Describe the bug

the haskellPackages.haskell-language-server package doesn't seem to build for aarch64-darwin.

Here's the job log on Hydra: https://hydra.nixos.org/build/155006253/nixlog/1. It looks as though the issue is to do with the ormolu package?

Steps To Reproduce

nix-env -iA nixpkgs.haskellPackages.haskell-language-server.

Expected behavior

HLS builds.

It also doesn't build for nixos 21.05: https://hydra.nixos.org/build/154147571

That’s an unrelated issue. That probably was a hardware/environment problem. I have restarted that build job in the hopes that it succeeds on the next run.

Hey @hexagonal-sun, thx for the report. That build error looks quite weird and baffles me. I have also restarted that one, maybe it was a weird glitch … (Edit: didn‘t help)

Sadly I don‘t have a system for testing or the time to support aarch64-darwin.

Of course we will gladly accept any PRs fixing this and I can try to give input/feedback into attempts to debug this.

I had exactly the same error when hasskell-ide-ingine was building locally after nixpkgs update, so it seems indeed broken.

Oh, okay. I can reproduce. Thank’s for the report. Will fix this asap.

Will be fixed by #140518.

Now back to the original topic. Sorry for the noise.

haskell.compiler.*: mark as unsupported on aarch64-darwin
e3beb7c 
While GHC now can be bootstrapped and built on aarch64-darwin, it seems
to work only to an extent. All sorts of strange issues have manifested
themselves in `haskellPackages` and downstream usage which leads me to
conclude that it would be misleading to call it supported on this
platform, especially in a stable channel. To give a few examples,
separate bin outputs just don't work in general [1] and `opt` fails
for unknown reasons in some derivations [2]. As I don't own any
appropriate hardware, I have tried tackling these issues by staring into
my crystal ball, but so far to no avail (even worse, new issues [3] have
cropped up due to changes that should have been an improvement).

Given these circumstances, I'm not willing to call GHC supported on
aarch64-darwin for the stable channel. I'm (for now) hopeful that we can
improve the situation on `master` going forward, but it is not
guaranteed that these changes will be backportable without a ton of
effort.

Should it turn out that we can't resolve these issues or maintain GHC's
aarch64-darwin support due to a lack of contributors going forward, I am
also prepared to drop aarch64-darwin support completely. While it has
been proclaimed a Tier 3 platform, I would argue that the “popular”
package GHC has never been working, at least not properly.
