Re: [gem5-users] MemTraceProbe cannot be imported successfully
Your output says:
scons: Reading SConscript files ...
Package protobuf was not found in the pkg-config search path.
Perhaps you should add the directory containing `protobuf.pc'
to the PKG_CONFIG_PATH environment variable
No package 'protobuf' found
Did you tried to set the environment variable PKG_CONFIG_PATH to point at the
directory containing protobuf.pc?
Thanks

I think this error was because of the absence of protobuf. However, I have

protoc --version

So is this a version mismatch problem?

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 import *"
I just did a clean install / build and did not have any errors.
Kind regards

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,

Re: [gem5-users] MemTraceProbe cannot be imported successfully
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 import *" I just did a clean install / build and did not have any errors.
