 magic_rb | how can i pass -Werror only in a Nix build? dont see a ghcFlags | 21:54:45 |
| magic_rb | and buildFlags doesn't work | 21:54:58 |
 maralorn | magic_rb: example here: https://github.com/maralorn/nix-output-monitor/blob/9a32f32f807a4f7bc97d95606465243f293650fe/flake.nix#L50 | 22:08:31 |
| magic_rb | Thanks, i didnt think of passing it through cabal :D | 22:18:15 |
| maralorn | I have no clue if this is the smartes solution. | 22:19:27 |
| magic_rb | Hey if it works it works | 22:24:37 |
| magic_rb | It definitely wont be the dumbest/worst piece of the nix in the repo i want to put it in. I wrote that repos initial version years ago and boy was i an idiot | 22:25:22 |

 chreekat | Fun cabal fact: there's also a --ghc-options flag (with an s). Lets you put multiple, space separated ghc options in one go | 04:59:59 |
| magic_rb | the deps for microlens-mtl_0_2_1_1 are wrong, it pulls in microlens but it needs microlens_0_5_0_0 | 11:27:22 |
 Alex | In reply to @magic_rb:matrix.redalder.org
the deps for microlens-mtl_0_2_1_1 are wrong, it pulls in microlens but it needs microlens_0_5_0_0 Nixpkgs does not do dependency solving.
Try overriding the haskell package set (see the Haskell section of the Nixpkgs manual). | 15:33:07 |
| magic_rb | Yeah i just overrode it manually for the deps, just kinda weird | 15:34:40 |
| magic_rb | The versioned packages exist, but they dont depend on yeah other | 15:35:03 |
| chreekat | I believe that all the versioned packages are just there because they can be with no guarantees | 17:06:45 |
| chreekat | * | 17:06:57 |
| magic_rb | Fair fair, thought it was an oversight :) | 17:35:00 |
