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. -- Cinaed > > > On 12.07.2017 18:04, Marcus Müller wrote: >> 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.
