Calling c++ function, from Python script, that uses OpenCV libraries

I've a c++ code on my mac that uses non-standard lybraries (in my case,
OpenCV libs) and need to compile this so it can be called from other
computers (at least from other mac computers). Runned from python. So I've
3 fundamental questions:
How to compile my project so it can be used from python? I've read that I
should create a *.so file but how to do so?
Should it work like a lib, so python calls some specific functions, chosen
in python level?
Or should it contain a main function that is executed from command line?
Any ideas on how to do so? PS: I'm using the eclipse IDE to compile my c++
project.
Cheers,
