[Boost-users] unable to load the module from simple example

Hello

I have followed the simple example from the python boost wiki page:

my source file py_moddef.cc:
___________________________________________
#include <string>
#include <boost/python.hpp>

char const* greet()
{
return "hello, world";
}

BOOST_PYTHON_MODULE(hello_ext)
{
using namespace boost::python;
def("greet", greet);
}
____________________________________________

In the next step I have built the shared library

1. g++ -c -fpic -I/usr/include/python2.6/ py_moddef.cc
2. ld -G py_moddef.o -o libpy_moddef.so

The libpy_moddef.so file I have copied to the directory which next was included 
to PYTHONPATH
>>> import sys
>>> sys.path.append("the_path")

I am not able to import the module "hello_ext" defined in py_moddef.cc, but I 
am able to import each other python module from this path, so something wrong 
is with the shared library.

>>> import hello_ext
ImportError: No module named hello_ext

Please explain to me what is wrong. I will be gratefull for any help.

Best regards

Cuma
