Problems with example from bootcamp 2024
I am attempting to do the example from 2024 bootcamp described in the charts, and also in the README.md file located at:
2024https://github.com/gem5bootcamp/2024/tree/main/materialshttps://github.com/gem5bootcamp/2024/tree/main/materials/03-Developing-gem5-modelshttps://github.com/gem5bootcamp/2024/tree/main/materials/03-Developing-gem5-models/06-modeling-cache-coherencehttps://github.com/gem5bootcamp/2024/tree/main/materials/03-Developing-gem5-models/06-modeling-cache-coherence/README.md
The charts give one set of instructions, however the README.md appears to be from bootcamp 2022. Is there an updated README? After following the 2024 chart directions, I am getting the following error when trying to build:
scons -j17 build/X86/gem5.opt PROTOCOL=MyMSI

I want to put this exercise in a lecture to my computer architecture class, but I can't get past the build process. Unfortunately, the lecture on this topic from bootcamp never made it into youtube.
Any help would be appreciated.

Hi Nick,
I think there's another typo: "My_MSI.slicc" != "MyMSI.slicc"
Apologies if the bootcamp documentation is inconsistent. If you see
inconsistencies in the upstream bootcamp, it would be great to open an
issue on that repo.
Cheers,
Jason

Jason,
Sorry to bother you with this, but after I changed MyMSI.slicc to My_MSI.slicc I was able to compile the code, how ever I got the following error when I tried to run (His is with the complete files used)
[ CXX] src/base/date.cc -> ALL_MyMSI/base/date.o
[ LINK] -> ALL_MyMSI/gem5.opt
scons: done building targets.

fatal: This system assumes MyMSI from learning gem5!
Now the original files had MyMSI.slicc. Is it possible that the code really wanted the slicc file without the underscore, and there is a problem that requires it? Where in the code would it look for My_MSI.slicc?
I did not see anything in kconfig.

That corrected the bug. The file in the completed directory did not have the underscore.
Thank you,
