OpenBSD arm64 support

[ikmckenz]

I'd love an arm64 version for OpenBSD, looks like there is an arm64 version for FreeBSD so hopefully the effort is minimal?

[evanw]

Can you verify that esbuild builds and runs on that configuration? For example: installing Go, downloading this repo, and running go test ./internal/... to verify that basic tests pass?

[ikmckenz]

Looks good to me! It builds and the tests seem to pass. Full output of the Go tests:

And this is on OpenBSD on an Arm MacBook:

openbsd-dev$ uname -a
OpenBSD openbsd-dev.my.domain 7.4 GENERIC.MP#2273 arm64

[evanw]

That's great, thanks!

Currently testing the cross build in this branch: https://github.com/ikmckenz/esbuild/tree/openbsd-arm64, but ran into a weird issue with Go. I think there may be an issue with go cross building to OpenBSD arm64, as even hello world fails to run correctly. Issue filed with Go here: https://github.com/golang/go/issues/66040

[ikmckenz]

Issue was the Go cross compiler not working correctly for OpenBSD on the latest (M2+) apple silicon chips, but when tested against an M1 it was always working without issue. The M2+ issue has also been resolved upstream in go. To that end I've opened a pull request for my branch here: #3674

[ikmckenz]

Hey @evanw , is there anything else I can do to support this?

[ikmckenz]

Thank you! :)
