Does it also happen on a ~2 weeks old commit? This might be https://rust-lang.zulipchat.com/#narrow/channel/131828-t-compiler/topic/Changing.20static.20linking.20of.20rustc.20to.20LLVM.20to.20dynamic/with/575767894.

[Kivooeo]

Yep, I have a macOS Sequoia 15.6 and can confirm it

[RalfJung]

Yep, I have a macOS Sequoia 15.6 and can confirm it

As in, it's already broken 2 weeks ago?
But surely if building rustc main on macOS was entirely broken or 2 weeks we'd have heard about it. So there must be something specific to your setup that breaks it?

[Kivooeo]

I tried it first time today, before this I was working only in dev desktop

As for setup I just cloned https://github.com/rust-lang/rust and ran ./x b

[Kivooeo]

if building rustc main on macOS was entirely broken or 2 weeks we'd have heard about it.

but yeah, I agree with this, it's odd

[jieyouxu]

I'm trying locally on aarch64 macos against 69b7853

[jieyouxu]

I can reproduce with a compiler profile (arm64 macOS 26.2), no download-ci-rustc.
