[pygtk] Embedding Python

[Peyman]

Hi




simulator.sh is the script I run to compile and execute the C program.
simulator.c the main C program which calls the Python interpreter.

global_variables.py contains some global variables



Can anyone shed some light as to what this means.

Also, to make the C program work you have to update the full file paths.

Cheers


Peter

I am trying to embed a Python script (creates a PyGtk window) in C. I can get it to work, except when I try to import a module I created. I have attached a simple example which shows what the problem is test_dialogue.py is a simple python script which launches a window, and two dialogs. In test_dialog.py, line 16 ('import global_variables') is commented out. If I uncomment it, I get an exception: " 'No module named global_variables' in 'garbage collection' "
