개요

c/c++ 코드를 다른 언어에서 사용할 수 있게 바인드해주는 도구.

예제

Python

• animal.cpp

    #include "animal.h"
    
    Animal::Animal()
    : m_speed(10.0)
    {
    }
    
    float Animal::GetSpeed()
    {
      return m_speed;
    }
    
    void Animal::SetSpeed(float speed)
    {
      m_speed = speed;
    }
  

• animal.h

    class Animal
    {
    public:
      Animal();
      float GetSpeed();
      void SetSpeed(float speed);
    private:
      float m_speed;
    };
  

• animal.i

    %module animal
    %{
      #include "animal.h"
    %}
    
    %include "animal.h"
  

• Makefile - mingw in windows

    TARGET 		= _animal.pyd
    FLAGS 		= -fPIC -shared
    INCLUDE_PATH 	= -IC:\Python36\include
    LIBRARY_PATH	= -LC:\Python36\libs
    LIBRARY 	= -lpython36
    SOURCE 		= animal.cpp\
    		  animal_wrap.cpp
    
    target: 
    	swig -c++ -python -o animal_wrap.cpp animal.i
    	g++ $(FLAGS) $(INCLUDE_PATH) $(LIBRARY_PATH) -o $(TARGET) $(SOURCE) $(LIBRARY)
