@wiomoc I was wondering if we should move the bazel rules into its' own repository. I suggest bazel-ocx. Further, regarding a compiler package, would ziglang be a good starter? Maybe sccache as well?

I was wondering if we should move the bazel rules into its' own repository.

I think that would make the most sense in the long run; I’d already had that in mind - but for the first draft, the repo seemed like the most seemed approach to me. Feel free to create an extra repo for this

Further, regarding a compiler package, would ziglang be a good starter?

The Zig compiler can be used for both Zig and C (as a Clang frontend). As for the former, we can certainly tackle that; it seems fairly straightforward when I look at rules_zig. For C, however, more complex steps are apparently required, which is why I would postpone that for now.

sscache

i don't see any usecase why one should use sscache inside bazel

I would also consider the Bazel module's API to be unstable for now, since additional features in OCX might make it necessary to redesign the API again - I am thinking of layers or dependencies.
