Request for 64-bit python variants on architectures that support it

[mf2k (Frank Schima)]

Python 2.5 is 32-bit only. Ideally it should build 64-bit on 64-bit PPC and Intel architectures. I suspect the same issue is true for all of the python versions (2.4, 2.5, 2.6 and 3.0).

This is basically true for all software build by MacPorts. Xcode defaults to i386 and ppc, if you did not request x86_64 or ppc64.

Will other ports linking against python work if they are built 32-Bit? Will py25-* modules automatically build 64-Bit, too?

Replying to raimue@macports.org:

I'm pretty sure they won't. You're right that this is really a base issue. OTOH it would be nice to get Python building 4-way universal. Last time I tried with universal_archs="i386 x86_64" it failed.

Ccing maintainer of python26.

I should say that variants should be created for the python ports that build 64-bit. Then we can perhaps create 64-bit variants for the python modules like numpy, scipy, etc.

Partial fix for python26 is available as of r45081.

[MarcusCalhoun-Lopez (Marcus Calhoun-Lopez)]

Partial fix for python30 is available as of r46197.

[MarcusCalhoun-Lopez (Marcus Calhoun-Lopez)]

64-bit python support is now in python26 and python30.
A brief inspection of python25 indicates that the same changes would be more difficult to apply.
Can this ticked therefore be closed?

[mf2k (Frank Schima)]

I currently use python 2.5 in production and will for the foreseeable future. If you can do this for python25 it would be greatly appreciated. It's going to take a long time before most code switches over to 2.6+.

Patch to support the universal_archs setting from macports.conf

Diff against Portfile from SVN HEAD to support universal_archs

[jewart@…]

Added two patch files for Python 2.5 to support the universal_archs setting in macports.conf. I had a bit of a row with this because the python port doesn't use autoconf, so I had to fix configure.in / Makefile.pre.in, and run autoconf, then diff the pre-existing configure script against the output from autoconf, as well as add support for the setting in the Makefile.pre.in. I'll try to add these changes to python26 and python30 when I have time.

To make this work, you need to build macports from source using the x86_64 architecture and then add "universal_archs x86_64" to your macports.conf and add +universal to your variants.conf to make sure all your builds pick up the x86_64 settings.

I apologize, I missed the bit above about python26 and python30 having these changes, ignore the bit about me fixing them.

In light of Snow Leopard and the python ports working fine with it, I think this ticket can be closed now.
