Next, when you want to build with this repository, use the `--gem5-source` argument to point this repository to the private source code:
Next, when you want to build with the private repository, use the `--gem5-build-dir` and `--gem5-source-dir` argument to override our default gem5 source and build locations:
....
cd linux-kernel-module-cheat
./build-gem5 \
--gem5-build-id private/master \
--gem5-source "$gem5_internal" \
--gem5-build-dir "${gem5_internal}/build" \
--gem5-source-dir "$gem5_internal" \
;
./run-gem5 \
--gem5-build-id private/master \
--gem5-source "$gem5_internal" \
--gem5-build-dir "${gem5_internal}/build" \
--gem5-source-dir "$gem5_internal" \
;
....
With this setup, only the private gem5 build outputs are stored in this repository, and they are safely gitignored.
With this setup, both your private gem5 source and build are safely kept outside of this public repository.
