[Pythonmac-SIG] Debugging Extensions on Mac
Hello all, Sorry if this isn't the right forum for this, but I have been searching Google for a couple days without finding any close answers. I am trying to debug Python extensions on the Mac. I am already able to compile/link both debug and release versions of my extension using both Xcode and distutils. The extension fully works in Release mode. I copied down the source for Python-2.4.3 and made a debug version of the Python interpreter. The problem comes when I try to import the debug version of my extension in the debug Python interpreter. I get the following: Traceback (most recent call last): File "", line 1, in ? ImportError: Failure linking new module: extension.so: Symbol not found: _Py_InitModule4 Referenced from: extension.so Expected in: dynamic lookup I'm trying to avoid debugging using printfs because this can get tedious when working with complex code. This particular extension above doesn't really do much of importance except read/write a file, but I made it for testing purposes. Anyone have any experience stepping through Python extension code on Mac and have seen this?

Unfortunately I am still getting the same error. Thanks for the response, Gustavo ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig

Ignore my previous message. This /did/ work. I was pointing my include paths to the wrong location. Thanks for the help!
