1 개요

C/C++로 쓰여진 코드를 Perl, Python과 같은 하이레벨 언어에서 사용할 수 있도록 래퍼 코드를 생성해주는 유틸리티.

2 설치 (윈도우즈)

1. 배포본을 다운로드받아 적당한 곳에다 풀고 디렉토리 이름을 설정한다. (설치 프로그램이 따로 없다.) 이 디렉토리를 $(SWIG)라고 하자.
   
2. $(SWIG) 디렉토리를 패스에다 추가한다. 물론 매번 실행 파일의 패스를 지정할 것이라면 상관없다.
   
3. PYTHON_INCLUDE 및 PYTHON_LIB 환경 변수를 설정한다.
   

   PYTHON_INCLUDE = C:\python23\include 
   PYTHON_LIB = C:\python23\libs\python23.lib

Template2doc 라이브러리를 파이썬용으로 포팅하기.

다음의 테스트 코드를 만족하도록 template2doc.i 파일을 수정하고 실행하시오. 새로운 typemap을 정의하여야 합니다.
