 maralorn | Huh, wild | 06:49:28 |
| maralorn | I mean that is a test dependency. Does cabal-install by default build the test suites of dependencies? | 07:03:23 |
| maralorn | I had a look at the .cabal file and it looks normalish. | 07:04:26 |
 chreekat | I wonder if nixos is a red herring. @artem.types:matrix.org you don't have any stray GHC environment files or cabal project files around, do you? | 08:01:10 |
 magic_rb | how can i create a haskellPackages set with a patched GHC? | 13:33:43 |
| magic_rb | in a devshell i get the ghc i want with:
(ghc.overrideAttrs (old: {
patches = old.patches or [ ] ++ [ ./dont-free-stable-ptr.patch ];
})).override
{ useLLVM = true; }
| 13:34:04 |
| magic_rb | but im not sure how to make haskellPackages use that | 13:34:20 |
| magic_rb | oh maybe i found it | 13:37:01 |
| magic_rb | nope, i still dont know how to do it, i tried
haskellPackages = pkgs.haskellPackages.override {
ghc = modifyGhc pkgs.haskellPackages.ghc;
};
modifyGhc applies the modifications i sent above

 Artem | chreekat: man, you made my day: it looks like the default GHC environment screwed things up | 13:59:17 |
| chreekat | Lol I knew it | 14:15:38 |

how can i create a haskellPackages set with a patched GHC? You can browse through nixpkgs around haskell-modules/make-package-set.nix and look at the function arguments you can override. | 14:28:11 |

You can browse through nixpkgs around haskell-modules/make-package-set.nix and look at the function arguments you can override. Yeah i got somewhere i think, i wont declare success till it compiles and works | 14:32:25 |
 ners | https://github.com/ners/nix-wasm/blob/main/flake.nix
As a working example, here I create a Haskell package set with the WASM GHC (and recreate the entire stdenv while I'm at it). | 14:45:32 |
| maralorn | It is much more complicated than what you are trying to do though, since it is cross-compiling. | 15:53:30 |
