 emily | we backport patches for newer LLVM support to older GHCs | 19:52:34 |
| emily | (there aren't that many, the backend doesn't change much since it uses the LLVM textual IR format) | 19:52:52 |
| emily | (mostly it's just backporting bumps to the version number it checks) | 19:53:02 |

 iqubic (she/her) | What should I do if Nix is refusing to build a Haskell Library for me? Right now, hip is failing to build! https://hackage.haskell.org/package/hip | 03:30:09 |
| iqubic (she/her) | error: Package ‘hip-1.5.6.0’ in /nix/store/aqhcr0kv7d91rfm0ca77rbakjk5gkbq6-source/pkgs/development/haskell-modules/hackage-packages.nix:330406 is marked as broken, refusing to evaluate.
a) To temporarily allow broken packages, you can use an environment variable
for a single invocation of the nix tools.
$ export NIXPKGS_ALLOW_BROKEN=1
Note: When using `nix shell`, `nix build`, `nix develop`, etc with a flake,
then pass `--impure` in order to allow use of environment variables.
b) For `nixos-rebuild` you can set
{ nixpkgs.config.allowBroken = true; }
in configuration.nix to override this.
c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
{ allowBroken = true; }
to ~/.config/nixpkgs/config.nix.
note: trace involved the following derivations:
derivation 'mh26'

 aiya | when you get that message, most likely it's a compilation error. try running NIXPKGS_ALLOW_BROKEN=1 nix-shell -p haskellPackages.hip to isolate the error | 02:03:47 |
| aiya | here's the error i got when running that command: | 02:04:06 |
