Python.h header file missing on Mac OS X 10.6
Python is a framework on Mac OS X so you need to,
#include <Python/Python.h>You also need to call gcc with the -framework argument to actually do anything inside C,
gcc -shared -o sample.so sample.c -framework Python
I'm not sure about 10.6.8, but Python.h should be in
/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7if you installed the official python.org binary. Try adding
-I/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7to your gcc command and see if that works.
In case you have installed Python using Brew, it may be worthwhile to check the location of where your headers are. Try I/usr/local/Cellar/python/...
