How to use Valgrind to debug omnetpp

[felix4U]

Hi OMNET-Community,

i discovered several memory leaks in my simulation and now i want to
use valgrind in order to find them.

I use the following command to start a memory check, however the
omnetpp.ini can´t be found:

valgrind --leak-check=yes ./out/gcc-release/src/inet -c
myconfiguration -r 0 -u Cmdenv

End.

Furthermore i want to mention that the omnetpp.ini - file isn`t in the
same folder than my inet-Executeable. It is different from this
example (http://groups.google.com/group/omnetpp/msg/1cdc08939d06e6c9).
How can i define the target of "myconfiguration"? -myconfiguration is
a configuration of the omnetpp.ini file. The "omnetpp.ini" is located
in the following directory: myinetmanet/scenarios/testscenario/
omnetpp.ini

Greetings,
Felix

If you do not provide the location of the omnetpp.ini explicity it is assumed to be in the current working directory. From your command line it seems that your current working dir is the root of the INET project which surely does not contain any omnetpp.ini file.

I suggest change to the directory where your omnetpp.ini is present and change the path to the inet executable accordingly.

ps: as a side note, the 4.2b1 ide contains direct support for valgrind. (simulation should be started in the Profile As... menu)

Hi Rudolf, Thank you for your hints. I updated omnet to Version 4.2b1 and at the moment Valgrind does a great Job! Hopefully i can find the errors... Regards Felix
