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
Johannes

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
