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。
