Building a python module and linking it against a MacOSX framework

Question

I\'m trying to build a Python extension on MacOSX 10.6 and to link it against several frameworks (i386 only). I made a setup.py file, using distutils and the Extension object.

Answer 1

Although long after the dust has settled, having the same question myself I dug around a little bit and found this:

/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/distutils/sysconfig.py

   if 'ARCHFLAGS' in os.environ:
                archflags = os.environ['ARCHFLAGS']
            else:
                archflags = '-arch i386 -arch ppc -arch x86_64'
            _config_vars['ARCHFLAGS'] = archflags
            if archflags.strip() != '':
                _config_vars['CFLAGS'] = _config_vars['CFLAGS'] + ' ' + archflags
                _config_vars['LDFLAGS'] = _config_vars['LDFLAGS'] + ' ' + archflags

I'm coming at the problem from a different angle - on 10.6 distutils is trying to build C extensions and as complains because there's no PPC portion in the 10.6 SDK.

However,

 export ARCHFLAGS="-arch i386 -arch x86_64"
 python setup.py build

Worked like a charm.
