I want to build my python extension for Python 2.3, 2.4 and 2.5 on the same Mac. Build Python 2.3 and Python 2.4 has been working well for a long time. But after I installed Python 2.5 it seems that I can no longer link a against Python 2.4 without changing sym link /Library/Frameworks/Python.framework/ Versions/Current to point at the one I want to build against. The problem did not arise with Python 2.3 and Python 2.4 because Python 2.3 is in /System/Library and Python 2.4 is in /LIbrary. Telling ld which framework folder to look in allows both to be linked against. Is there a way to force ld to use a particular version of the python framework or do I have to change the symlink each time I build against a different version? This type of problem does not happen on Windows or Unix by design. Use an absolute path to the library rather than -framework.

That is, add '/Library/Frameworks/Python.framework/Versions/2.4/ Python' to the link command instead of '-framework Python'.

Or use distutils!

That's definitely advisable anyway, that way you'll automaticly get
the right flags to compile and link the extension :-)
