I'm using Python in an embedded situation. In particular I have to load python scripts through a memory interface so regular python module loading can not be used. I got working so far a module loader object I've added using C++ to sys.meta_path . Now I'm totally stuck at the finally loading step.
I've got this a C++ loader method "load_module(fullname)" which does load the requested module script files into a null-terminated string. I know that "load_module" has to return the module PyObject*. But I can't get the python source in the c-string into a module PyObject*. I've tried so far this: #CODE# return Py_CompileStringFlags( content.GetString(), lookupPath.GetPathNative(), Py_file_input, NULL ); #CODE# This did not result in a module that worked. In particular the module script in question contains a method "create". Using "dir(module)" on the returned value I see no "create" method and the type is a compiled string. So I tried this: #CODE# loadedModule = Py_InitModule3( fullname, NULL, "Loaded module" ); if( ! PyRun_StringFlags( content.GetString(), Py_file_input, loadedModule, loadedModule, NULL ) ){ if( PyErr_Occurred() ) PyErr_Print(); Py_INCREF( Py_None ); return Py_None; } Py_INCREF( loadedModule ); return loadedModule; #CODE# I concluded that I have to create the module myself and somehow eval/compile the c-string into the module. For this I figured out PyRun_StringFlags would be a suitable candidate. But doing the above I get an error: #CODE# Traceback (most recent call last): File "<string>", line 22, in <module> ImportError: __import__ not found #CODE# Looks like builtins are not existing. But from the internet I read that if code is parsed from a module both globals and locals are the module. The above code should do this but yet it fails. I tried also with PyEval_GetGlobals() and PyEval_GetBuiltins() I had no luck either except the function complaining about receiving NULL values. Can anybody help how in gods name one is supposed to create a module from an in-memory c-string when called from within load_module (or anywhere)? -- Yours sincerely Plüss Roland Leader and Head Programmer - Game: Epsylon ( http://www.indiedb.com/games/epsylon ) - Game Engine: Drag[en]gine ( http://www.indiedb.com/engines/dragengine , http://dragengine.rptd.ch/wiki ) - Normal Map Generator: DENormGen ( http://epsylon.rptd.ch/denormgen.php ) - As well as various Blender export scripts und game tools
