Hello, Well, it turns out that I somehow removed the line imports MemTraceProbe in BaseCPU.py while trying to figure out what was wrong with protoc. Just in case someone else has a similar problem, MemTraceProbe should also be imported along with CommMonitor to attach a probe to a monitor.
Thanks and kind regards.

When I try to start the simulation, gem5 gives an error: NameError: global name 'MemTraceProbe' is not defined All the required protoc libraries are installed: libprotobuf-dev, python-protobuf, protobuf-compiler, libgoogle-perftools-dev and running "protoc --version" gives "libprotoc 2.5.0". Also gem5 does not complain about protoc libraries at the beginning of a build and build/X86/configs/have_protobuf.hh has the line "#define HAVE_PROTOBUF 1". I searched for a solution in this mailing list but could not find a solution (or the solutions suggested did not work). Anyone has any idea what might be the problem? Thanks and kind regards.
