Problem running GNU Radio 3.6.5 under Centos on X2Go Client

Hello GR,

Lately I have installed GNU radio on my local session running on a
remote
Server.
Actually I proceeded as mentioned in the gnu radio git installation
guide
The environment variables are set respectively to

$PATH:… /users/nae/gnuradio_3.6.5/bin/
$PYTHONPATH: /users/nae/gnuradio_3.6.5/lib64/python2.6/site-packages/

(stored into the ~/.bashrc file)

However I am not sure what to set next re LD_LIBRARY_PATH and make using
CPPFLAGS as in the guide

I am using a limited access session on the server and don’t know how to
set
the variables nor how to proceed the following make command of make …

$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/local/lib
$ make CPPFLAGS="-I$HOME/local/include"

1/ When I type gnuradio-companion from the terminal it give the error:

Traceback (most recent call last):
File “/users/nae/gnuradio_3.6.5/bin/gnuradio-companion”, line 24, in

import gtk
File “/usr/lib64/python2.6/site-packages/gtk-2.0/gtk/init.py”,
line
64, in
_init()
File “/usr/lib64/python2.6/site-packages/gtk-2.0/gtk/init.py”,
line
52, in _init
_gtk.init_check()
RuntimeError: could not open display

2/ When I run gnuradio-companion graphically from its icon in
/home/gnuradio_3.6.5/bin it gives the error:

Cannot import gnuradio.

Is the python path environment variable set correctly?
All OS: PYTHONPATH

Is the library path environment variable set correctly?
Linux: LD_LIBRARY_PATH
Windows: PATH
MacOSX: DYLD_LIBRARY_PATH

Any help is appreciated.

Regards,

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
