[Discuss-gnuradio] GRC on OSX?
I'm trying to run ./Editor.py on the latest GRC SVN trunk on OSX 10.4.10 (checked out as of this morning).

1) I suppose numbersink2 is not in your particular gnuradio build. Checkout the trunk again. 2) There is no config file when you first load GRC. When you close GRC, it will create the config file, and the error will be gone thereafter. 3) Bus Error? I have no idea... There are no un-intialized variables.

Does GRC using WX for anything until running a flow-graph? I assume it's included because of the scopes and such in gr-wxgui?

Re: [Discuss-gnuradio] GRC on OSX?
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? -Josh Michael Dickens wrote: Does GRC using WX for anything until running a flow-graph?
