I came now a bit further with Python 3 but I'm hitting a total road-block right now with the importer in C++ which worked in Py2 but is now totally broken in Py3. In general I've got a C++ class based module which has two methods: { "find_module", ( PyCFunction )spModuleModuleLoader::cfFindModule,

I'm willing to go to Py3 but only if the solution to the problem is simpler than getting it fixed in Py2. So some questions first: - does this importlib stuff you showed there apply to C++ land (I need to fully drive it from C++ not Python code)? - is the C++ land of Py3 similar to Py2 or totally

Loading modules from files through C++

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.
