No cgo zstd support on ARM?

[tylerd-canva]

I'm currently using using version 2.3.9 on linux/amd64 with zstd_implementation: cgo with no issues. I'm just testing out a new ARM CI instance and running into this error:

Unrecognized ZSTD implementation: cgo, supported: map[go:{}]

Is this a known issue? I wonder if it has something to do with cross-compiling for ARM which then maybe disables CGO? I couldn't find anything indicating one way or the other in the GitHub actions steps.

I'll give it a shot with 2.4.1 and report back.

Hmm, it works when I make a local build, but the release binary looks like it wasn't built with this enabled. I will try to fix this and replace the binaries tomorrow.

I tested with 2.4.1 as well and noticed the same issue. Is CGO used anywhere else in the codebase? I have never had good luck with cross-compiling Go when using CGO so I suspect to get this working with CI we would need GitHub Actions to support ARM runners.

I rebuilt and re-uploaded this, and confirmed that --zstd_implementation cgo works:
https://github.com/buchgr/bazel-remote/releases/download/v2.4.1/bazel-remote-2.4.1-linux-arm64

Can you try that and let me know how it goes?

I will keep this issue open until I figure out how to make this work automatically for the next release.

Yep, seems to be working. Thanks!
