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 error,

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.
Greetings,
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 Radio and companion I
just created a simple flowgraph
consisting of a Signal Source

connected to it, to see if the
