Re: [Discuss-gnuradio] GRC on OSX?

[Josh Blum]

WX is only used with the wxgui stuff. GRC can would function fine 
without WX, or the wxgui blocks. And flow graphs can be run in a non 
graphical mode.

Basically, the test imports are all things that the Editor uses. gtk, 
pyxml... and wx for running the flow graphs. I decided on the "import 
tests" after many emails of error verbose because something like pyxml 
was not installed. Thoughts?

------------------------------------------------------

I dont know how to just inspect the python environment to "see" if a 
module exists, without importing it (or possibly doing something messy 
with PYTHONPATH).

Perhaps we can still fix this situation by deleting the module from 
sys.modules after each test import. With the GRC trunk, as is: can you 
try and change Editor.py and see if it runs:

try: __import__(module) 

------to--------

try:
   __import__(module)   
   sys.modules.pop(module) #of course, import sys at the top

Improvement?
