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 <module>
tb = top_block()
File "/home/nikos/top_block.py", line 56, in __init__
self.GetWin(),
File "/usr/local/lib/python2.7/dist-packages/gnuradio/gr/hier_block2.py",
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?
Greetings,
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?
Thank you,
