I had been running version 22, and I had also run the bootcamp 2022 example for
demonstrating MESI_Two_Level protocol. After I upgraded to version 23.0.0.1, I
first noticed that I had trouble compiling the example. After finding a work
around, to generate gem5.opt, The program seems to be missing the parameter
processor (which was not needed when I ran version 22. I can use some
suggestions on how to run this example with the new version (What has changed?
The example where it worked in version 22, but not in version 23:
scons build/NULL_MESI_Two_Level/gem5.opt --default=NULL PROTOCOL=MESI_Two_Level
-j16
The program gave me an error:
scons build/NULL_MESI_Two_Level/gem5.opt --default=NULL PROTOCOL=MESI_Two_Level
-j16
scons: Reading SConscript files ...
You're missing the pre-commit/commit-msg hooks. These hook help to ensure your
code follows gem5's style rules on git commit and your commit messages follow
our commit message requirements. This script will now install these hooks in
your .git/hooks/ directory.

It is strongly recommended you install the pre-commit hooks before working with
gem5. Do you want to continue compilation (y/n)?
y

However if I run the following:
python3 `which scons` build/NULL_MESI_Two_Level/gem5.opt --default=NULL
PROTOCOL=MESI_Two_Level -j16
The program generates gem5.opt
Unfortunately, I also get the following error when I try to run gem5.opt:
