升壓Python的Hello World示例在Python不工作，請再次

我有同樣的問題比這傢伙在這裏升壓Python的Hello World示例在Python不工作，請再次

Boost Python Hello World example not working in Python

誰解決了他的問題，沒有指示如何。那裏的帖子已經很老了，在發佈之後，我現在又創建了一個新的問題，讓它更新一些。所以...：

我的配置：Windows 8的62bits，蟒蛇2.7.3 32位，Visual Studio 2010的最終

我跟着

http://www.boost.org/doc/libs/1_53_0/libs/python/doc/tutorial/doc/html/python/exposing.html

我創建了一個win32application項目在Visual Studio中稱爲CLIB，並勾選「dll」而不是「導出符號」。

在VC++目錄中的屬性，我把：

C：\ Python27x86 \包括：C：\提升\ boost_1_53_0; $（INCLUDEPATH）

爲包括目錄和

C：\升壓\ boost_1_53_0 \ stage \ lib; C：\ Python27x86 \ libs; $（LibraryPath）

用於庫目錄。

在CLIB.cpp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) 
     ; 
}

我試圖與或不添加

#define BOOST_PYTHON_STATIC_LIB

然後我在調試模式下編譯的（成功），則輸出的.dll（或.pyd，我已經嘗試過，沒有任何成功，通過在項目的「配置屬性」中的「常規」中將.dll的目標擴展名修改爲.pyd）CLIB.dll位於一個目錄中，該目錄的路徑也添加到了PYTHONPATH中。我甚至試圖把一個空白初始化的.py在同一目錄比DLL，而且，無論我做什麼，我不能夠在python腳本做

import hello

（從新鮮要麼創建用記事本++或用32位編碼器）。所以如果有人能夠給予確切的幫助，那將是完美的。

Thx很多。

//////////////////////////編輯1 ////////////////// /////////

在此期間，我看到python 2.7與mvs2008一起編譯，所以擦掉所有東西，安裝了python 3.3，用python 3.3重建了boost和boost.python，然後重試，但是...相同的結果...

請您模塊的本地目錄中運行代碼時。你得到了什麼確切的錯誤信息？只是「找不到模塊」或更具體的東西？ – 2013-03-24 12:35:24

試過你說的，同樣的錯誤：只是「導入錯誤：沒有名爲'你好'的模塊」。在此期間，我看到python 2.7是用mvs2008編譯的，所以刪除了所有內容，安裝了python 3.3，用python 3.3重建了boost和boost.python，然後重試，但是...結果相同...您怎麼看？ – 2013-03-24 15:07:22

正如[this]（http://stackoverflow.com/a/15576882/1053968）中所述，請考慮使用['-vv']運行python（http://docs.python.org/3.1/using/cmdline .html＃cmdoption-trace-v）參數。這應該提供洞察「import」嘗試的內容。 – 2013-03-25 17:01:28

有似乎是進口之間的差異聲明，擴展模塊名稱和擴展庫名稱：

BOOST_PYTHON_MODULE宏定義模塊初始化函數。在CLIB.cpp變化

BOOST_PYTHON_MODULE(hello)

到

BOOST_PYTHON_MODULE(CLIB)

接下來，驗證結果輸出庫具有CLIB前綴。 Python3.3刪除了一些很少使用的模塊名稱變體的支持。根據documentation，我建議先嚐試一個.pyd文件擴展名，如果.pyd不起作用，則使用.dll。因此，得到的庫應該是CLIB.pyd。

最後，試圖導入擴展用的

import CLIB

代替

import hello

是的，你是對的，同時改變「你好」從 BOOST_PYTHON_MODULE（你好） { // ... } 到CLIB，而我在編制發佈模式，稱爲CLIB.pyd一個PYD文件，在一個目錄，我把我在其中也做我的python腳本一個「導入CLIB」，沒有任何成功。哼，我生氣了。 ;-)我不記得在堆棧中的哪個位置，我看到有人說，關於boost.python，如下所示：「呃，忘了它，它的代碼在藤上腐爛......」 – 2013-03-26 07:49:00

@MisesEnForce：如果重命名文件到'CLIB.dll'不起作用，那麼你可能要考慮恢復到2.7.3，以便在使用'-vv'運行時導入更加有意義的冗餘。 – 2013-03-26 12:41:04

嗯，我應該留在MVS2010嗎？我是否應該用mvsc-9.0（和python 2.7.3）重新編譯boost和boost.python？因爲在切換到3.3之前我做了所有這些，特別是因爲我想使用mvs2010，並且因爲我讀了2.7。不應該與mvs2010一起用於編譯boost.python？謝謝 – 2013-03-26 19:16:49
