 maralorn | Well builds also need to succeed of course. | 14:21:22 |
| maralorn | well compare pkgs/top-level/release.nix (ctrl+f haskell) with pkgs/top-level/release-haskell.nix | 14:26:42 |
 Profpatsch | Is there a shortcut for building an executable with pre-set GHC RTS params? | 14:26:49 |
| Profpatsch | In particular -Iw60 for small scripts to reduce the idle gc frequency | 14:27:04 |
| maralorn | Yes, you can pass RTS flags to set by default to ghc. | 14:27:27 |
| maralorn | e.g.: -with-rtsopts=-maxN2 | 14:28:01 |
| maralorn | * e.g.: ghc-options: -threaded -with-rtsopts=-maxN2 | 14:28:28 |
| Profpatsch | Ah you mean in the cabal file? | 14:28:43 |
| Profpatsch | I guess that works | 14:28:46 |
| maralorn | According to that we mainly build every ghc major release+hls on master and plenty more on haskell-updates. | 14:30:16 |
| alexfmpe | Huh so the darwin build is probably failing is that it? | 14:42:16 |
| maralorn | Oh, no. | 14:45:15 |
| maralorn | I think because of reasons which I would largely summarize under "Apple" we currently don’t build for any darwin target on haskell-updates. 😄 | 14:45:53 |
| maralorn | That was however a temporary mitigation for that fact that stuff was very fragged. I don’t know what would need to happen for us to re-enable them. | 14:47:05 |

Ah you mean in the cabal file? The alternative, if you don't want to touch the Cabal file, is that you edit the cabal2nix output or override the package.
I think --ghc-options can be added to configureFlags? | 14:49:31 |
| Profpatsch | cabal file is fine | 15:03:05 |

Maybe what you're thinking of is packageOverrides: https://haskell4nix.readthedocs.io/frequently-asked-questions.html#how-to-override-packages-in-all-compiler-specific-package-sets So I would set it in my overlay, right? | 15:40:53 |
| Las | this is just what I wanted | 15:41:01 |

 hellwolf | error: attribute 'doctest_0_23_0' missing

Did you mean doctest_0_24_0?
when using haskell.packages.ghc912.haskell-language-server
| 20:00:18 |
| hellwolf | patched locally, trying to build it now | 20:10:01 |
| maralorn | Probably a good idea to do the recommended fix in nixpkgs. 😄 | 20:10:10 |
| hellwolf | :) let's see if it builds, then I will send a PR | 20:10:42 |
| hellwolf | fwiw,
``
$ git grep doctest_0_23_0
pkgs/development/haskell-modules/configuration-nix.nix: { inherit (super) doctest doctest_0_23_0; }
pkgs/development/haskell-modules/configuration-nix.nix: doctest_0_23_0;
Does it mean, we would build with different doctest for different ghc versions?
| 20:11:14 |
| hellwolf | * fwiw,
$ git grep doctest\_0\_23\_0
pkgs/development/haskell-modules/configuration-nix.nix: { inherit (super) doctest doctest\_0\_23\_0; }
pkgs/development/haskell-modules/configuration-nix.nix: doctest\_0\_23\_0;
