  • NixOS
  • macOS
  • other Linux distributions

@r-burns Thanks for fixing this, I've confirmed this builds on Linux.

@GrahamcOfBorg build cachix

[cdepillabout]

Building on Linux, so I'm merging in.

Although I'm somewhat worried that aarch64 appears to be failing.

[cdepillabout]

Oh and cc @maralorn and @peti about this as well.

[r-burns]

Fwiw I was able to build cachix on aarch64, so maybe the ofborg error was spurious. I guess we will see what Hydra thinks.

[maralorn]

I am flabbergasted as to how this could have happened.

I remember @peti distinctly saying: „Yes, the release tarball builds, so now we can merge into master.“

This override is otherwise totally fine and expected, since we had to jailbreak quite a lot of packages because of the new QuickCheck version.

[domenkozar]

Thanks for the quick fix!

[FRidh]

We have a blocking issue again https://hydra.nixos.org/build/134718815

[domenkozar]

Huh I have disabled tests a long time ago to fix that.

[domenkozar]

Ah, that's 20.09, going to fix it.

[domenkozar]

Fixed, thanks @FRidh for spotting it.
