@jclulow, it looks like /opt/go/bootstrap/bin/go on this builder is an earlier build of go1.18. That's not going to work: the meaning of the current go1.X build tag changes as the release is developed, so an earlier development build of go1.18 will try (and fail) to build files tagged //go:build go1.18 that use APIs added later during development.

The bootstrap Go compiler really needs to be a stable release of some sort. (Maybe install Go 1.17.2 instead?)

$ mote run /opt/go/bootstrap/bin/go version
go version devel go1.18-a2a9a7b513 Tue Aug 17 21:34:32 2021 +0000 illumos/amd64

@golang/release: the illumos-amd64 builder is currently broken, and needs to have a different bootstrap toolchain installed or configured.

@jclulow is the owner of the illumos-amd64 builder listed at https://farmer.golang.org/builders, and I understand the only one able to resolve this issue. Please let us know if someone else can help.

I agree with the suggestion of using Go 1.17.2 as the bootstrap, as that is both stable and satisfies proposal #44505. Go 1.16.9 would also work well as a bootstrap version.

Change https://golang.org/cl/354695 mentions this issue: cmd/cgo: use "!compiler_bootstrap" tag instead of "go1.18"

Sorry about that, I'll get it sorted today!

Thanks very much @jclulow!

The issue affecting cmd/cgo and causing a visible failure was fixed via CL 354695, which is why this issue is closed now, but updating the illumos-amd64 builder to use a stable Go 1.16 or 1.17 release will still be helpful and appreciated, as it can avoid similar problems in the future and improve our confidence in the test results. Thanks again!

Thanks for continuing to build/test on illumos! We're a small community but we very much appreciate it.

OK, I believe I have sorted that out:

root@gobuild1:~# /opt/go/bootstrap/bin/go version
go version go1.17.2 illumos/amd64

Please let me know if there are any other issues with the builder and I'll get right on it.

@jclulow, unfortunately it looks like there is something wrong with the go1.17.2 install: the builds appear to be failing with status 1 during bootstrapping. 😞

Oh no! I will take a look.

OK, so, the first 1.17.2 bits were built on my Linux workstation using the bootstrap script, with a clone of the tree at the 1.17.2 tag. I'm not sure why those don't work.

I've replaced them with a native (on illumos) build of 1.17.2 from the official source archive at golang.org. When I built it, it told me ALL TESTS PASSED so hopefully it is alright!

I'll check in on the build jobs tomorrow. Sorry about the mess!

Looks like it's passing now. Thanks for persevering!
