Bazel build fails on Big Sur

[kdeding]

Following the instructions on README to build github/semantic on MacOS Big Sur (with bazel 4.0.0 or 3.0.0), I got the following errors.

After googling around, tried this command: bazel build --copt="-Wno-error=execute_or_fail_loudly" //.... But it didn't help at all.

Have been stuck on this for the last two days. Would appreciate any help to get around this, because this library can really help me do what I want to.

Many thanks, Kurt

I got the build working using cabal. I suppose it's just bazel that gives the trouble.

Hmm, interesting. Might be worth trying to upgrade the version of rules_haskell that we target; I don’t think Big Sur had come out when we last updated it, and it looks like there is some problem with the GHC bindist. Is this running on Apple Silicon?

Thanks for the tip. My machine is an Intel MacBook Pro.
