swig官方学习笔记（c++ and python）

test.cpp

#include <iostream>
int go() 
{
        std::cout << "GOGOGOG" << std::endl;
        return 0;
}

int main(int argc, char **argv) {
    go();

}

test.i

 %module test
 %{
 /* Put header files here or function declarations like below */
 extern int go();
 %}
 
 extern int go();

编译

swig -python test.i

g++ -fPIC -c test.cpp -I/home/tools/Python-2.7.9/Include/ -I/home/tools/Python-2.7.9/

g++ -fPIC -c test_wrap.c -I/home/tools/Python-2.7.9/Include/ -I/home/tools/Python-2.7.9/

g++ test_wrap.o test.o -I/home/tools/Python-2.7.9/Include/ -I/home/tools/Python-2.7.9/ -shared -fPIC -o _test.so

 测试

python

>>> import test

>>> test.go()

问题

使用swig 1.x在g++ test_wrap.c的时候报错“invalid conversion from ‘const char*’ to ‘char*”，安装新版3.x后问题解决。
