBSD.
0.1 Overview
============
This document is divided into two parts. The first, "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 copy using the NetBSD package system. The
second part, "Package Constructor'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.
0.2 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 the NetBSD package
system. Packages are traditionally stored under /usr/pkgsrc.
* The NetBSD package system:
This is the part of the NetBSD operating system handling 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 freely available 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 stored below /usr/pkgsrc/distfiles.
* Port:
This is the term used by FreeBSD people for what we call a package.
In NetBSD terminology, "port" refers to a different architecture.
* Precompiled (binary) package:
A set of binaries built by the NetBSD package system from a distfile
using the NetBSD package system 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 generated in
/usr/pkgsrc/packages by the NetBSD package system; 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.
* NetBSD RCS IDs:
Some files in a package contain RCS IDs to reflect which version of
that file this is (inserted automatically by cvs). These IDs are used
in several examples within this document, but as this document itself
is managed by CVS, it can't list the RCS IDs in plaintext. Instead, the
$s are written as <$>, resulting in <$>NetBSD<$> and <$>Id<$>.
0.3 Typography
==============
Right now this document is written in plain ASCII text, and there's not
much typography applied here. It's being moved to DocBook.
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.
====================
Part I: User's Guide
====================
1 Installing a precompiled binary package
=========================================
This section describes how to find, retrieve and install a precompiled
binary package that someone else already prepared for your type of machine.
1.1 Where to get
================
Precompiled packages are stored on ftp.netbsd.org and its mirrors in the
directory /pub/NetBSD/packages for anon FTP access. Please pick the right
subdirectory there as indicated by "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 CDROM's documentation for the exact location!
1.2 How to use
==============
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/<OS Ver>/<arch>/All/package.tgz
If there is any doubt, the uname utility can be used to determine the
<OS Ver>, and <arch> by running "uname -rp".
Also note that any prerequisite packages needed to run the package in
question will be installed, too, assuming they are present where you install
from.
After you've installed packages, be sure to have /usr/pkg/bin in your $PATH
so you can actually start the just installed program.
1.3 A word of warning
=====================
Please pay very careful attention to the warnings expressed in that 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.
2 Installing by Building
========================
This assumes that the package is already part of the NetBSD package system.
If it is not, then you are advised to read part II of this document,
"Package Constructor's Guide".
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.
2.2 Where to get pkgsrc
=======================
There are three ways to get pkgsrc. Either as a tar file, via SUP, or
via CVS. All three ways are described here.
To get the package source going, you need to get the pkgsrc.tar.gz file
from ftp://ftp.netbsd.org/pub/NetBSD-current/tar_files/pkgsrc.tar.gz and
unpack it into /usr/pkgsrc.
As an alternative, you can get pkgsrc via the Software Update Protocol,
SUP. To do so, make sure your supfile has a line saying "release=pkgsrc" in
it, see the examples in /usr/share/examples/supfiles, and that the
directory /usr/pkgsrc does exist. Then, simply start "sup -v
/path/to/your/supfile".
To get pkgsrc via CVS, make sure you have cvs installed. If not present on
your system, it can be found as precompiled binary on ftp.netbsd.org.
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.
2.3 Fetching distfiles
======================
There is one gotcha: The distribution file (i.e. the unmodified source)
must exist on your system for the packages system to be able to build it.
If it does not, then ftp(1) is used to fetch the distribution files
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/bsd.pkg.defaults.mk 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.
2.4 How to build and install
============================
Assuming that the distfile has been fetched (see previous section), become
root and change into the relevant directory. Then you can type
% make
at the shell prompt to build the various components of the package, and
# make install
at the shell prompt to install the various components into the correct
places on your system.
Taking the top system utility as an example, we can install it on our
system by building as shown in appendix A.1.
The program is installed under the default root of the packages tree -
/usr/pkg. Should this not conform to your tastes, simply 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 root 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, for example, 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.
There is, of course, one exception to this - X11 packages are traditionally
installed in the X11 tree. The definition used to identify the root of the
X11 tree is the X11BASE definition.
It is possible to install X11 packages in the LOCALBASE tree, for
which you must install the xpkgwedge package
(pkgsrc/pkgtools/xpkgwedge) - see section 7.1 for further details.
Some packages look in /etc/mk.conf to alter some configuration options
at build time. Have a look at pkgsrc/mk/bsd.pkg.defaults.mk to
get an overview of what will be set there by default. Environment
variables such as LOCALBASE, and X11BASE 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. As a worked 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.
make show-var VARNAME=DISTFILES
will show the expansion of the make(1) variable "DISTFILES".
If you want to de-install and re-install a binary package that you've
created (see next section), that you put into pkgsrc/packages manually or
that's located on a remote FTP server, you can use the the "bin-install"
target. This target will install a binary package - if available - via
pkg_add, and do a "make package" else. The list of remote FTP sites
searched is kept in the variable BINPKG_SITE, which defaults to
ftp.netbsd.org. Any flags that should be added to pkg_add(8) can be put
into BIN_INSTALL_FLAGS. See pkgsrc/mk/bsd.pkg.defaults.mk for more details.
A final word of warning: If you setup a system that has a non-standard
setting for LOCALBASE (or X11BASE, for that matter), 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.
3 Making precompiled packages
=============================
3.1 Packaging a single package
==============================
Once you have built and installed the package as mentioned above, you can
build it into a "binary package" - you might want to do this so that you
can use the binaries you have just built on another NetBSD system, or to
provide a simple means for others to use your binary package instead of
wasting CPU time - this is done by changing to the appropriate directory in
the pkgsrc tree, and typing the command
# make package
at the shell prompt. This will build and install your package (if not
already done), and then construct a binary package out of the results so
that you can use the pkg_* tools to manipulate this. The binary package is
stored under /usr/pkgsrc/packages, it's in the form of a gzipped file at
the present time. See appendix A.2 for a continuation of the above top
example.
Please see the "submitting" section later in this document on how to submit
such a binary package.
3.2 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 your system! Having a 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.
3.2.1 Configuration
===================
3.2.1.1 /etc/mk.conf
====================
You may want to set things in /etc/mk.conf. Look at
pkgsrc/mk/bsd.pkg.defaults.mk for details of the default settings.
You will want to make sure that ACCEPTABLE_LICENSES meet your local
policy:
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
If you wish to use xpkgwedge for the entire build, then add:
BULK_PREREQ+= pkgtools/xpkgwedge
Other packages which must be installed during the bulk build to modify the
build behaviour may be added to the BULK_PREREQ variable. Note that currently
the only package for which BULK_PREREQ makes sense is xpkgwedge.
3.2.1.2 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, where your pkgsrc is located and
which user to su(8) to to do a 'cvs update'.
3.2.1.3 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 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/games/crafty-book-enormous/$BROKENF
to prevent the system from trying to build a particular package
which requires nearly 3 Gb of disk space.
3.2.2 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 password file), or
(re-)install it via pkg_add 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 a OS version below 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! :)
3.2.3 Operation
===============
Make sure you don't need any of the packages still installed.
BEWARE: 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 run, you will get a summary via mail, and find
build logs in the directory specified by "FTP" in the "build.conf"
file.
3.2.4 What it does
==================
The bulk builds consist of three steps:
1. pre-build: The script updates your pkgsrc 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 depends
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.
3.2.5 Disk space requirements
=============================
Currently, roughly the following requirements are valid for
1.5/i386:
* Distfiles: 1500MB (NFS ok)
* Full set of all binaries: 1000MB (NFS ok)
* Temp space for compiling: 1500MB (local disk recommended)
For 1.5/alpha:
* Full set of all binaries: 1300MB (NFS ok)
Note that all pkgs will be de-installed as soon as they are turned into a
binary package, and that work-sources are removed, so there is no huge
demand to disk space. Afterwards, if the package is needed again, it will
be installed via pkg_add instead of building again, so there are no cycles
wasted by recompiling.
3.2.6 Setting up a sandbox for chroot'ed builds
===============================================
If you don't want all the pkgs nuked from a machine (rendering it useless
for anything but pkg compiling), there is the possibility of doing the pkg
bulk build inside a chroot environment.
The first step to do so is setting up a chroot sandbox, e.g. /usr/sandbox.
After extracting all the sets from a NetBSD installation or doing a
"make distribution DESTDIR=/usr/sandbox" in src/etc, make sure the following
items are present and properly configured:
* kernel:
cp /netbsd /usr/sandbox
* /dev/*:
cd /usr/sandbox/dev ; sh MAKEDEV all
* /etc/resolv.conf (for security/smtpd and mail):
cp /etc/resolv.conf /usr/sandbox/etc
* working(!) mail config (hostname, sendmail.cf):
cp /etc/mail/sendmail.cf /usr/sandbox/etc/mail
* /etc/localtime (for security/smtpd):
ln -sf /usr/share/zoneinfo/GMT /usr/sandbox/etc/localtime
* /usr/src (system sources, for sysutils/aperture, net/ppp-mppe):
ln -s ../disk1/cvs .
ln -s cvs/src-1.6 src
ln -s cvs/pkgsrc .
* create /var/db/pkg (not part of default install):
mkdir /usr/sandbox/var/db/pkg
* create /usr/pkg (not part of default install)
mkdir /usr/sandbox/usr/pkg
* checkout pkgsrc from cvs, into /usr/sandbox/usr/pkgsrc
cvs -d cvs.netbsd.org:/cvsroot co pkgsrc
* /usr/pkgsrc/packages & .../distfiles (point outside of sandbox)
* /etc/mk.conf, see 3.2.1.1
* adjust .../mk/bulk/build.conf
!!! Don't forget to install X !!!
If you are a developer and want to upload the resulting binary packages
to ftp.netbsd.org, make sure you are using the default X version for your
architecture and release (up to 1.6, that is 3.3.6 for all architectures).
Next thing you will want to is make sure /usr/sandbox/usr/pkgsrc contains a
fresh checkout of pkgsrc (e.g. from anoncvs). Do not mount/link this to the
copy of your pkgsrc tree you do development in, as this will likely cause
problems! Adjust .../pkgsrc/packages and .../pkgsrc/distfiles to point to
some places outside the sandbox if you want to make the files public.
Then, configure .../pkgsrc/mk/bulk/build.conf to fit your needs!
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 thrash^Wbuilding.
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).
3.3 Creating a multiple CD-ROM packages collection
==================================================
After your bulk pkgsrc 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 package pkgsrc/pkgtools/cdpack provides a simple tool for
creating the ISO 9660 images. `cdpack' arranges the packages on the CD-ROM's
in a way that keeps all the dependencies for given package on the same
CD as that package.
3.3.1 Example of cdpack
=======================
Complete documentation for cdpack is found in cdpack(1). 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. For example
# 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 with
# cdpack -x /tmp/common /usr/pkgsrc/packages/All /u2/images
and each image will contain "README", "COPYING", and "bin/myscript"
in their root directories.
====================================
Part II: Package Constructor's Guide
====================================
4 Package components - files, directories and contents
======================================================
Whenever you're preparing a package, there are a number of files involved
which are described in the following sections.
4.1 Makefile
============
Building, installation and creation of a binary package are all controlled
by the package's Makefile.
There is a Makefile for each package. This file includes the standard
bsd.pkg.mk file (referenced as "../../mk/bsd.pkg.mk"), which sets all the
definitions and actions necessary for the package to compile and install
itself. The mandatory fields are the DISTNAME which specifies the base name
of the distribution file to be downloaded from the site on the Internet,
MASTER_SITES which specifies that site, CATEGORIES which denotes the
categories into which the package falls, PKGNAME which is the name of the
package, the MAINTAINER name, and the COMMENT variable, which should
contain a one-line description of the package (the package name should not
appear, it will be added automatically). The maintainer variable is there
so that anyone who quibbles with the (always completely correct) decisions
taken by the guy who maintains the port can complain vigorously.
The MASTER_SITES may be set to one of the predefined sites:
${MASTER_SITE_XCONTRIB}
${MASTER_SITE_GNU}
${MASTER_SITE_PERL_CPAN}
${MASTER_SITE_TEX_CTAN}
${MASTER_SITE_SUNSITE}
${MASTER_SITE_GNOME}
${MASTER_SITE_SOURCEFORGE}
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:
${MASTER_SITE_GNU:=subdirectory/name/}
(Note the trailing slash after the subdirectory name.) Use of the deprecated
MASTER_SITE_SUBDIR will not work.
If the package has multiple DISTFILES or multiple PATCHFILES from different
sites, set SITES_foo to a list of URI's where file "foo" may be found. "foo"
includes the suffix, e.g.
DISTFILES=${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 audio benchmarks biology cad
chat comms converters cross databases
devel editors emulators finance fonts
games graphics ham japanese lang
mail math mbone misc net
news parallel print security shells
sysutils textproc time wm www
x11
See the NetBSD packages(7) manual page for a description of all available
options and variables.
Please pay attention to the following gotchas:
- Add MANCOMPRESSED (if not already there) if manpages are installed in
compressed form by the package; see comment in bsd.pkg.mk
- Replace /usr/local by ${PREFIX} in all files (see patches below)
- If the package installs any info files, see the section `Packages providing
info files' in this document.
- Adjust MAINTAINER to be either yourself, if you plan to maintain the
package for future updates, or set it to the default MAINTAINER
packages@netbsd.org.
- If there exists a home page for the software in question, please
add the variable HOMEPAGE right after MAINTAINER. The value of this
variable should be the URL for the home page.
- Please also set the COMMENT variable to a short description of the
package.
4.2 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 best 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 pkgsrc/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. (A good example is pkgsrc/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 4.3) 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".
4.3 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. To avoid this, use either
the "-U 2" or "-U 1" option to diff, or let the 'pkgdiff' command
from pkgsrc/pkgtools/pkgdiff help you.
If you don't want to worry about the problems in the last two paragraphs
yourself, use pkgdiff from the pkgsrc/pkgtools/pkgdiff package, which takes
care of any RCS Ids by itself.
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 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 4.2.
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 the "normal"
pkgsrc patches are applied.
4.4 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.
4.5 Optional files
==================
* INSTALL:
Shell script invoked twice during pkg_add. 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, 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}
in MESSAGE with "somevalue" before displaying the message.
4.6 work/*
==========
When you type "make" the distribution files are unpacked into this
directory. It can be removed by typing
# make clean
at the shell prompt. Also, this directory is used to keep various
timestamp files.
4.7 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 ${CP} command in the pre-configure target to achieve this.
Alternatively, you could simply diff the file against /dev/null and
use the patch mechanism to manage the creation of this file.
5 PLIST* issues
===============
This section addresses some special issues that one needs to pay attention
to when dealing with the PLIST file (or files, see below!).
5.1 Miscellaneous
=================
* NetBSD RCS Id:
Be sure to add a RCS ID line as the first thing in any PLIST file you
write:
@comment <$>NetBSD<$>
* ${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 OSes expect locale files to be either in "share" or "lib" by
default.
* 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.
* 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.${OPSYS}
* PLIST.common_end
If PLIST.${OPSYS} exists, these files are used instead of PLIST. This
allows packages which behave in this way to be handled gracefully.
Manually overriding PLIST_SRC for other more exotic uses is also
possible.
* 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 below for more
information on this target.
5.2 ${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.
5.3 ${PLIST_SUBST}
==================
Similar to MESSAGE_SUBST (see above), you can add variables and their
expansions to this variable in the following way:
PLIST_SUBST+= SOMEVAR="somevalue"
which replaces all occurrences of ${SOMEVAR} in the PLIST with "somevalue".
For the values which are replaced by default, please look in bsd.pkg.mk
(and search for PLIST_SUBST).
5.4 Perl5 modules
=================
Makefile 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, the NetBSD
packages system 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:
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.
5.5 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
6 Notes on fixes for packages
=============================
6.1 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 port using the
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.
6.2 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 "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 use instead:
${LIBTOOL} --mode=link ${CC} -o ${.TARGET:.a=.la} ${OBJS:.o=.lo} -rpath ${PREFIX}/lib -version-info major:minor
Note that the library is changed to have a .la extension, and the
objects are changed to have a .lo extension. Change OBJS as necessary.
This automatically creates all of the .a, .so.major.minor, and ELF
symlinks (if necessary) in the build directory. Be sure to include
the -version-info especially when major and minor are zero, as libtool
will otherwise strip off the shared library version.
The "-release" option will produce different results for a.out and ELF
(excluding symlinks) in only one case. An ELF library of the form
libfoo-release.so.x.y will have a symlink of libfoo.so.x.y on an a.out
platform. This is handled automatically.
The -rpath argument is the install directory of the library being built.
PLIST should include all of the .a, .la and so, .so.major and
.so.major.minor entries.
4. When linking shared object (.so) files, i.e. files that are loaded via
dlopen(3), NOT shared libraries, use "-module -avoid-version" to prevent
them getting version tacked on.
PLIST gets the foo.so entry.
5. When linking programs that depend on these libraries _before_ they are
installed, preface the cc or ld line with "${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. For example:
${LIBTOOL} --mode=link ${CC} -o someprog -L../somelib -lsomelib
should be changed to:
${LIBTOOL} --mode=link ${CC} -o someprog ../somelib/somelib.la
and it will DTRT with the libraries.
6. When installing libraries, preface the install or cp command with
"${LIBTOOL} --mode=install", and change the library name to .la. For
example:
${LIBTOOL} --mode=install ${BSD_INSTALL_DATA} ${SOMELIB:.a=.la} ${PREFIX}/lib
This will install the static .a, shared library, any needed symlinks,
and run "ldconfig."
7. In your PLIST, include all of the .a, .la, and so, .so.major and
.so.major.minor files (this is a change from the previous behaviour).
6.3 Using libtool on GNU packages that already support libtool
==============================================================
Add USE_LIBTOOL=yes and LTCONFIG_OVERRIDE=${WRKSRC}/ltconfig to the package
Makefile as the quick way to bypass the pkg's own libtool. The pkg's own
libtool is made by ltconfig script at do-configure target. If USE_LIBTOOL
and LTCONFIG_OVERRIDE are defined, the specified ltconfig is overridden,
using the pkgsrc/devel/libtool instead of the pkg's own libtool. For newer
versions of libtool (without ltconfig) it may be necessary to use
LIBTOOL_OVERRIDE=${WRKSRC}/libtool instead.
If your package makes use of the platform independent library for loading
dynamic shared objects, that comes with libtool (libltdl), you should
include the libtool buildlink2.mk (and set USE_BUILDLINK2 to YES).
Some packages use libtool incorrectly so that the package may not work or
build in some circumstances. Some 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 and 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.
6.4 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. Two makefile fragments are provided
in pkgsrc/mk/autoconf.mk and pkgsrc/mk/automake.mk to help dealing with
these tools. See comments in these files for details.
For packages that need only autoconf:
AUTOCONF_REQD= 2.50 # if default version is not good enough
...
pre-configure:
cd ${WRKSRC}; ${AUTOCONF}
...
.include "../../mk/autoconf.mk"
and for packages that need automake and autoconf:
AUTOMAKE_REQD= 1.7.1 # if default version is not good enough
...
pre-configure:
cd ${WRKSRC}; \
${ACLOCAL}; \
${AUTOHEADER}; \
${AUTOMAKE} -a --foreign -i; \
${AUTOCONF}
...
.include "../mk/automake.mk"
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 to NO in the package Makefile.
6.5 Package configuration files
===============================
Packages should be taught to look for their configuration files in
${PKG_SYSCONFDIR}, which is passed through to the configure and build
processes. PKG_SYSCONFDIR may be customized in various ways by setting
other make variables:
* PKG_SYSCONFBASE is the main config directory under which all package
configuration files are to be found. This defaults to ${PREFIX}/etc, but
may be overridden in /etc/mk.conf.
* PKG_SYSCONFSUBDIR is the subdirectory of PKG_SYSCONFBASE under which the
configuration files for a particular package may be found, e.g. the
Apache configuration files may all be found under the "httpd" subdirectory
of ${PKG_SYSCONFBASE}. This is meant to be set in a package Makefile.
* By default PKG_SYSCONFDIR=${PKG_SYSCONFBASE}/${PKG_SYSCONFSUBDIR}, but
the default may be overridden by setting PKG_SYSCONFDIR.${PKG_SYSCONFVAR}
for a particular package, where PKG_SYSCONFVAR defaults to ${PKGBASE}.
This is not meant to be set by a package Makefile, but is reserved for
users who wish to override the PKG_SYSCONFDIR setting for a particular
package with a special location.
The only variables that users should customize are PKG_SYSCONFBASE and
PKG_SYSCONFDIR.${PKG_SYSCONFVAR}. Users will typically want to set
PKG_SYSCONFBASE to /etc, or to accept the default location of ${PREFIX}/etc.
6.6 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!
7 The build process
===================
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.
7.1 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, though its value becomes
that of $X11BASE if USE_IMAKE or USE_X11BASE is set. The value ${PREFIX}
needs to be put into the various places in the program's source where paths
to these files are encoded; see sections 4.3 and 6.2 for details on this.
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 pkgs are special in that they may be installed in either
X11BASE or LOCALBASE. To install X11 packages in LOCALBASE, simply
install the xpkgwedge package (pkgsrc/pkgtools/xpkgwedge).
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 use _both_
${X11BASE} and ${LOCALBASE}.
* ${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.
7.2 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 EXTRACT_CMD.
* 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 4.3 for more
details.
By default patch is given special args to make it fail if the
patches with some lines of fuzz. Please fix (regen) the patches
so that they apply cleanly. The rationale behind this is that
patches that 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".
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 can be built on
NetBSD by invoking $MAKE_PROGRAM on $MAKEFILE with $ALL_TARGET as
the target to build. The default MAKE_PROGRAM is "gmake" if
USE_GMAKE is set, "make" otherwise. MAKEFILE is set to "Makefile"
by default, and ALL_TARGET defaults to "all". Any of these
variables can be set to change the default build process.
* install:
Once the build stage has completed, the final step is to install
the software in public directories, for users. 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
7.3 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, for example, which 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 either on the command line or in /etc/mk.conf 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 a "-R" to the pkg_delete 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 call "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" for the current package. You can use this
e.g. 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 navigator (pkgsrc/www/navigator) or lynx
(pkgsrc/www/lynx). 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
target "show-host-specific-pkgs"
* show-installed-depends:
This target shows which installed packages match the current package's
DEPENDS. Useful if out of date DEPENDS 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 'find -newer' won't catch them!
* 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 3.2.1). After creating the binary package, the sources, the
just-installed package and it's required packages are removed,
preserving free disk space.
* bulk-install:
Used during bulk-installs to install required packages. If an
appropriate binary package is available, it will be installed via
pkg_add. If not, "make bulk-package" will be executed, but the installed
binary not be removed. A binary package is "appropriate" to be installed
via pkg_add 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
8 buildlink2 methodology
========================
"buildlink2" is a pkgsrc framework 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 into ${BUILDLINK_DIR}.
This normalizes the environment in which a package is built so that the
package may be built consistently despite what may other software may
installed. Please refer to pkgsrc/mk/buildlink2/buildlink2.txt for some
FAQs and answers regarding buildlink2, and to pkgsrc/mk/buildlink2/README
for a description of how buildlink2 is implemented in pkgsrc.
8.1 Converting packages to use buildlink2
=========================================
The process of converting packages to use the buildlink2 framework is
fairly straightforward. The package Makefile must define USE_BUILDLINK2.
If a dependency on a particular package, e.g. foo, is required for its
libraries and headers, then we replace:
DEPENDS+= foo>=1.1.0:../../category/foo
with
.include "../../category/foo/buildlink2.mk"
There are several buildlink2.mk files in pkgsrc/mk that handle special
package issues:
* motif.buildlink2.mk checks for a system-provided Motif installation
or adds a dependency on x11/lesstif or x11/openmotif;
* ossaudio.buildlink2.mk defines several variables that may be used by
packages that use the Open Sound System (OSS) API;
* pthread.buildlink2.mk uses the value of PTHREAD_OPTS and checks for
native pthreads or adds a dependency on devel/pth as needed;
* xaw.buildlink2.mk uses the value of XAW_TYPE to choose a particular
Athena widgets library.
The comments in those buildlink2.mk files provide a more complete
description of how to use them properly.
8.2 Writing buildlink2.mk files
===============================
A simple example of a buildlink2.mk file for a mythical package foo
follows:
BUILDLINK_PACKAGES+= foo
BUILDLINK_PKGBASE.foo= foo
BUILDLINK_DEPENDS.foo?= foo>=1.0
BUILDLINK_PKGSRCDIR.foo?= ../../category/foo
EVAL_PREFIX+= BUILDLINK_PREFIX.foo=foo
BUILDLINK_PREFIX.foo_DEFAULT= ${LOCALBASE}
BUILDLINK_FILES.foo= include/foo.h
BUILDLINK_FILES.foo+= include/bar.h
BUILDLINK_FILES.foo+= lib/libfoo.*
BUILDLINK_TARGETS+= foo-buildlink
foo-buildlink: _BUILDLINK_USE
The first section controls how the dependency on foo is added. The
dependency is constructed from four parts:
(1) BUILDLINK_PACKAGES is the global list of packages for which
dependencies will be added by buildlink2;
(2) BUILDLINK_DEPENDS.foo is the actual dependency recorded in the
installed package;
(3) BUILDLINK_PKGSRCDIR.foo is the location of the foo pkgsrc
directory;
(4) BUILDLINK_DEPMETHOD.foo (not shown above) controls whether we use
BUILD_DEPENDS or DEPENDS to add the foo dependency, where the
full dependency is added if BUILDLINK_DEPMETHOD.foo contains "full".
The second section controls which files are linked into ${BUILDLINK_DIR}:
(1) BUILDLINK_PREFIX.foo is the installation prefix of the package which
we derive by using EVAL_PREFIX;
(2) BUILDLINK_FILES.foo is a list of files (shell globs allowed) relative
to the BUILDLINK_PREFIX.foo directory and will be symlinked into
${BUILDLINK_DIR};
(3) BUILDLINK_FILES_CMD.foo (not shown above) is a shell pipeline that
outputs a list of files relative to the BUILDLINK_PREFIX.foo
directory and will be symlinked into ${BUILDLINK_DIR}.
The remaining parts create the foo-buildlink target that actually performs
the symlinking and adds the foo-buildlink target to BUILDLINK_TARGETS,
which is the global list of targets to execute at do-buildlink time.
9 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.
* Make sure PKG_DEVELOPER=1 is in /etc/mk.conf
* Create a new directory, and run
# url2pkg http://www.example.com/path/to/distfile.tar.gz
You'll need to have pkgsrc/pkgtools/url2pkg installed for that.
* Edit the Makefile as requested.
* Fill in DESCR
* ``make configure''
* Add any dependencies glimpsed from 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 ${WRKDIR}/.newpatches/* patches
# make mps
# make clean
[ mkpatches, patchdiff and pkgvi are from pkgsrc/pkgtools/pkgdiff ]
Doing as non-root user will assure that no files are modified that
shouldn't, esp. not during the build phase.
* Look at Makefile, fix if necessary; see section 4.1.
* Generate a PLIST:
# make install
# make print-PLIST > PLIST
# make deinstall
# make install
# make deinstall
You usually need to be root to do this.
* Look if there are any files left:
# make print-PLIST
If this brings up any files that are missing in PLIST, add them.
* Now that the PLIST is ok, install the package again and make a binary
package:
# make reinstall && make package
* Delete the installed package:
# pkg_delete blub
* Repeat the above find command, which shouldn't find anything now:
# make print-PLIST
* Reinstall the binary package:
# pkg_add ..../blub.tgz
* Play with it. Make sure everything works.
* Run pkglint from pkgsrc/pkgtools/pkglint, and fix the problems it reports.
# pkglint
* Submit (or commit, if you have cvs access); see section 11.
10 FAQs & features of the package system
========================================
10.1 Packages using GNU autoconf
================================
If your package uses GNU autoconf created configure scripts, add the following
to your package's Makefile:
GNU_CONFIGURE= yes
Note that this appends --prefix=${PREFIX} to CONFIGURE_ARGS, so you don't
have to do that yourself, and this may not be what you want.
10.2 Other distrib methods than .tar.gz
=======================================
If your package uses a different distribution method from .tar.gz, take a
look at the package for pkgsrc/editors/sam, which uses a gzipped shell archive
(shar), but the quick solution is to set EXTRACT_SUFX to the name after the
DISTNAME field, and add the following to your package's Makefile:
EXTRACT_SUFX= .msg.gz
EXTRACT_CMD= zcat
10.3 Packages not creating their own subdirectory
=================================================
Your package doesn't create a subdirectory for itself (like GNU software
does, for instance), but extracts itself in the current directory: see
pkgsrc/editors/sam again, but the quick answer is:
WRKSRC= ${WRKDIR}
Please note that the old
NO_WRKSUBDIR= yes
has been deprecated and should not be used.
10.4 Custom configuration process
=================================
Your package uses a weird Configure script: See the top package, but the
quick answer is:
HAS_CONFIGURE= yes
CONFIGURE_SCRIPT= Configure
CONFIGURE_ARGS+= netbsd13
10.5 Packages not building in their DISTNAME directory
======================================================
Your package builds in a different directory from its base DISTNAME - see
tcl and tk packages:
WRKSRC= ${WRKDIR}/${DISTNAME}/unix
10.6 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". But there's no archive of
the distfiles on ftp.netbsd.org and the one on ftp.freebsd.org contains
many distfiles for which there are no ports (yet).
The answer here is to do a "make fetch-list" in /usr/pkgsrc, 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 an 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
% 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 typing:
% make mirror-distfiles
If you even decide to ignore NO_{SRC,BIN}_ON_{FTP,CDROM}, then you can
get all & everything by typing
% make fetch NO_SKIP=yes
10.7 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 look like:
ftp_proxy=ftp://orpheus.amdahl.com:80/
http_proxy=http://orpheus.amdahl.com:80/
10.8 If your patch contains an RCS ID
=====================================
See section 4.3 on how to remove RCS IDs from patch files.
10.9 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
10.10 Is there a mailing list for pkg-related discussion?
=========================================================
Yes. We are using tech-pkg@netbsd.org for discussing package related
issues. To subscribe do:
% echo subscribe tech-pkg | mail majordomo@netbsd.org
10.11 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:
/usr/bin/fetch
${LOCALBASE}/bsd/bin/ftp
/usr/bin/ftp
On a default NetBSD install, 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.
10.12 Dependencies on other packages
====================================
Your package may depend on some other package being present - and there are
various ways of expressing this dependency. NetBSD supports the
BUILD_DEPENDS and DEPENDS definitions, as well as dependencies via
buildlink2.mk (see section 8).
The basic difference between the two definitions is as follows: The
DEPENDS definition registers that pre-requisite in the binary package,
whilst the BUILD_DEPENDS definition does not.
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 recognised by pkg_info(1).
(a) If your package needs to use another package to build itself, this
is specified using the BUILD_DEPENDS definition.
BUILD_DEPENDS+= autoconf-2.13:../../devel/autoconf
(b) If your package needs a library with which to link, this is specified
using the DEPENDS definition. An example of this is the pkgsrc/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-* DEPEND.
(c) If your package needs some executable to be able to run correctly, this
is specified using the DEPENDS definition. The pkgsrc/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 pkgsrc/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
pkgsrc/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
pkgsrc/devel/gettext-m4 package.
10.13 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 pkgsrc/x11/Xaw3d and pkgsrc/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".
10.14 Software which has a WWW Home Page
========================================
The NetBSD packages system now supports a variable called HOMEPAGE.
If the software being packaged has a home page, the Makefile should
include the URL for that page in the HOMEPAGE variable. The definition
of the variable should be placed immediately after the MAINTAINER
variable.
10.15 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 md5 checksum will no longer match. The correct way to work around this
is to update the package's md5 checksum to match the package on the master
site (beware, any mirrors may not be up to date yet!), and to remove the
old distfile from ftp.netbsd.org's /pub/NetBSD/packages/distfiles directory.
Furthermore, a mail to the package's author seems appropriate making sure
the distfile was really updated on purpose, and that no trojan horse or so
crept in.
10.16 What does "Don't know how to make /usr/share/tmac/tmac.andoc" mean?
=========================================================================
When compiling the pkgsrc/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 on your machine
(nroff, ...). It is recommended to do that.
In the case of the pkg_install package, you can get away with setting
NOMAN=YES either in the environment or in /etc/mk.conf.
10.17 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
10.18 "Could not find bsd.own.mk" - what's wrong?
=================================================
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 /:
# tar --unlink -pvxf .../comp.tgz
comp.tgz is part of every NetBSD release, please get the one matching
the release you have installed (determine via "uname -r").
10.19 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!
10.20 Packages using (n)curses
==============================
Some packages need curses functionality that wasn't present in NetBSD's own
curses prior to 1.4Y.
If ../../devel/ncurses/buildlink2.mk is included in a package's Makefile,
then a curses library and headers with ncurses functionality are linked
into ${BUILDLINK_DIR} at pre-configure time. If ncurses is actually
required, then define USE_NCURSES in the package's Makefile:
USE_NCURSES= # redrawwin
The comment should indicate which functions are missing.
10.21 Automated security check
==============================
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
pkgsrc/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/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 audit-packages package is strongly recommended.
The following message is displayed as part of the audit-packages
installation procedure:
======================================================================
You may wish to have the vulnerabilities file downloaded daily so that
it remains current. This may be done by adding an appropriate entry
to the root users crontab(5) entry. For example the entry
# download vulnerabilities file
0 3 * * * ${PREFIX}/sbin/download-vulnerability-list >/dev/null 2>&1
will update the vulnerability list every day at 3AM.
In addition, you may wish to run the package audit from the daily
security script. This may be accomplished by adding the following
lines to /etc/security.local
if [ -x ${PREFIX}/sbin/audit-packages ]; then
${PREFIX}/sbin/audit-packages
fi
======================================================================
Note to package developers: When a vulnerability is found, this should be
noted in localsrc/security/advisories/pkg-vulnerabilities, and after the
commit of that file, it should be copied to
/pub/NetBSD/packages/distfiles/vulnerabilities on ftp.netbsd.org.
10.22 What's the proper way to create an account from a package?
================================================================
There are two make variables used to control the creation of package-specific
groups and users at pre-install time. The first is PKG_GROUPS, which is a
list of group[:groupid] elements, where the groupid is optional. The second
is PKG_USERS, which is a list of elements of the form:
user:group[:[userid][:[description][:[home][:shell]]]]
where only the user and group are required, the rest being optional. A
simple example is:
PKG_GROUPS= foogroup
PKG_USERS= foouser:foogroup
A more complex example is that creates two groups and two users is:
PKG_GROUPS= group1 group2:1005
PKG_USERS= first:group1::First\\ User \
second:group2::Second\\ User:/home/second:${SH}
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.
The package Makefile must also set USE_PKGINSTALL to "YES" prior to the
inclusion of bsd.pkg.mk. This will cause the users and groups to be created
at pre-install time, and the admin will be prompted to remove them at
post-deinstall time. Automatic creation of the users and groups can be
toggled on and off by setting the environment variable PKG_CREATE_USERGROUP
prior to package installation.
10.23 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 doc/HACKS. See doc/HACKS for
examples.
10.24 Packages providing info files
===================================
Some packages install info files or use the makeinfo or install-info
commands. In such cases, the makefile fragment mk/texinfo.mk should be
included in the package Makefile before the inclusion of mk/bsd.pkg.mk.
Newer versions of texinfo (version 4 and above) are, unfortunately,
incompatible from previous versions at the command line level and some
extensions were introduced in the TeXinfo macro set. So the package creator
should ensure that the correct binaries are selected, rather than relying
on the contents of the PATH variable in the shell.
The main info directory file needs to be updated to reflect the
installation of info files. Some packages' installation processes take care
of this for you. Otherwise the NetBSD Packages Collection has an INFO_FILES
definition which can be used to do this. Simply use the
INFO_FILES= ident.info
definition in the package Makefile, where "ident.info" is the name of the
info file which installs an info dir entry.
A package creator should also take care that the package build and install
process uses the correct version of the makeinfo and install-info commands.
Some Makefiles and configure scripts from recent software packages include
the pathnames to the makeinfo and install-info commands. Unfortunately,
older software packages tend not to do this, and, should this be the case,
further action is required of the package creator.
The mk/texinfo.mk makefile fragment will ensure that the proper makeinfo
and install-info commands are available on the system as well as help the
configure and build process of the package to use known binaries for these
commands.
If a minimum version of makeinfo and install-info commands are required,
define TEXINFO_REQD in the package's Makefile to this minimum version.
If a package is not well behaved (i.e., it does not pick MAKEINFO or
INSTALL_INFO in the environment at configure or build time) you should do
one of the following, whichever is more appropriate:
a) patch the package files so MAKEINFO or INSTALL_INFO are picked from the
environment at configure or build time and get used instead of
relying on makeinfo or install-info being accessible in PATH;
b) put TEXINFO_OVERRIDE=YES in the package Makefile to let some sed
manipulation happen on some packages source files (see contents of
mk/texinfo.mk).
10.25 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/vmare-module, fonts/acroread-jpnfont, sysutils/storage-manager,
www/ap-aolserver, www/openacs. Try to be consistent with them.
10.26 Using pkgsrc on non-NetBSD (Darwin, FreeBSD, IRIX, Linux, OpenBSD, Solaris)
=================================================================================
In order to use pkgsrc on a non-NetBSD operating system, you must first
bootstrap the necessary utilities (BSD make, pkg_*, ...). See
http://www.netbsd.org/Documentation/software/packages.html#bootstrap
for information on boostrapping. Binary bootstrap-kits are available from that
URL as well. If your Operating System is not yet supported, we encourage you to
port the bootstrap-kit and submit your changes.
10.27 Configuration files handling and placement
================================================
The global variable PKG_SYSCONFBASE (and some others) can be set by the
system administrator in /etc/mk.conf to define the place where
configuration files get installed. Therefore, packages must be adapted to
support this feature. Keep in mind that you should only install files that
are strictly necessary in the configuration directory, files that can
go to $PREFIX/share should go there.
We will take a look at available variables first (bsd.pkg.mk contains more
information). PKG_SYSCONFDIR is where the configuration files for a package
may be found (that is, the full path, e.g. /etc or /usr/pkg/etc). This
value may be customized in various ways:
1) PKG_SYSCONFBASE is the main config directory under which all package
configuration files are to be found. Users will typically want to set
it to /etc, or accept the default location of $PREFIX/etc.
2) PKG_SYSCONFSUBDIR is the subdirectory of PKG_SYSCONFBASE under which
the configuration files for a particular package may be found. Defaults
to $SYSCONFBASE
3) PKG_SYSCONFVAR is the special suffix used to distinguish any overriding
values for a particular package (see next item). It defaults to
${PKGBASE}, but for a collection of related packages that should all
have the same PKG_SYSCONFDIR value, it can be set in each of the
package Makefiles to a common value.
4) PKG_SYSCONFDIR.${PKG_SYSCONFVAR} overrides the value of
${PKG_SYSCONFDIR} for packages with the same value for PKG_SYSCONFVAR.
As an example, all the various KDE packages may want to set
PKG_SYSCONFVAR to "kde" so admins can set ${PKG_SYSCONFDIR.kde} in
/etc/mk.conf to define where to install KDE config files.
Programs' configuration directory should be defined during the configure
stage. Packages that use GNU autoconf can usually do this by using the
--sysconfdir parameter, but this brings some problems as we will see now.
When you change this pathname in packages, you should not allow them to
install files in that directory directly. Instead they need to install
those files under share/examples/${PKGNAME} so PLIST can register them.
Once you have the required configuration files in place (under the
share/examples directory) the variable CONF_FILES should be set to copy
them into PKG_SYSCONFDIR. The contents of this variable is formed by pairs
of filenames; the first element of the pair specifies the file inside the
examples directory (registered by PLIST) and the second element specifies
the target file. This is done this way to allow binary packages to place
files in the right directory using INSTALL/DEINSTALL scripts which are
created automatically. The package Makefile must also set USE_PKGINSTALL
to "YES" prior to the inclusion of bsd.pkg.mk to use these automatically
generated scripts. The automatic copying of config files can be toggled by
setting the environment variable PKG_CONFIG prior to package installation.
Here is an example, taken from mail/mutt/Makefile:
EGDIR= ${PREFIX}/share/doc/mutt/samples
CONF_FILES= ${EGDIR}/Muttrc ${PKG_SYSCONFDIR}/Muttrc
As you can see, this package installs configuration files inside EGDIR,
which are registered by PLIST. After that, the variable CONF_FILES lists
the installed file first and then the target file. Users will also get an
automatic message when files are installed using this method.
10.28 Packages providing login shells
=====================================
If the purpose of the package is to provide a login shell, the variable
PKG_SHELL should contain the full pathname of the shell executable installed
by this package. The package Makefile also must set USE_PKGINSTALL to "YES"
prior to the inclusion of bsd.pkg.mk to use the automatically generated
INSTALL/DEINSTALL scripts.
An example taken from shells/zsh:
USE_PKGINSTALL= YES
PKG_SHELL= ${PREFIX}/bin/zsh
The shell is registered into /etc/shells file automatically in the
post-install step by the auto-generated INSTALL script and removed in the
deinstall step by the DEINSTALL script.
10.29 Packages providing locale catalogues
==========================================
If the package provides its own locale catalogues, the variable
USE_PKGLOCALEDIR should be defined. It will ensure that the package's
Makefile template files are fixed and point to the correct locale directories
(which may vary, depending on OS), if necessary. See also section 5.1 for
details about ${PKGLOCALEDIR}. This functionality is buildlink2-only.
10.30 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
pkgsrc/security/sudo) and then put the following into your /etc/mk.conf:
SU_CMD=/usr/pkg/bin/sudo /bin/sh -c
10.31 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.
10.32 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.
11 Submitting & Committing
==========================
11.1 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 NetBSD developers to
guarantee that the packages don't contain any trojan horses etc.
This is not to piss anyone off 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.
* packages:
First, check that your package is complete, compiles and runs well; see
section 9 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(1) 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.
11.2 Committing: Importing the package into CVS
===============================================
This section is only of interest for NetBSD developers with write
access to the NetBSD pkgsrc repository. Please remember that cvs
imports files relative to the cwd, 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
and 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.
For new packages, "cvs import" is preferred to "cvs add" because
the former gets everything with a single command, and provides a
consistent tag.
11.3 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 recognise 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.
11.4 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.
12 A simple example of a package: bison
=======================================
I 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 me, but
it's useful for the purposes of this exercise.
12.1 files
==========
The file contents in this section must be used without the "> " prefix.
12.1.1 Makefile
===============
# <$>NetBSD<$>
DISTNAME= bison-1.25
CATEGORIES= devel
MASTER_SITES= ${MASTER_SITE_GNU}
MAINTAINER= thorpej@netbsd.org
HOMEPAGE= http://www.gnu.org/software/bison/bison.html
COMMENT= GNU yacc clone
GNU_CONFIGURE= yes
INFO_FILES= bison.info
.include "../../mk/texinfo.mk"
.include "../../mk/bsd.pkg.mk"
12.1.2 DESCR
================
GNU version of yacc. Can make re-entrant parsers, and numerous other
improvements. Why you would want this when Berkeley yacc(1) is part
of the NetBSD source tree is beyond me.
12.1.3 PLIST
================
@comment <$>NetBSD<$>
bin/bison
man/man1/bison.1.gz
@unexec install-info --delete %D/info/bison.info %D/info/dir
info/bison.info
info/bison.info-1
info/bison.info-2
info/bison.info-3
info/bison.info-4
info/bison.info-5
@exec install-info %D/info/bison.info %D/info/dir
share/bison.simple
share/bison.hairy
12.1.4 Checking a package "pkglint"
===================================
The NetBSD package system comes with a tool called "pkglint" (located in the
directory "pkgsrc/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
OK: checking ./DESCR.
OK: checking Makefile.
OK: checking distinfo.
OK: checking patches/patch-aa.
looks fine.
Depending on the supplied command line arguments (see "man pkglint") more
verbose checks will be performed. Use e.g. "pkglint -v" for a very verbose
check.
12.2 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 pkg
Create Makefile, DESCR and PLIST as in section 11.1,
then continue with fetching the distfile:
# make fetch

To create:
- cd /usr/pkgsrc ; make install ; make package
- upload /usr/pkgsrc/packages to
ftp://ftp.netbsd.org/pub/NetBSD/packages/\
`uname -r | sed 's@\.\([0-9]*\)[\._].*@\.\1@'`/`uname -p`
- if necessary ln -s `uname -m` `uname -p`
Disk space needed: unknown.
Packages for a release version of NetBSD should be uploaded to the
directory major.minor corresponding to the appropriate release. Packages
for NetBSD with versions such as "1.5.1" should be uploaded to the "1.5"
directory, stripping the tiny number off the directory name. For packages
that need to be tightly coupled with the OS Version, such as LKM's, you
may create a major.minor.tiny release directory, and place those packages
therein. Such packages should be marked with the variable
"OSVERSION_SPECIFIC=yes" to mark them in some way for binary package
builders.
