I work under Linux.

1. I wrote a file a.cpp (where there is a function f for which I make an extern "c" {} declaration at the top of the file).
2. I compiled g++ -shared -fPIC -o a.so a.cpp.
3. I wrote a.py where I have ctypes.cdll.LoadLibrary('./a.so'). If I actually run this file then everything is fine and I can call the function f.
4. I wrote b.py which has import a. Here I get an error at that import line: dynamic module does not define module export function (PyInit_a).

I guess I need to somehow modify the import with some __init__ or something, but maybe something else. Does somebody know what to do?

Thanks!
