I rebuilt and now it works as expected, and I can use the WX GUI Widgets, so I can confirm that these steps actually solve the problem and the
issue was indeed that dependancy.
Thanks for all your help,

Apparently module libzmq was missing, so I installed it. Now the relevant paragraph when I am running cmake is:
Configuring gr-wxgui support...
-- Dependency ENABLE_GNURADIO_RUNTIME = ON
-- Dependency ENABLE_GR_FFT = ON
-- Dependency ENABLE_GR_FILTER = ON
-- Dependency ENABLE_GR_ANALOG = ON
-- Dependency ENABLE_PYTHON = ON
-- Dependency NUMPY_FOUND = TRUE
-- Dependency WX_FOUND = TRUE
-- Enabling gr-wxgui support.
-- Override with -DENABLE_GR_WXGUI=ON/OFF
-- checking for module 'libzmq'
-- found libzmq, version 2.2.0
-- Found ZEROMQ: /usr/lib/i386-linux-gnu/libzmq.so
which probably means it would be ok, but I can't see the WX GUI components yet.
Should I re-build GNU Radio?

But how can I enable it?
I don't know, that's why I'd like to recommend running cmake yourself:
cd /home/nikos/gnuradio/build
cmake ..
Then look for the gr-wxgui paragraph.

My GNU Radio version is 3.7.6.1 and my system runs Ubuntu release 14.04.2 LTS.
I chekced the file you asked me for and the line in question is:
"ENABLE_GR_WXGUI_cached:INTERNAL=OFF", so just as it was guessed it is disabled. But how can I enable it?
Thank you again,
Nikos
Ah, ok; my mistake; the "--enabled-components" option was just added recently; getting your GNU Radio version would be nice, nevertheless, so could you run "gnuradio-config-info -v" ?
The CMakeOutput.log contained less info than I hoped; you should have a look into /home/nikos/gnuradio/build/CMakeCache.txt. That will contain the information about installed libraries and available GNU Radio components. The line you're looking for starts with
ENABLE_GR_WXGUI.
I think the easiest way to go from here is to cd into /home/nikos/gnuradio/build. You will see CMake go through all the GNU Radio in-tree modules, and test for the dependencies of each of them. Look for the paragraph related to the gr-wxgui component. Most
probably, it will tell you what is missing.
Can you also share your Linux distro and version with us (as per /etc/issue)?
The point is that as far as I can guess, build-gnuradio wasn't able to automatically install all necessary libraries. For most systems, it can, but some are just unknown to it or have seen modifications, so that auto-installation is bound to fail.

Thank you,

Do you have the diagnostics I asked you for?
Most probably, the log file that was generated during your GNU Radio compilation contains more information; it's called CMakeOutput.log and should be in <downloadfolder>/gnuradio/build/CMakeFiles/
Also, the output of "gnuradio-config-info -v --enabled-components" would be i

Hi eveyone again,
as an update to the issue I was facing, I re-built GNU Radio, just as Marcus suggested, but I still can't see the WX GUI Widgets in the Companion.
I can see the gr-wxgui folder in my gnuradio tree, but apparantly it is still not built along with the rest of the project, and I don't know what to do to make it work.
Thank you all,
Nikos
Hi Marcus,
it's probably remains from an older installation attempt I had made (using Pybombs), which failed. After that I used that script and it worked like a charm. So if I would just do a "./build-gnuradio"
from my installation directory in order to build again, it would probably work, right?
Thanks for your help,
Nikos
Hi Nikos
I downloaded and built GNU Radio from sbrac.org
ah, ok, I presume that means you used Marcus Leech's build-gnuradio script.
The only problem is that when I am searching for any WX GUI Widgets, I can only see WX GUI Static Text, WX GUI Time Panel and WX DOA Compass.
As you've already found out, this probably means that some dependencies were missing.
In fact, of the three you list, only the static text widget is part of GNU Radio itself, so what you're seeing is possibly remains of an older installation. Are you sure you don't have any gnuradio package from your linux distribution installed?
Based on a previous discussion on that mailing list I also installed WXPython (2.8) but the problem remains.
Did you re-build GNU Radio after that? Otherwise, the GUI blocks could not have been built, and installed.
Most probably, the log file that was generated during your GNU Radio compilation contains more information; it's called CMakeOutput.log and should be in <downloadfolder>/gnuradio/build/CMakeFiles/
Also, the output of "gnuradio-config-info -v --enabled-components" would be interesting.

Marcus

Hi everyone,

Any ideas?
