But with this info, I’m not sure. That’s not an error that GNU Radio is
gnuradio companion. But as before if I execute the python script companion
and that could be annoying. May also be a problem if trying to
remotely log in and run the app.
I just ran into Scott’s problem.
The problem is not that gnuradio-companion’s popen() of …/top_block.py
is failing, it’s that the popen() of the xterm executable, xterm, is
gnuradio-companion tries to open an xterm when you have a “No GUI” top
$ sudo yum install xterm
solved the problem for me.
