Subject: HELP: extension module
Hi I need some help with the python extension modules (Version 1.3).
I want to create my own extension module as a shared library on a powermac.
Here is what I did:
* Wrote a tiny module with just one function (source is included at the end.)
Source file name: "myfirstmodule.c", shared lib name: "myfirstmodule".
* Copied the CW7 PythonCore project file, removed the sources from that and
added my module source file (retained the run-time and shared lib glue stuff).
* Built the shared lib successfully and copied it to the system extension
folder.
* Typed "import myfirstmodule" in "PythonPPC" std window.
I am getting an error saying "no module named myfirstmodule".
Any clues?
