Hi,

I am running through the basic examples on the boost website for embedding boost::python.

My code currently reads:

#include <iostream>

#include "./include/Python.h"

#include "./boost/python.hpp"

using namespace boost::python;

int    main(void)

{

       Py_Initialize();

       object main_module = import("__main__");

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

       object ignored = exec("print Hello world",main_namespace);

return 0;

}

The program links successfully and begins running, however an access violation occurs (NULL pointer) at the first line after "py_initialize();" when i call import("__main__");

Visual studio 2010s debugger says the exception occurs at:  line 74 in object_attributes.hpp:

inline object const_attribute_policies::get(object const& target, char const* key)

{

return python::getattr(target, key);

}

Python was built using Visual studio 2010 so i had access to the python debug library. Boost is version 1.45 and was built using :

bjam --build-type=complete msvc stage --with-python

I am linking against:

boost_python-vc100-mt-gd-1_45.lib

and

boost_python-vc100-mt-gd-1_45.dll

I have looked for soutions on the internet and have found nothing right now. Can anyone help me?

note: i am building my application in MSVC 2010, this should work though shouldn't it?
