Re: [Discuss-gnuradio] segfault

[Marcus Müller]

Hi Michele,

if you built GNU Radio/gqrx with gcc, then the GNU Debugger might be of
immensive help.
First make sure you've built GNU Radio with debugging symbols ("cmake 
-DCMAKE_BUILD_TYPE=RelWithDebInfo  [...]"), then start gqrx in the debugger:

?> gdb $(which gqrx)
[lots of text from gdb]
(gdb) run [<enter>]

should start gqrx and run until it segfaults. then use the backtrace
command in gdb:

(gdb) bt [<enter>]

which should show you in which function call hierarchy the fault occurred.

Greetings,
Marcus

PS: don't worry about your English, it's quite fine :)
