Mac OS X Snow Leopard Binary ABI problem:

Mac OS X Snow Leopard 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. It is therefore
recommended that use the "--abi 32" option of "bootstrap"
under Mac OS X Snow Leopard at the moment.


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.

Note for MacOS X 1.4 (Tiger) you will need to download xcode 2.5
if you intend to use gcc 4.  gcc 4.0.0 bundled with xcode 2.0 on
the desktop installation dvds builds broken pkg_install tools.

If you plan to build packages that use the X11 Window System, you will
also need to make sure you have X11 installed. OS X 10.3 (Panther)
includes X11 and X11 SDK packages on CD. If you are using an older
version of OS X, you can install the XFree86 packages instead, from
www.xfree86.org.

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
