Qa_fft_filter make test failed - seg fault

GNU Radio
1

How can we diagnose make test failures? All tests passed initially, but
I
had GRC disabled, so I recompiled everything w/ GRC enabled and this
test
failed.

Also, is there a way to re-compile just parts of gnuradio, instead of
recompiling everything?

99% of tests past, only qa_fft_filter failed on arm build ubuntu 13.10
from
source.

How should I go about diagnosing these problems? Launch GDB and see
whats
happening? Strange that this is the only test that failed.

Ken,

have you read:
http://gnuradio.org/redmine/projects/gnuradio/wiki/TutorialsDebugging?

Run ‘ctest -V -R fft_filter’ to activate verbosity and limit the tests
by a regex.

Also, is there a way to re-compile just parts of gnuradio, instead of
recompiling everything?

The make system will do this for you. If you change a file, it will
compile only the minimum necessary set.

There currently open issues w/ ARM. I’m not sure this is one of them,
but VOLK code on ARM is curently heavily under research.

How should I go about diagnosing these problems? Launch GDB and see
whats happening? Strange that this is the only test that failed.

You can do that, but in general, starting with some print statements is
usually more helpful (use ctest -V). I’d wait until someone from the ARM
experts has had a look at this.

Also, when reporting bugs, especially on an ARM chip and with things
that might be VOLK related, please tell us the version of GNU Radio
you are using. If you are cloning via git, let us know the current
revision. There’s work going on to address issues related to ARM and
VOLK on certain platforms, so that could make a big difference.
