Basically: 10.9's sed is broken, bootstrap works around this via nbsed on 10.9, and therefore while a 10.6 boostrap's binaries will *run* on 10.9, one can't reliably build new packages. (Thanks to jperkin@ for pointing this out.)

* system tools issues
|
|
|
|
** gcc vs clang
|
|
|
|
Older versions of Mac OS X (with XCode, of course) provided gcc, and
|
|
pkgsrc defaulted to using gcc. With 10.9, gcc is no longer present
|
|
and one must bootstrap with "--compiler=clang". (Arguably, pkgsrc
|
|
should default to clang on 10.9.)
|
|
|
|
** i386 vs x86_64 ABI issue
|
|
|
|
Mac OS X Snow Leopard (10.6) through Mavericks (10.9) supports 64-bit
|
|
binaries on most Intel Macs and build those by default on such
|
|
machine. This has caused problems with packages which get confused
|
|
because "MACHINE_ARCH" is in some OS versions set to "i386" (on a
|
|
64-bit system!).
|
|
version: uname -m : uname -p
|
|
10.6: i386 : i386
|
|
10.9: x86_64 : i386
|
|
|
|
There are of course some packages which will fail in i386 mode, and
|
|
some in x86_64 mode. Because of all this, the default for pkgsrc was
|
|
set to use the 32-bit ABI, which results in packages being compiled
|
|
and run in i386 mode. In addition, there are some Intel Macs (older
|
|
Mac Minis) which can only run i386 and not x86_64. For a longer
|
|
discussion, see:
|
|
http://mail-index.NetBSD.org/pkgsrc-users/2009/09/24/msg010817.html
|
|
|
|
As of 2014, the decision to default to i386 should probably be
|
|
revisited.
|
|
|
|
** sed in 10.9
|
|
|
|
The sed that comes with 10.9 appears to be broken; it exits when
|
|
called on files with UTF-8 or other apparently-binary content.
|
|
Therefore, pkgsrc uses nbsed on 10.9.
|
|
|
|
* Developer tools and prerequisites
|
|
|
|
** basic tools
|
|
|
|
If you haven't already, you will need to install the Mac OS X
|
|
Developer Tools package (XCode) to obtain a compiler, etc. The
|
|
procedure depends on the version of Mac OS X; recent versions use the
|
|
App Store.
|
|
|
|
Note that as of 10.9, cvs is no longer provided. You can build
|
|
devel/scmcvs. To obtain pkgsrc in order to bootstrap and build cvs,
|
|
it may be useful to use git to clone https://github.com/jsonn/pkgsrc
|
|
|
|
** X11
|
|
|
|
X11 used to be built into Mac OS X, but as of 10.8 it is not.
|
|
Install XQuartz from http://xquartz.macosforge.org/landing/
|
|
|
|
** XL compiler
|
|
|
|
[The text in this section dates from 2004-10-07! Please update it if
|
|
you have used XL since then.]
|
|
|
|
Experimental support for IBM's XL C/C++ compiler is present (tested
|
|
with version 6.0). To use it, set:
|
|
|
|
PKGSRC_COMPILER=xlc
|
|
|
|
in mk.conf. XL C uses the Apple provided libtool to create shared
|
|
libraries, however, we must force it to call libtool with the full
|
|
path to avoid calling the pkgsrc provided GNU libtool with arguments
|
|
that it does not understand.
|
|
|
|
edit the template configuration file /opt/ibmcmp/vac/6.0/etc/vac.base.cfg
|
|
and set:
|
|
|
|
libtool = /usr/bin/libtool
|
|
|
|
then run:
|
|
|
|
/opt/ibmcmp/vacpp/6.0/bin/vacpp_configure -gcc /usr -install -force
|
|
|
|
as root to install the configuration.
|
|
|
|
to bootstrap with xlc, you need to make sure CFLAGS contains "-ma":
|
|
|
|
env CC=/opt/ibmcmp/vacpp/6.0/bin/xlc CFLAGS=-ma ./bootstrap
|
|
|
|
* Mac OS X Versions
|
|
|
|
pkgsrc is a volunteer project, and individuals support/fix packages
|
|
and platforms as they choose. However, pkgsrc contributors as a group
|
|
share both a bugtracker and norms about what is ok to break and what
|
|
is not. To describe these norms, we define levels of concern, keeping
|
|
in mind that there are no guarantees:
|
|
|
|
SUPPORTED doesn't mean that anyone is required to fix your problem; it
|
|
means that we agree that it is broadly desireable that such problems
|
|
be fixed and that we therefore allow them to be listed in our issue
|
|
tracker.
|
|
|
|
DEPRECATED means that individual problems are not of interest, but
|
|
pkgsrc overall working is of enough interest to be allowed to be
|
|
listed in the issue tracker.
|
|
|
|
IGNORED means we are not willing to expend issue tracker resources
|
|
(clutter for those reviewing the db) at all.
|
|
|
|
Given the above definitions, the pkgsrc developers label versions of
|
|
Mac OS X as follows:
|
|
|
|
10.9 (13.1.0): current, PRs may be filed. Structurally breaking
|
|
pkgsrc on 10.9 is considered not ok. [SUPPORTED]
|
|
|
|
10.8: somewhat old, PRs may still be filed. Structurally breaking
|
|
pkgsrc on 10.8 is considered not ok. [SUPPORTED]
|
|
|
|
10.7: old, but PRs may still be filed. Structurally breaking pkgsrc
|
|
on 10.7 is considered not ok. [SUPPORTED]
|
|
|
|
10.6 (10.8.0): very old, and individual pkg PRs may be bounced to
|
|
authors to retest with newer versions, and closed if that
|
|
doesn't happen in 14 days. We will for now consider
|
|
structurally breaking pkgsrc on 10.6 to be undesirable. If
|
|
keeping support for 10.6 causes excessive work for maintainers
|
|
it may be moved to IGNORED state any time, without
|
|
warning. [DEPRECATED]
|
|
|
|
10.5 and below: ancient, and PRs will be summarily closed. It is
|
|
acceptable to give zero consideration to causing structural
|
|
problems on 10.5 and below. [IGNORED]
|
|
|
|
Because Apple provides 10.9 as a no-cost upgrade (from 10.6 or higher,
|
|
it is fairly likely that 10.6-10.8 will become DEPRECATED faster than
|
|
they might have otherwise. (The rationale for supporting versions
|
|
beyond the current and previous ones has been the difficulty for users
|
|
to upgrade.)
|
|
|
|
* Bulk build suggestions and issues
|
|
|
|
Clearly, it is desirable for a bulk build to be useful on as many
|
|
computers as possible. The main issues are which ABI and which OS X
|
|
version.
|
|
|
|
** 10.6, --abi=32
|
|
|
|
jperkin@netbsd.org provides a bulk build for quarterly branches
|
|
(--abi=32, OSX 10.6, and therefore gcc 4.2.1, XQuartz,
|
|
X11_TYPE=native):
|
|
http://www.perkin.org.uk/pages/pkgsrc-binary-packages-for-osx.html
|
|
http://mail-index.netbsd.org/pkgsrc-bulk/2014/01/10/msg010276.html
|
|
which should run on any version from 10.6 to 10.9.
|
|
|
|
Note that sed on 10.9 is broken, but a bootstrap on 10.6 will not
|
|
avoid it, so while one can install this bootstrap on 10.9 and run
|
|
binary packages, building packages will not in general work.
|
|
|
|
** 10.9, --abi=64 --compiler=clang
|
|
|
|
Given the 10.9 license situation, a bulk build on 10.9 (and therefore
|
|
clang) seems reasonable, with either --abi=32 or --abi=64. Such
|
|
builds are almost certainly only usable on 10.9, but that is or will
|
|
be soon a large fraction of Macs.
