boost python如何配置，python调用 C/C++

boost python如何配置??? 通过boost python 配置 C/C++（函数，类,类成员变量，类成员函数）的导出,
即 C/C++ 如何配置，python才能调用 C/C++

你的boost.python大概没有编译好。按下面的步骤（改一下相应的目录）.注意目前大多数文档／接口还是用python2.x,比如google API, 你可以考虑编译boost+python2.6
build bjam
D:\opensource\boost_1_43_0\bootstrap.bat

build boost.python
add the following to D:\opensource\boost_1_43_0\tools\build\v2\user-config.jam

看它的文档
http://www.boost.org/doc/libs/1_43_0/libs/python/doc/tutorial/doc/html/python/exposing.html
struct World
{
void set(std::string msg) { this->msg = msg; }
std::string greet() { return msg; }
std::string msg;
};
#include <boost/python.hpp>
using namespace boost::python;

BOOST_PYTHON_MODULE(hello)
{
class_<World>("World")
.def("greet", &World::greet)
.def("set", &World::set)
;
}
。。。

boost python有什么需要配置吗？只要先加Python参数编译一下boost，然后在C++里面用就可以了。

不过Python调用C我推荐直接用标准库中的ctypes，调用C++推荐用SWIG

[a17587060]

#include "boost/python.hpp"
#include "Python.h"

using namespace boost::python;

struct World
{
void set(std::string msg) { this->msg = msg; }
std::string greet() { return msg; }
std::string msg;
};

BOOST_PYTHON_MODULE(hello)
{
class_<World>("World")
.def("greet", &World::greet)
.def("set", &World::set)
;
}



output输出：
