[boost] Problem running with PyRun_File()

13 Jul 2004

      Hi,

I am having problem when running the following c++ code. The system
tells me "Unhandled exception ....":

(I also tried running PyRun_String with the string identical to
strings in hello.py, and it worked fine.)

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
#include <boost/python.hpp>
#include <iostream>

using namespace boost::python;

int main ()
{
    Py_Initialize ();

    object main_module (handle<> (borrowed (PyImport_AddModule("__main__"))));

    object main_namespace = main_module.attr ("__dict__");

    std::string filename = "hello.py";

    FILE *fp = fopen( filename.c_str(), "r" );
    if (fp == NULL)
    {
        std::cerr << "failed to open file" << std::endl;
        return -1;
    }

    handle<> (PyRun_File (
        fp
        , const_cast<char*>(filename.c_str())
        , Py_file_input
        , main_namespace.ptr()
        , main_namespace.ptr()));

    fclose(fp);

    Py_Finalize ();
    return 0;
}
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

(Here is the content of hello.py:)
####################
hello = file('hello.txt', 'w')
hello.write('Hello world!')
hello.close()
####################

Can anyone point me what do I need to get it running. Thanks very much!
