Compiling Python 2.4 on A 32-Bit Mac with Snow Leopard

Python 2.4 on a 32-bit Mac using Snow Leopard without a buildout.

Florian Schulze has created a buildout that compiles Python 2.4, 2.5, and 2.6 on Snow Leopard. By habit, I generally compile my Python interpreters "by hand" so I have a clue what's going on. I really just looked at Florian's buildout to see what it did and did that by hand.

Here's what I had to do to get Python 2.4 compiled on a fresh Snow Leopard install (not an upgrade) on a 32-bit Mac Book Pro (a Core Duo, not a Core 2 Duo; those have other issues).:

  • Install Fink
  • Install the readline5-dev library using "fink install" (for readline support in Python). If you don't compile against a "real" readline, Python will probably compile but it will probably buserror in an interactive shell or you'll not have any readline support in the interactive shell.
  • Download Python 2.4.6
  • Apply Florian's patch to the unpacked source of the Python 2.4.6 tarball. Note that things mostly sorta work without this patch, but (in particular) supervisor won't run without this patch (can't import the "resource" module and other POSIX-related things).
  • Use the following command to configure Python 2.4: 
        CC="gcc -I/sw/include -L/sw/lib" ./configure MACOSX_DEPLOYMENT_TARGET=10.6 --disable-tk --prefix=$HOME/opt/Python-2.4.6
  • Use the following command to install Python 2.4: 
        CC="gcc -I/sw/include -L/sw/lib" MACOSX_DEPLOYMENT_TARGET=10.6 make install

Problematic patch file

That patch file does not work for me against a newly downloaded Python 2.4.6 tarball:

Hmph

On a 64-bit (with 32-bit EFI)

I managed to get Python 2.4 compiled using this configuration:

CC="gcc-4.2 -march=x86-64 -isystem /opt/local/include -L/opt/local/lib -L/opt/local/lib"

See http://trac.macports.org/ticket/20933 (grep for "under-specify").
