after embedding and extending python (using swig) problem importing (non-core) modules

Du you use program in linux? I work in windows, but I think it's a way to tell your program the module path like this:

 char path[MAX_PATH], cpy_cmd[MAX_PATH];
 GetCurrentDirectory( MAX_PATH, path );
 sprintf( cpy_cmd, "sys.path.append(r\'%s\\modules\')", path );
    PyRun_SimpleString("import sys");                // load built-in module sys
    PyRun_SimpleString( cpy_cmd );  // set my modules path
