The best way to call C++ function from shared object in python

Question

What's the best way to call C++ function from shared object in python. Can I can solve this problem without additional python extension?

Answer 1

Perhaps you could investigate ctypes , although you will need to know things like the mangled name of the function and the correct calling convention.

If that doesn't work you'll need to create a C wrapper around the C++ code.

Answer 2

If you have the C++ source code, I would say boost python is the best way because it's very easy to get this up and running and it's flexible. If you don't have C++ source then checkout ctypes.

Answer 3

另一种方法是使用swig（http://www.swig.org/）生成一个包装C ++代码的python模块。
