按如下文章中的例子，VC++封装成python可用的dll，编译时出错，请问是为什么？（我封装非类非结构体的普通函数，编译成功，python也可调用成功）
http://www.cppblog.com/jinq0123/archive/2008/05/29/buildinghybridsystemswithboostpython_c.html
#define BOOST_PYTHON_SOURCE
#include "stdafx.h"
#include <boost/python/module.hpp>
#include <boost/python/def.hpp>
#include <boost/python.hpp>
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(MakeDll)
{
class_<World>("World")
.def("greet", &World::greet)
.def("set", &World::set)
;
}
编译报错如下：

又抓了个现行

LZ应该在知道上提了一问吧

是少了Boost.Python的lib文件吧
VC的编译错误提示也和gcc一样瞎眼
