How to pass flag to gcc in Python setup.py script?

I'm writing a Python extension in C that requires the CoreFoundation framework (among other things). This compiles fine with:

gcc -o foo foo.c -framework CoreFoundation -framework Python

("-framework" is an Apple-only gcc extension, but that's okay because I'm using their specific framework anyway)

How do I tell setup.py to pass this flag to gcc?

I tried this, but it doesn't seem to work (it compiles, but then complains of undefined symbols when I try to run it):

from distutils.core import setup, Extension
setup(name='foo',
      version='1.0',
      autho开发者_高级运维r='Me',
      ext_modules=[Extension('foo',
                             ['foo.c'],
                             extra_compile_args=['-framework CoreFoundation'])])

Edit:

This appears to work:

from distutils.core import setup, Extension
setup(name='foo',
      version='1.0',
      author='Me',
      ext_modules=[Extension('foo',
                             ['foo.c'],
                             extra_link_args=['-framework', 'CoreFoundation'])])

Maybe you need to set extra_link_args, too? extra_compile_args is used when compiling the source code, extra_link_args when linking the result.
