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, but a somewhat
different one:

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.

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?
