Combining gdbserver with valgrind on Torizon

Technical Support

Hello,

I use two ways for debugging C/C++ in VSCode / Torizon, either using gdbserver or valgrind as follows

application.targetfiles:  ENTRYPOINT   stdbuf -oL -eL gdbserver 0.0.0.0:6502 /#%application.appname%#/#%application.exename%# #%application.appargs%#'`

application.targetfiles: ENTRYPOINT  valgrind --leak-check=full --show-reachable=yes --error-limit=no --suppressions=/home/torizon/minimal.supp -v /#%application.appname%#/#%application.exename%# #%application.appargs%#

Is there a way to combine both valgrind and gdb ?

Best regards,
Fabian

Hi @fdortu ,

Is there a way to combine both valgrind and gdb ?

I did some research and you can use both of them by using vgdb, which is already included in the valgrind package from the Debian feeds.

vgdb should be executed soon after starting valgrind, passing the port being used. For instance, your application.tagetfiles configuration could be similar to this:

ENTRYPOINT  valgrind --leak-check=full --show-reachable=yes --error-limit=no -v /#%application.appname%#/#%application.exename%# #%application.appargs%# & sleep 2; vgdb --port=6502

With the config above I was able to run a debug session with a C test program while running Valgrind.

See if this works for you.
