c++ - SWIG: 'module'对象没有属性 'Decklist'

我在SWIG上度过了一段艰难的时光，部分原因是缺乏可借鉴的C++示例。我终于有了第一个使用SWIG进行编译的程序，但是在运行该程序时遇到了麻烦。让我直接看一下代码...

setup.py:

#!/usr/bin/env python

"""
setup.py file for SWIG example
"""

from distutils.core import setup, Extension


decklist_module = Extension('_decklist',
                           sources=['decklist_wrap.cxx', 'decklist.cpp'],
                           )

setup (name = 'decklist',
       version = '0.1',
       author      = "Me",
       description = """Testing!""",
       ext_modules = [decklist_module],
       py_modules = ["decklist"],
       )

decklist.hpp:

#include <boost/unordered_map.hpp>



class DeckList{
   private:
        boost::unordered_map<std::string, int> mainBoard;
        boost::unordered_map<std::string, int> sideBoard;
    public:
        void addCard(std::string name, int cardCount);
        int getCount(std::string cardName);
        DeckList();
        ~DeckList();

};

decklist.cpp:

#ifndef DECKLIST_H
#define DECKLIST_H
#include "decklist.hpp"
#include <stdio.h>

DeckList::DeckList(){

}

void DeckList::addCard(std::string cardName, int cardCount){
    mainBoard[cardName] = cardCount;
}

int DeckList::getCount(std::string cardName){
    return mainBoard[cardName];
}

#endif

卡套 list :

//decklist.i
%module decklist
%{
    #include "decklist.hpp"
%}
#include "decklist.hpp"

现在在终端上(我在Ubuntu Natty Narwhal上)，我运行以下两个命令:

swig -python -c++ decklist.i
python setup.py build_ext --inplace

第二个给我以下回应:

running build_ext
building '_decklist' extension
gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fPIC -I/usr/include/python2.7 -c decklist_wrap.cxx -o build/temp.linux-x86_64-2.7/decklist_wrap.o

但我最后想到了:

decklist.cpp
decklist.hpp
decklist.i
decklist.py
decklist.pyc
_decklist.so
decklist_wrap.cxx
setup.py

and a build folder with .o files for both the decklist_wrap and decklist files.

If I run python in idle and switch into this directory and:

import decklist

我得到:

Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
      import decklist
ImportError: No module named decklist

奇怪的是，如果我从终端运行它，我可以import decklist。但是然后是一个命令:

dl = decklist.DeckList()

给出:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'DeckList'

我究竟做错了什么？我很沮丧

最佳答案

更改decklist.i，如下所示:

//decklist.i
%module decklist
%{
    #include "decklist.hpp"
%}
%include "decklist.hpp" // <-- *** use % in *.i  ***

或者，您可以在此处声明要导出的类和函数。
