Re: [Discuss-gnuradio] Fwd: Random test failures when compiling GNURadio from source

I've noticed the same on our buildbot setup (and wanted to address this for a while). `qa_packet_format` is another candidate which seems to randomly fail. Also compiling on buildbot seems to fail sometimes randomly because of `M_SQRT2` or `M_LOG2E` undeclared errors.

So, Kevin, without having a deeper look I assume the tests need to be revised. I'm also glad to have a look as soon as I find some time. Maybe we can accumulate faulty tests within this thread and start working from there.

Best,

Hello,

We have been trying to compile and run GNURadio from source and the make tests have been failing randomly.

Machine Details

Intel NUC (x86-64 machine)

Ubuntu 16.04.03

GNU Radio version 3.7.11

gcc version 5.4.0 20160609

Commands used

git clone --recursive https://github.com/gnuradio/gnuradio

git checkout v3.7.11

mkdir build

cd build

cmake -DENABLE_GR_QTGUI=OFF -DCMAKE_INSTALL_PREFIX=/usr/local ../

make -j4

make test

Out of every 4 compilations, 1/2 would fail the make test e.g qa_constellation_receiver(attached error with email) or
qa_ofdm_sync_sc_cfb. Our fix so far has been to re-run the build with no modifications and the tests pass.

I have seen similar errors pop up in the mailing lists and the cause is usually incorrect setting of seed.
e.g https://lists.gnu.org/archive/html/discuss-gnuradio/2012-04/msg00318.html

Does this issue still persist? or known?

Kevin
