Hi Sanchayan,
There's a change on RB that needs to be pushed (
http://reviews.gem5.org/r/3779/) that fixes the issue with protobuf. You
can download this change and apply it with "hg qimport <filename> && hg
qpush". For the Python issue you ran into, you can run the following
find/sed command to "fix" it. I'll get a patch for that on RB soon.
> find . -type f -not -path ".hg/*" -exec sed -i 's/env python/env
python2/g' {} +
With these two changes, I've been able to get gem5 to compile and run on
Arch without any other problems (except for hello not working, which is a
separate issue).
Cheers,
Jason
