Hi List,
I created an issue for this on github [0]. I assume the bug manifested
itself due to a change in GRC.
Cheers

Hi Johannes - I captured the output of grcc for both polar grc files and
they can't find
polar_config
I did a search of the gnuradio tree and my home directory
find . -name polar_config\*
and I couldn't find it either.

Hi,
this is a tricky one. My assumption is, that the configurator block
tries to compute channel capacities with a complex algorithm. There is
also the BEC channel approximation, which should be called.
This whole bug is caused by some GRC changes, as far as I could figure
it out. Could you try to have a look into the python code of the block
configurator and make sure, only the BEC functions are called? This
should fix your GRC problem.
The configurator automates quite a few things regarding channel
construction and has a built-in system for cached channel capacities. I
assume something does not behave as expected here.

Hi Alex,
could you be more specific about
'When I drop the POLAR code configurator block on the canvas, the
gnuradio program turns down.'?
Does GRC quit with an error? Does it turn dark and is unresponsive? Is
there anything printed on the commandline?
Cheers

Hey, I had that problem too!
In my case, all the tests pass - I have the correct version of GSL
installed - namely 1.16
But I couldn't even load the polar grc files.
When I press open on the grc it hangs - the grc was consuming 100% of
the cpu.
Eventually I had to kill it.
I first noticed it in gnuradio-3.7.10. I'm currently running
gnuradio-3.7.12git and I just checked and the problem is still there.
And I can't generate the python code using grcc - both polar grc
examples generate errors.

Those test failures aren't great, but I think they might be bugs in the
tests.
So, OK, can't remember what you need to do under Ubuntu to get the full
Python debugging capability in GDB, but I wrote a (slightly dated,
since
the python commands have improved) tutorial on debugging crashing
Python
applications [1].
The idea is to simply execute your minimal crashing example using
gdb --args python2 /path/to/flowgraph.py
(gdb) run
<wait for crash>
(gdb) backtrace
and figure out why where how things crash. If you got a backtrace, and
don't immediately see how to proceed (hint: print a few local
variables,
if possible, using gdb's "print" command), share it with the mailing
list
Best regards,
Marcus

That might still give us enough debug info. Which Linux distro are
we talking about (or, is it Linux at all?)

Hi Marcus
At this moment, I am installing the
gnuradio 3.7.12git-171-get72c77bc from source, which is the same
that I installed with pybombs . Unfortunately, I just already
built the gnuradio with "make && make test". The gnuradio that I
had with the standard installation was gnuradio 3.7.9
Thanks
Best regards,
Alex

Hi Alex,
that does indeed sound like a bug. Things shouldn't be
crashing!
So, what's the distribution you're working with? Maybe I can
help you a bit with the debugging. If you're, at the moment,
building GNU Radio, make sure that the CMake parameters
contain -DCMAKE_BUILD_TYPE=RelWithDebInfo , so that we get
debugging symbols :)
Best regards,
Marcus

Hi Marcus
Based on your suggestion I have deleted my Nabbles account.
Respect to my problem with the POLAR code
configurator block, I checked the discussion threads, but
anyone gave a solution.
Note that this problem does not happen with
a gnuradio installed with the distribution's package manager
(standard installation). However, the problem with this
installation method is that gnuradio is not up to date and
it does not have all the blocks that I need in my work. That
is why I used pybombs to install gnuradio which has the
blocks that I need. Now the problem is that gnuradio with
pybombs does work with the POLAR code configurator block.
When I drop the POLAR code configurator block on the canvas,
the gnuradio program turns down.
At this moment, I am installing gnuradio from source. If you
have other ideas please tell me.
Thanks
Best regards,
Alex

Hi Alex,
I hope you do get an answer, but that mail from Jose is
from the
beginning of 2016 – not extremely likely.
Anyway, have you seen the other answers that Jose got?
If not: That's Nabble's fault. I never tire to repeat:
Nabble is just a terrible, terrible web frontend to use
the official GNU
Radio Mailing list.
It's not the official mailing list archive. It never
was, and it never
will be. The official way to sign up for the mailing
list is
https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
<https://lists.gnu.org/mailman/listinfo/discuss-gnuradio>
and there's a link to the official mailing list archive,
too.
I'd recommend deleting your Nabble account, and directly
signing up
under the above address with your email account. It's
really easier to
use a proper email client (eg. GMail's web frontend) and
simply the
mails than Nabble. Nabble breaks discussion threads, it
makes answers
invisible, and it has cost us hours and hours of
unnecessary work so
far. PLEASE, don't use Nabble.
Best regards,
Marcus
