Thanks for any clues. > Well, it's looking for test1ctypes.dylib, which I guess is a MacOSX shared library? Meanwhile, you made a test1ctypes.so, which is why it can't find it. You could try using this instead:
_test1 = N.ctypeslib.load_library('test1ctypes.so', '.') or try to get gcc to make a test1ctypes.dylib.
