Farshid,
Are you getting this warning when you run scons to build gem5?
"Warning: did not find protocol buffer library and/or headers.
Please install libprotobuf-dev for tracing support."
If so, I have some ideas on how to fix that. I don't know what distro your
running, but on CentOS, for example, the protobuf package installed by yum
doesn't install all the necessary files (bug 815587 was filed at EPEL for
this problem over two years ago, but it hasn't been fixed yet). Because of
this, I had to download protobuf from Google and build it. There are a some
gotchas (at least for me) when setting this up, so if you need any tips
with getting that to work, please let me know.
It looks like you are using a Debian flavor of Linux. I don't believe I've
tried the protobuf package on a Debian-based system, so I don't know if the
Debian package works. If you are getting the above warning when building
gem5, then likely the answer is "no."
Hope this helps,
Patrick
