SWIG:'module'对象没有属性'Decklist'

我在SWIG中度过了一段时间,部分原因在于缺乏可供学习的优秀C ++示例。我终于得到了第一个用SWIG编译的程序,但是遇到了麻烦。让我直接了解代码...

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    

decklist.i:

//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

但我结束了:

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

以及包含.odecklist_wrap个文件的decklist个文件的构建文件夹。

如果我在空闲时运行python并切换到此目录并且:

import decklist

我明白了:

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。但接下来是一个命令:

dl = decklist.DeckList()  

给出:

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

我做错了什么?我很沮丧。

1 个答案:

答案 0 :(得分:2)

将decklist.i更改为:

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

或者你可以宣布你的课程和此处的函数是您要导出的。
