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 [1]https://wiki.gnuradio.org/index.php/TutorialsGDB On 07/12/2017 05:50 PM, Alex Homero Rivadeneira Erazo wrote: > I am using ubuntu 16.04 LTS. > > At the end of the make test, I have obtained some failures: > > 97% tests passed, 6 tests failed out of 218 > > Total Test time (real) = 142.49 sec > > The following tests FAILED: > 48 - qa_ctrlport_probes (Failed) > 59 - qa_cpp_py_binding (Failed) > 76 - qa_cpp_py_binding_set (Failed) > 124 - qa_filterbank (Failed) > 154 - qa_ofdm_txrx (Failed) > 197 - qa_fading_model (Failed) > Errors while running CTest > Makefile:61: recipe for target 'test' failed > make: *** [test] Error 8 > > Best regards, > > Alex > > > > > > > On Wed, Jul 12, 2017 at 11:46 AM, Marcus Müller > <marcus.muel...@ettus.com <mailto:marcus.muel...@ettus.com>> wrote: > > That might still give us enough debug info.
