Can you not try the QT sinks?
If you want to stick with wxgui,
You can try the old trick of disabling OpenGL. Make and edit
~/.gnuradio/config.conf and add the lines:
[wxgui]
style = nongl

Well I made some tests and I can verify that there seems to
be nothing wrong with OpenGL in my VM, so I don't have a clue
why I can't see any results.
Hm, then the empty window usually indicates there's not
enough samples that have reached your graphical sink at all,
*or* there's something odd with OpenGL in your VM.

Yes, that was the reason I was getting the
run-time error. I did set the build options to
WX GUI in the options block (it was set to QT
GUI) previously, and now it runs. The problem is
that when the window opens I can't see any FFT
plot, it is just a blank window, and I get the
message:
Warning: failed to XInitThreads()
Using Volk machine: avx_32_mmx

That is a good sign! This looks like you're
using WX widgets, but you haven't set the
build options to WX GUI (could be "No GUI" or
"QT GUI") in the options block in your GRC
flow graph.

After running ldconfig I still get an

Is it still the case that I am
missing some library, or it is installed
elsewhere than it should?
Thank you again,
Nikos
Ah well, in that case: it seems
like you've successfully installed the
block definition XML files to a place
GRC can find them, but that does not
apply to the library you're missing
now. If "sudo ldconfig" doesn't help,
make sure that
make install
inside your gnuradio/build directory
actually is successful. If you get
errors about missing permissions, you
might want to run the command via
sudo:
sudo make install
You might also want to have a look at
gnuradio/build/install_manifest.txt,
which should list all the files that
were installed. look for a line
containing the library you're missing
-- where did it get installed to?
Where did, for example,
gnuradio-companion get installed to?
Is that the same as what "which
gnuradio-companion" is telling you?
Best regards,
Marcus

Hi Marcus,
What I meant by "able to
use", was that I was able to
find the blocks using the search
facility and put the block to a
flowgraph. I had not actually
tried to build and execute a
flowgraph containing any of
these blocks, and now that I
tried this was the result.

Nikos
Hi Nikos,
you said earlier you were able
to use WX widgets. Did you do
something in between that and
your system now not being able
to find the libgnuradio-wxgui
library?

Hey all,
Just to start
experimenting with GNU

just created a simple
flowgraph consisting of
a Signal Source Block
and a WX GUI FFT Sink
connected to it, to see
if the diagram will be
generated. I get a
