ubuntu中python调用C/C++方法之动态链接库详解

这里使用：

sudo apt-get install libboost-all-dev

服务端

序列化后发送

main.cpp:

#include <iostream>
#include "libUO.h"
 
int main()
{
 UO_C_Socket t;
// t.StartSocketServer("",4121);
 boost::thread t1(boost::bind(&UO_C_Socket::StartSocketServer,&t,"",4121));
 sleep(2);
// boost::thread t2(boost::bind(&UO_C_Socket::StartSocketClient,&t,"127.0.0.1",4121));
 
 
// t2.join();
 t1.join();
 return 0;
}

客户端

客户端在UO_BaseFun.h里实现基本功能，将其进行封装并通过boost_python导出。特别注意，这里BOOST_PYTHON_MODULE中的名字需和最后make出的so文件

同名，不然会出现错误，错误名字忘记了

UO_libdll_py_wrap.cpp：

#include <boost/python.hpp>
#include <boost/python/module.hpp>
#include <boost/python/def.hpp>
#include "UO_BaseFun.h"
 
 
BOOST_PYTHON_MODULE(UO_BaseFun) //python模块
{
 // boost::python::class_<UO_C_Socket,boost::noncopyable>("UO_C_Socket")
 boost::python::class_<UO_C_Socket>("UO_C_Socket")
 .def("StartSocketClient",&UO_C_Socket::StartSocketClient)
 // .def("getname",&student::getname)
 // .def("setage",&student::setage)
 // .def("getage",&student::getage)
 // .add_property("name",&student::getname,&student::setname)
 // .add_property("age",&student::getage,&student::setage)
 ;
}

特别注意的是makefile中编译和连接的区别，其中出现的未定义符号错误需加上动态链接库-lboost_filesystem等。出现找不到pyconfig.h错误需包含

-I/usr/include/python2.7。make完了之后生成UO_BaseFun.so文件

makefile：

UO_BaseFun.so:UO_libdll_py_wrap.o
 g++ UO_libdll_py_wrap.o -o UO_BaseFun.so -shared -fPIC -L/usr/lib/x86_64-linux-gnu\
 -lboost_filesystem -lboost_thread -lboost_serialization -lboost_python -lboost_system
 
 
UO_STR.o:
 g++ -c UO_STR.h -o UO_STR.o -I/usr/include/boost \
 # -lboost_serialization 
 
UO_BaseFun.o:UO_STR.o
 g++ -c UO_BaseFun.h -o UO_BaseFun.o -I/usr/include/boost \
 # -lboost_system -lboost_filesystem -lboost_thread -lboost_serialization
 
UO_libdll_py_wrap.o:UO_BaseFun.o
 g++ -c UO_libdll_py_wrap.cpp -o UO_libdll_py_wrap.o -fPIC -I/usr/include/python2.7
 # -lboost_serialization
 
 
clean:
 rm -rf UO_STR.o O_libdll_py_wrap.o UO_BaseFun.o
 rm -rf UO_BaseFun.so

验证

UO_StoreSystem_py.py：

 import UO_BaseFun
test = UO_BaseFun.UO_C_Socket()
test.StartSocketClient("127.0.0.1",4121)
