Hello,
Could you try locating the protoc bin and setting the environment PROTOC to it?

Hello Serhat,
Thank you for your reply. After I rebuilt gem5, the following error message
prompted:

Perhaps you should add the directory containing `protobuf.pc'

I think this error was because of the absence of protobuf. However, I have
installed protobuf,
***
protoc --version
libprotoc 3.9.0
***
So is this a version mismatch problem?
Best,

Hello,
If you are using the recent versions of gem5, you should use:
***
from m5.objects.CommMonitor import *
from m5.objects.MemTraceProbe import *
***
instead of "from <module> import *"
I just did a clean install / build and did not have any errors.
Kind regards
Serhat

Subject: [gem5-users] MemTraceProbe cannot be imported successfully
Hello,
I am trying to have a monitor between the CPU and L1 Cache, so for
src/cpu/BaseCPU.py, I edited the function "addPrivateSplitL1Caches":
...
#self.dcache_port = dc.cpu_side
self.monitor = CommMonitor()
self.monitor.trace = MemTraceProbe(trace_file="trace.txt")
self.dcache_port = self.monitor.slave
self.monitor.master = dc.cpu_side
..
I got an error: 'MemTraceProbe' is not defined
Then, I imported CommMonitor and MemTraceProbe in BaseCPU.py
However, MemTraceProbe cannot be imported successfully.
How to solve this problem?
I will appreciate any help.
Best regards,
Rosen
