 maralorn | The haskell library ghc-internal is a core package and thus included in the package db from our ghc derivation. | 22:32:41 |
| maralorn | What is most likely broken is building the nix derivation for an independent ghc-internal package. | 22:33:34 |
| maralorn | But that has no use anyway because it is either the bundled version or an incompatible version. | 22:34:09 |
| maralorn | Because of this there should be a ghc-internal = null; file in a configuration-ghc-....nix file in nixpkgs. | 22:35:16 |

| maralorn | Manually specifying the dependency versions in your nix derivation is probably a bad idea. | 00:35:59 |
| maralorn | You are overriding the base version. That is not gonna work. | 00:37:24 |
| maralorn | You get this specific error because you are picking base_4_20 which is apparently a derivation which exists in nixpkgs but currently has no use and depends on the broken ghc-internal. | 00:38:33 |

I don't know if I was right to suggest that | 14:29:59 |
 sterni (he/him) | probably a good idea although we haven't seen a lot of fixes to 9.10 so far, so it's not comprehensive, really | 17:38:42 |
| sterni (he/him) | damn it's depressing seeing other people's overlays for e.g. 9.10 support that just never get contributed back upstream | 17:39:55 |

| alexfmpe | Man, the amount of .nix churn there was on the reflex/obsidian ecosystem | 17:56:54 |
| alexfmpe | Just for CI | 17:56:59 |
| alexfmpe | Imagine lazy evaluation as a task prioritization strategy | 17:57:29 |
