利用boost在C++中嵌入python

示列代码

#include <iostream>#include <python2.4/Python.h>#include<boost/python.hpp>using namespace std;using namespace boost::python;int main() {Py_Initialize();PyRun_SimpleString("from time import time,ctime/n""print 'Today is',ctime(time())/n");Py_Finalize();return 0;}

编译时在连接选项中加入-I python2.4

目前环境是centos5.5,python为自带安装的2.4版本

 

 

按照boost开发指南上封装Python对象

//pyinit.hpp#include<boost/noncopyable.hpp>#include<boost/python.hpp>class pyinit: boost::noncopyable {public:pyinit(int initsigs = 1) {assert((initsigs == 1)||(initsigs == 0));Py_InitializeEx(initsigs);}~pyinit() {}bool IsInitialized() {return Py_IsInitialized();}static void err_print() {PyErr_Print();}const char* version() {return Py_GetVersion();}};

 

#include <iostream>#include <python2.4/Python.h>#include<boost/python.hpp>#include<string>#include"pyinit.hpp"using namespace std;using namespace boost::python;int main() {pyinit pinit;object s("sa");string str = extract<string> (s * 5);cout << str << endl;string execstr = "print 'abc'";try {exec(execstr.c_str());}catch(...) {pyinit::err_print();}return 0;}

 

 

 

编译：g++  -o"test111"  ./src/test111.o   -lpython2.4 -lboost_python

由于开始没有加上-lboost_python，结果弄了半天老报错
