You can track when #353383 will reach master here:

I didn't know such a site existed. Thanks for letting me know.

What's a good way to find out the last working commit in cases like this?

[emilazy]

hydra-check can help you narrow it down. In this case it would be the last commit before the #348827 staging-next cycle was merged, containing #346043. OTOH, that fixed much more than it broke on macOS.

[cpick]

It looks like staging-next was merged a few hours ago, but (if I’m reading hydra correctly) I believe the resulting evaluation unfortunately still has a broken zig build on darwin.

[cpick]

I’m thinking I may be confused?
The staging-next build of zig.aarch64-darwin succeeded three days ago, but when that was merged into master a few hours ago the resulting evaluation still contained the zig.aarch64-darwin job that failed 15 days ago?

[haruki7049]

Hey @cpick, Did you try nix build github:NixOS/nixpkgs/774183fcfe0583c03008b54995c5c2a1467ea762#zig?

I tried this command, then this command successed.

 - system: `"aarch64-darwin"`
 - host os: `Darwin 24.1.0, macOS 15.1`
 - multi-user?: `yes`
 - sandbox: `no`
 - version: `nix-env (Nix) 2.18.2`
 - channels(root): `"nixpkgs"`
 - nixpkgs: `/nix/store/63lvc59rjz075kb1f11xww2x2xqpw1pn-source`

If you successed to run the command, the cause might be happened by Hydra.
