[Python-Dev] fat binaries for OSX

Mon Apr 17 21:51:56 CEST 2006

Hi,
I've uploaded 3 patches that form the core of the python24-fat tree 
that Bob Ippolito and I have been maintaining for a while. With these 
patches one can build fat/universal binaries for python that run 
natively on OSX 10.3 and later.
I'd like to merge these patches to the trunk, but would like some 
review. I'm especially unhappy with the code duplication in patch 
1471925, but don't know how to solve that.
* Patch 1471883: --enable-universalsdk on Mac OS X
 This patch introduces a --enable-universalsdk flag for configure
 and the required changes to the build system to get this to work.
 When this flag is used Python is build as a universal (aka fat)
 binary.
* Patch 1471761: test for broken poll at runtime
 This patch moves the HAVE_BROKEN_POLL test from configure-time
 to runtime. With this patch we can have a single binary on OSX
 that works on OSX 10.3.9 or later while having select.poll
 available on those versions of the OS that have a functioning
 version poll().
* Patch 1471925: Weak linking support for OSX
 This patch adds weak linking support to the posix, time and
 socket modules. That is, the existance of a number of functions
 is tested for at runtime (on OSX only).
 With this patch one can use a python binary that was build on
 OSX 10.4 on OSX 10.3 systems, without loosing access to APIs
 that were introduced in 10.4 on OSX 10.4 systems.
