[python-win32] Re: genpy and py2exe

[Erignac, Charles A]

I set  win32com.__gen_path__ to 'C:\Temp\gen_py' through the GenPath registry key. Also made sure that the path was in sys.path. This setup works fine from python.exe. Unfortunately fron the py2exe package I still get an ImportError when loading a wrapper :(.

If I understand correctly, you are running makepy (or genpy) from within
the packaged program?

If this is so, there are 2 problems:
- where will the generated files be created, and how can you determine
  this directory,
- how do you import these files.

For the first problem, you should read the win32all code, and experiment
with the exe.
Foe the second problem, IIRC, you don't need a custom importer
(probably). The exe-file still can import from the file system, just add
the directory to sys.path.
