It seems you solved the issue yourself.
Hm, that is strange. You're not running this via SSH or something of
the like?

As an update, I realized that in the "Options" block,
"Generate Options" was not set to WX GUI so i set it. Now the
WX GUI FFT Sink opens the Top Block, but nothing is displayed
there, I can't see any plot and it quickly fails. The only
error message that I get is:
Warning: failed to XInitThreads()
Using Volk machine: avx_32_mmx
Any ideas?
Thank you again,
Nikos
After running ldconfig I still get an error, but a
somewhat different one:
Warning: failed to XInitThreads()
Traceback (most recent call last):
File "/home/nikos/top_block.py", line 105, in

line 93, in __getattr__
return getattr(self._impl, name)
AttributeError: 'top_block_sptr' object has no
attribute 'GetWin'
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?

Marcus

Hey all,
Just to start experimenting with GNU
Radio and companion I 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 run-time
error, namely:

What could be wrong here?
