I am trying to create an executable which will start a python interpreter, import a module written in python, called entry.py, run its run() method and then quit. I have this part done, although I use only the C API. Now I define a boost python module like so

struct World

{

    void set(std::string msg) { this->msg = msg; }

    std::string greet() { return msg; }

    std::string msg;

};

BOOST_PYTHON_MODULE(hello)

{

    class_<World>("World")

        .def("greet", &World::greet)

        .def("set", &World::set)

        ;

}

In my  entry.py I have the simple code

import hello

def run():

    planet = hello.World()

    planet.set("howdy")

    print planet.greet()

When I run my executable, it tells me that World is undefined in the entry module. However, if in C++ I use code like this

    PyRun_SimpleString("import hello");

    PyRun_SimpleString("planet = hello.World()");

    PyRun_SimpleString("planet.set('howdy')");

    PyRun_SimpleString("print planet.greet()");

It works!

What am I doing wrong? I am attaching my (very short) code. Be advised that I am using the funky platform of Windows XP, cygwin and GCC 3.4, boost 1.33.1. That might be the problem, but I have no other platform to try this on easily.

What am I missing here?

Best,

George
