Hi Aditiya,
[Putting on the list so other people can benefit too]
It is not required to add any 'include' header in src/cpu/BaseCPU.py. The
reason you are getting this error is because scon build system hasn't
compiled the CommMonitor code. You should see this as a WARNING during scon
build process that protobuf iss missing. SCON checks for google protocol
buffer on your system and if scon doesn't find it then 'have_protobuf' is
set to '0' and CommMonitor is not included in the build repo. You have to
install google protobuf then set PROTOC environment variable to the
installed dir.
Then you need to rebuild gem5 as:
scons -j6 build/X86/gem5.opt
This time scon will build all the CommMonitor classes and you won't see any
errors like '"NameError: global name 'CommMonitor' is not defined"'
Caution: I set the PROTOC environ variable in the shell but still scon
doesn't pick it up. One way of getting around this is to change SConstruct
and provide the protoc path as '/usr/bin/protoc' instead of reading from
environment variable:
('PROTOC', 'protoc tool', "/usr/bin/protoc"),
Hope this helps.
Best Regards, Ahmad
