Replace python config files for C++ extension

Question

I'm trying to write a simple module in C++ and import it into Python. However, when I try to import the module using import greet, I get a ImportError: dynamic module does not define module export function (PyInit_greet) error.

After reading another SO question related to this problem (here) I thought that I may be having version problems (since I'm using Python3.5). But then again, every command I'm using to build and install, I'm using with Python3.5, so how could I be having version problems? (python3.5 build setup.py and python3.5 setup.py install).

I'm trying to create a modified version of the simple project described in the Python Docs (here), and everything works fine until I try to import the module.

Here is my setup.py file:

from distutils.core import setup, Extension

greet_module = Extension('greet',
        define_macros=[('MAJOR_VERSION','1'),
                   ('MINOR_VERSION','0')],
        include_dirs=['/usr/local/include'],
        # clang: warning: libstdc++ is deprecated; move to
        # libc++ with a minimum deployment target of OS X 10.9
        sources=['greet.cpp'])

setup (name='Greet_Package',
       version='1.0',
       description='This is a demo package',
       author='ralston',
       author_email='null',
       url='https://google.com',
       long_description='''This is really just a demo package''',
       ext_modules=[greet_module])

Could it be related to my include_dirs parameter? My Python3.5 isn't actually installed there, but I tried putting my Python3.5 path in include_dirs but I got the same error. When I build setup.py here's my output:

Any help would be greatly appreciated.
