我和这里的人有同样的问题
Boost Python Hello World example not working in Python
谁解决了他的问题，没有说明如何。那里的帖子还很旧，在张贴之后，我现在在这里创建一个新问题，以便稍微改善一下。所以...：我的配置： windows 8 62bits ，python 2.7.3 32位，visual studio 2010 ultimate
我跟着
http://www.boost.org/doc/libs/1_53_0/libs/python/doc/tutorial/doc/html/python/exposing.html
我在visual studio中创建了一个名为CLIB的win32application项目，并勾选了“dll”而不是“导出符号”。
在我放置的属性的VC ++目录中：
C：\ Python27x86 \包括; C：\升压\ boost_1_53_0; $（INCLUDEPATH）
包含目录和
C：\升压\ boost_1_53_0 \阶段\ lib中; C：\ Python27x86 \库; $（LibraryPath）
用于库目录。
在CLIB.cpp中，我把
// CLIB.cpp : Defines the exported functions for the DLL application.
//
#include "stdafx.h"
#include <iostream>
#include <string>
#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(hello)
{
boost::python::class_<World>("World")
.def("greet", &World::greet)
.def("set", &World::set)
;
}
我尝试添加或不添加
#define BOOST_PYTHON_STATIC_LIB
然后我在调试模式下编译（成功），输出.dll（或.pyd，我在“配置属性”中的“常规”中将目标扩展名从.dll修改为.pyd，但都没有成功。项目）CLIB.dll在一个目录中，我的路径也加入了PYTHONPATH。我甚至试图将一个空白的 init .py放在与dll相同的目录中，而且无论我做什么，我都无法做到
import hello
（使用notepad ++或者pyscripter 32位从new创建）。因此，如果有人能提供精确的帮助，那将是完美的。
很多。

与此同时我看到python 2.7是用mvs2008编译的，所以擦除所有内容，安装python 3.3，用python 3.3重建boost和boost.python，并重试，但是......同样的结果...

如建议使用非常详细的-vv命令运行python脚本，结果如下：

答案 0 :(得分：0)
import语句，扩展模块名称和扩展库名称之间似乎有区别：
BOOST_PYTHON_MODULE宏定义了模块初始化函数。在CLIB.cpp更改
BOOST_PYTHON_MODULE(hello)
到
BOOST_PYTHON_MODULE(CLIB)
接下来，验证生成的输出库是否具有CLIB前缀。 Python3.3删除了对一些很少使用的模块名称变体的支持。根据{{3}}，我建议首先尝试.pyd文件扩展名，如果.dll不起作用，请使用.pyd。因此，生成的库应为CLIB.pyd。
最后，在尝试导入扩展时使用
import CLIB
而不是
import hello
