Mac OS X Snow Leopard 32/64 (i386/x86_64) ABI issue:
Mac OS X Snow Leopard (10.6) supports 64-bit binaries on most Intel
Macs and builds those by default on such machine. This causes
problems with a lot of packages which get confused because
"MACHINE_ARCH" is set to "i386" (on a 64-bit system!). There are also
packages that don't support 64-bit under Mac OS X at all. Because of
this, the default for pkgsrc is use use the 32-bit ABI, which results
in packages being compiled and run in i386 mode. For a longer
discussion, see:
http://mail-index.NetBSD.org/pkgsrc-users/2009/09/24/msg010817.html
Developer tools:
If you haven't already, you will need to install the Mac OS X Developer
Tools package. Depending on the version of OS X you are running, you
may have this on CD. If not, you can download it from Apple's
Developer Connection. (You will need to register for a free ADC
account.) See http://developer.apple.com/macosx/ for details.
(If you don't want or need the full Xcode GUI, download and install
Command Line Tools for Xcode.)
Then start Xcode, go to "Preferences" - "Downloads" and install
the "Command Line Tools".
If you plan to build packages that use the X11 Window System, you
will also need to make sure you have an Xserver installed. Download
XQuartz from http://xquartz.macosforge.org/landing/
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:
10.8: current, PRs may 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: 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]
