 alexfmpe | funnily enough eval of this is broken on master and on present haskell-updates, looks like something got merged very recently | 17:28:51 |
| alexfmpe | $ nix-build -A pkgsCross.ghcjs.haskell.packages.ghc912.hello
error: no C compiler provided for this platform
| 17:30:22 |
| alexfmpe | yay | 17:30:26 |
| alexfmpe | bisect was pretty quick: this broke eval: https://github.com/NixOS/nixpkgs/pull/366593 | 17:39:01 |
| alexfmpe | somehow we're getting a
ghcjs -> emscripten -> openjdk -> python -> openssl
that ends up trying to eval stdenv.cc.isGnu that then throws because there's no c compiler | 17:51:32 |

js backend is recent enough I wouldn't bother much with anything older than 9.12 mhm i actully figured it out, but i had to apply https://gitlab.haskell.org/ghc/ghc/-/merge_requests/14882 but using sed | 17:54:57 |
| magic_rb | had to add both HEAP8 and HEAPU8 | 17:55:12 |
| alexfmpe | ah ok, keep in mind I 'backported' that last week | 17:58:28 |
| alexfmpe | https://github.com/NixOS/nixpkgs/pull/451527 | 17:58:28 |
| magic_rb | ah, good to know | 18:47:06 |
| magic_rb | i need to bump nixpkgs anyway due to a broken aeson i think | 18:47:32 |
| alexfmpe | might want to bump to the commit above, at least until the eval error is sorted out | 19:20:10 |
| alexfmpe | ^ | 19:20:15 |

might want to bump to the commit above, at least until the eval error is sorted out compiling for me, still not working, but neither jsaddle nor js is working so i think im doing something very very wrong | 19:29:39 |
| alexfmpe | what does 'not working' mean | 19:30:01 |
| magic_rb | 
Download clipboard.png | 19:30:33 |
| magic_rb | same error on both js and jsaddle | 19:30:40 |
| magic_rb | 🤔 | 19:30:45 |
| magic_rb | this is miso so maybe miso is broken, ill try a different commit ig | 19:31:01 |
| alexfmpe | can you expand the error on the browser console? | 19:39:57 |
| magic_rb | rolling back miso "fixed it" i may revisit this at some point but rn i actually want to write some code 🥲 | 21:35:30 |
| magic_rb | ive been trying to get this working for the last 2 months | 21:35:37 |

 ners | I'm trying to build a project that has build-depends on both haskell-language-server and hls-plugin-api.
Getting the following error when trying to build it with Nix:
Error: [Cabal-7107]
Could not resolve dependencies:
[__0] trying: dosh-24.11 (user goal)
[__1] trying: lsp-client-0.4.0.0/installed-9paX9qIvVp6G32qMeolaRR (dependency of dosh)

[__3] fail (backjumping, conflict set: dosh, haskell-language-server, hls-plugin-api)
If I pin to nixos-25.05 it works, so it must be a recent breakage.
| 12:50:29 |
 maralorn | Well, "breakage". | 12:55:39 |
| maralorn | The problem is that we are fixing hls with an overrideScope in config…-common.nix and that overlay one is not being applied to the exposed hls-plugin-api package. | 12:57:07 |
| maralorn | More generally when somehow beating hls into compiling I generally don’t consider downstream consumers who link against it. I wasn’t aware of their existence. | 12:58:12 |
| ners | It's a thing that should work (the usage is valid) but does not. It even used to work, but has stopped working. That's by definition a breakage. :) | 13:08:45 |
