Segmentation Fault upon importing compiled Cython module

[aromanielloNTIA]

Despite fixing the compile errors I mentioned before, I am still not having success using the Cython API (previous issue: #18)

Since I successfully compiled a .so module, I tried to run the cython_example.py script. This results in a simple but completely uninformative error message:

Segmentation fault (core dumped)

It seems that this error occurs while importing the module (and not when making calls to it after a successful import). As of now, I have no idea what is causing this error or how to fix it. Any input on that would be appreciated.

Thanks

Edit: For more information, I am trying to use the Cython API on Linux (Ubuntu)

I managed to get the Cython version to compile and run, it looks like the following was missing:

setup.py:

from distutils.core import setup
from distutils.extension import Extension
from Cython.Build import cythonize
import numpy as np

setup(
    ext_modules=cythonize(
                [Extension('rsa_api',
                ['rsa_api.pyx'],
                libraries=['RSA_API', 'cyusb_shared'],
                include_dirs=['/usr/local/include', np.get_include()],
                library_dirs=['/usr/local/lib'])])

(note both libraries which were in the RSA_API are now included, and the dirs were updated to where I placed them)

Some of the example scripts still fail with assertions, but it at least imports!
