Re: [Discuss-gnuradio] GRC on OSX?

[Michael Dickens]

Maybe it's the use of python 2.5?

Has anyone (on this list, or if you know someone) ever used GRC on  
OSX?  As I said, I've never tried to until this morning.

Done.  Nothing changed.

OK.  I went ahead and did "touch ~/.grc.xml", which makes that  
message go away.  No change in execution.

Running gdb comes back with:
