如何用boost.python编写python扩展

#include "stdafx.h"

#include <boost/python.hpp>

#define EXPORT_SYMBOL_TO_PYTHON(x) boost::python::def(#x, x)

void Recognise(PyObject* pObj)
{
   MessageBoxA(NULL, ((PyStringObject*)pObj)->ob_sval, "message", MB_OK );
}

BOOST_PYTHON_MODULE(DllForPython)
{
    EXPORT_SYMBOL_TO_PYTHON(Recognise);
}

Python脚本调用部分(将DLL扩展目录加入到sys.path):

# -*- coding: gbk -*-

import sys
sys.path.append('./Debug')
import DllForPython
DllForPython.Recognise("Everything is OK")
