Re: [Discuss-gnuradio] Problem using GRC when executing the grc examples

[Josh Blum]

The error says:

GRC generates the python files in the directory that the .grc file is 
found. Since the examples are installed in a root owned part of the file 
system /usr/share, you do not have permission to create files there as a 
regular user.

Just open the file in grc and do a save-as in into your user home 
directory. Then try to run the flow graph.
