Public bug reported:
Created a simple model with a file source and waterfall sink to check a
recorded signal's frequency. When I ran the model, I got the following
error:
----
The xterm executable '' is missing.
You can change this setting in your gnuradio.conf, in section [grc],
'xterm_executable'.
(This message is shown only once)
----
xterm is installed and "which xterm" says that it's at /usr/bin/xterm .
GNU Radio should detect xterm when being installed, set the necessary
setting and run without errors.
Also, the error message seems to be misleading (targetting a different
distribution?): I don't have a gnuradio.conf, but I do have a
/etc/gnuradio/conf.d/grc.conf which will probably do the trick.
In other words, a manual workaround is to edit grc.conf as suggested in
the error message, but a user should not have to do this.
