c++ python交互之boost.p

我们做的项目测试代码用的是python，但是由于开发用的代码是c++，所以很多交互的地方是需要python调用c++的代码。为此我们将c++的函数打包成.so文件被调用。在实际项目中会遇到各种类型的应用，项目组的郭松同学做了比较详细的总结。我将之收集成文，记录如下，便于自己以后翻阅，也为自己博客添砖加瓦，感谢的话就不说了，如果有朋友因为这篇文章受益，请感谢小松同学。

1.普通函数转换

#include <iostream>
#include <string>
using namespace std;


char const* testA()
{
return "just a test";
}

string testB(string str)
{
cout << str << endl;
return str;
}

void testC(string str,int num)
{
cout << "str is : " << str << endl;
cout << "int is : " << num << endl;
}

python 转换代码: class="lazy" data-src4py.cpp

#include <boost/python.hpp>
#include "class="lazy" data-src.cpp"
using namespace boost::python;
BOOST_PYTHON_MODULE(test) //test是python中模块名字
{
def("a", testA);//将testA映射为a 函数
def("b", testB);
def("c", testC);
}

因为是第一篇将makefile也展示一下，后面文章将不记录Makefile,因为都一样。/usr/local/boost_143/include/是事先必须准备的库文件。

all:test.so
rm -rf class="lazy" data-src.o class="lazy" data-src4py.o
rm -rf cass_pack_factory_class="lazy" data-src.o cass_pack_Factoryclass="lazy" data-src4py.o

test.so:class="lazy" data-src.o class="lazy" data-src4py.o
g++ class="lazy" data-src4py.o -o test.so -shared -fPIC -I /usr/local/python/include/python2.5/ -I /usr/local/boost_143/include/ -L /usr/local/python/lib/python2.5/ -L
/usr/local/boost_143/lib/ -lboost_python
class="lazy" data-src.o:
g++ -c class="lazy" data-src.cpp -o class="lazy" data-src.o

g++ -c class="lazy" data-src4py.cpp -o class="lazy" data-src4py.o -fPIC -I /usr/local/python/include/python2.5/ -I /usr/local/boost_143/include/

clean:
rm -rf class="lazy" data-src.o class="lazy" data-src4py.o
rm -rf test.so
