-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Naceur,
the display error looks like the result of the X Window display environment variable not being set. Assuming that you run your gnuradio-companion command from a terminal started from within your X Session, this is strange.If echo $DISPLAY does not give something like :0, try export DISPLAY=:0 gnuradio-companion Of course, if you try to run a graphical program such as gnuradio-companion on a terminal-only session (eg. ssh connection to a server), you won't have any success. What you can do is set up a trusted X tunnel, by running ssh with -X -Y flags. Note, however, that there is little sense in running the companion on a server. What you'd usually do is run gnuradio-companion on your local workstation, build non-graphical flowgraphs, and run these on the server. Hope that was kind of insightful, Marcus On 14.01.2014 16:40, Naceur wrote: > Hello GR, > > Lately I have installed GNU radio on my local session running on a > remote Server.
