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
