We do things like this in numpy. We've extended distutils to allow functions in
the sources list for Extension.
from numpy.distutils.core import Extension
from distutils.dep_util import newer
def generate_source_c(ext, build_dir):
target = os.path.join(build_dir, 'source.c')
if newer(__file__, target):
# ... parse Python headers
contents = """
#include "Python.h"
/* ... */
""" % (stuff, more_stuff)
f = open(target, 'w')
f.write(contents)
f.close()
return target
ext = Extension('my_extension',
sources=[generate_source_c],
)
setup(#...
ext_modules=[ext]
)
