Hi Azadeh, It sounds like you’ve got something wrong with the comm_monitor.cc file. Make sure you have the appropriate version (hg revert src/mem/comm_monitor.cc). Also, you do not need to change the comm monitor to trace packets. It’s already part of its functionality.

Now I do not need to trace them. So I replaced the modified BaseCPU.py and comm_monitor.cc files with the original ones. However, when I compile gem5 with the following command: scons build/X86/gem5.opt -j2 I get the following error: build/X86/mem/comm_monitor.o: In function `CommMonitor': /home/azadeh/gem5/build/X86/mem/comm_monitor.cc:59: undefined reference to `vtable for CommMonitor' /home/azadeh/gem5/build/X86/mem/comm_monitor.cc:59: undefined reference to `vtable for CommMonitor' collect2: ld returned 1 exit status scons: *** [build/X86/gem5.opt] Error 1 scons: building terminated because of errors. I would really like to know how I can have a successful compile again and would appreciate any help.
