如何用boost.python编写python扩展

Dll扩展部分（文件名与模块名一致，将生成的DLL扩展名改为.pyd)：

#include "stdafx.h"



#include <boost/python.hpp>



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



void MsgBox(PyObject* pObj)

{

   MessageBoxA(NULL, ((PyStringObject*)pObj)->ob_sval, "message", MB_OK );

}



BOOST_PYTHON_MODULE(DllForPython)

{

    EXPORT_SYMBOL_TO_PYTHON(MsgBox);

}

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.MsgBox("Everything is OK")
