Gazelle fails on macOS when using apple_support and go version 1.22+

[redsun82]

When defining this minimal MODULE.bazel:

module(name="foo", version="0.0")

bazel_dep(name = "apple_support", version = "1.15.1")
bazel_dep(name = "gazelle", version = "0.36.0")
bazel_dep(name = "rules_go", version = "0.47.0")

go_sdk = use_extension("@rules_go//go:extensions.bzl", "go_sdk")
go_sdk.download(version = "1.22.0")  # also with versions 1.22.1 and 1.22.2

and creating the usual BUILD.bazel:

load("@gazelle//:def.bzl", "gazelle")

gazelle(name = "gazelle")

then when I bazel run //:gazelle I get

Target //:gazelle failed to build

Commenting out either the apple_support dependency or using a lower go version works ok.

If it helps, I'm running this on an M1 macOS, with bazel version 7.1.1. Funnily enough, bazel build @gazelle//cmd/gazelle builds ok, so it seems this is only happening when building it [for tool].

Also, running with --@rules_go//go/config:pure is a workaround, but it's not ideal as I have the feeling it then runs quite slower.

[redsun82]

See github/codeql@b0758fd for a workaround based on using the 1.21.9 go toolchain just for gazelle on macOS.

I've been running into this for weeks now as well. I'm in a codebase where we must include apple_support in order to drive rules_apple, but also have some custom Gazelle functionality to support other kinds of programs. We are stuck on Go 1.21 until this is corrected, workarounds notwithstanding.

The only research I've managed to do with my limited knowledge of rules_go and the Go linker is that the output from --subcommands between Go 1.21 and 1.22 is identical. As far as I know, there is more behavior within the builder wrapper that occurs before or as part of the linker being invoked, so this is probably not very illuminating.

Which version of Xcode are you on? I think I saw similar error messages on Slack and this was resolved by just updating to the latest version.

[aaronsky]

I am on the latest stable release, Xcode 15.3. Using --xcode_version_config to aid in discovery.

Which Slack messages are you referring to? I am here via this.

Seems like this may be an upstream problem: uber/hermetic_cc_toolchain#171

[ewhauser]

This caused by the -dead-strip flag in rules_apple_support. See this PR: bazelbuild/apple_support#309

and this Slack thread: https://bazelbuild.slack.com/archives/CDBP88Z0D/p1715173028271439

Discovered yesterday while experimenting with Go 1.22.5 that this does not occur for me anymore. Xcode 15.4, apple_support 1.15.1, rules_go 0.48.1 and latest gazelle. Not sure it will make a difference for y'all, but maybe something upstream changed that's working for me?
