How to compile my OMNeT++ model with -Wextra compiler options

It is easy to add the -Wextra compiler option to the CFLAGS_RELEASE and CFLAGS_DEBUG variable in the Makefile.inc file, but the OMNeT++ headers themselves generate a lot of unused-parameter warnings and the model's own warnings are buried between them. Is it possible to stop OMNeT++ throwing these warnings?

You can force the OMNeT++ build process to treat the OMNeT++ header files as system headers.

Add this at the beginning of the CFLAGS_RELEASE and CFLAGS_DEBUG variables in Makefile.inc: -isystem $(OMNETPP_INCL_DIR) -Wextra

It will ensure that files in omnetpp/include directory are treated as system headers and will not throw any warnings no matter what warning level you set for the model.
