Import C++ function into Python program

Question

I\'m experimenting with python functions right now. I\'ve found a way to import python functions into c/c++ code, but not the other way around.

I have a c++ program

Answer 1

You need to create a python module with that function in it. There are three main ways:

1. Using Swig - this reads your c code and creates a python module from it.
2. Hand coded using the python c api.
3. Using Boost::Python (often the easiest way).

This pdf covers 1 and 2. This page will tell you how to use Boost::Python.

You cannot (easily) use a function that is in a c/c++ program - it must be in a static library (which you can also link your c/c++ program against).

EDIT - Cython Is also worth a mention.
