 magic_rb | nice | 11:29:54 |
| magic_rb | we shold have a UPX post build hook thing | 11:30:16 |
| magic_rb | this is actually nice, writeHaskell actually creates a equally small binary | 11:48:02 |

 sterni (he/him) | MangoIV: will you need htree for GHC < 9.10 going forward? | 10:39:36 |
 MangoIV | No. this is intended.. Thank you for pining but since this has come up the second time now, I think I'm registered for maintainer, let me just fix it if it breaks in the future. :) | 10:41:18 |
| MangoIV | (don't want you to be blocked on things like this :3) | 10:41:32 |
| sterni (he/him) | MangoIV: well we're far from blocking on anything, I was just cleaning up some stuff | 10:50:39 |
| sterni (he/him) | Would be great if someone could look into this since there is no known fix yet https://github.com/typeclasses/chell/issues/5 | 10:50:54 |

 Marc Jakobi | Has anyone else noticed a significant increase in memory when compiling Haskell packages with ghc 9.8.4 compared to ghc 9.6.6? I haven't been able to pinpoint it yet and I can't reproduce it outside of nix builds. | 09:45:42 |
 ners | Does this happen on the same nixpkgs pin, e.g. nix build nixpkgs#haskell.packages.ghc984.rhine vs nix build nixpkgs#haskell.packages.ghc966.rhine? | 10:09:07 |
| Marc Jakobi | In reply to @ners:nixos.dev
Does this happen on the same nixpkgs pin, e.g. nix build nixpkgs#haskell.packages.ghc984.rhine vs nix build nixpkgs#haskell.packages.ghc966.rhine? It doesn't even happen for all packages. I'm trying to build the same package with ghc 9.6, but it's failing to build singletons-th (or singletons-th_3_5), which is one of the dependencies - which kind of adds to my suspicion that this may be a template-haskell regression. | 14:28:51 |
| Marc Jakobi | Yep, no matter how I try to override or jailbreak packages, I can't seem escape dependency hell if I use another ghc version. | 15:13:23 |
 Teo (he/him) | Are you able to reproduce this outside of nix? Might be good to open a GHC ticket if you can confirm it's a GHC issue | 15:31:08 |
