 sterni (he/him) | * Not sure if the patch would be upstreamable though I suspect that, currently, --with-system-* does not work when building a cross compiler with anything but Nix and with Nix it's sometimes broken if the headers are platform specific (i.e. libffi). So maybe it would be a net positive. | 14:03:39 |

| sterni (he/him) | alexfmpe: Alex: https://github.com/NixOS/nixpkgs/pull/501983 so this is my idea, just letting cc wrapper deal with stage0 (since we're in stdenv anyways) | 16:30:59 |
| sterni (he/him) | gonna clean that up, patch doesn't seem too terrible to maintain, may even be upstreamable in some shape or form | 16:31:27 |
 Teo (he/him) | I'm not sure if there's an existing issue. Creating one sounds great! https://gitlab.haskell.org/ghc/ghc/-/merge_requests/15231 might cover this but I'm not sure.
Even if it's just nix specific it would be good to have it upstream since then we'd be less likely to break downstream all the time.

 alexfmpe | do we have any idea what causes the rts configure error mentioned in
https://github.com/NixOS/nixpkgs/pull/482251#issuecomment-3779413252 | 18:25:28 |
| alexfmpe | I also hit it for s390x | 18:25:33 |
| alexfmpe | * affects some powerpc variants, i686, s390x | 18:25:59 |

 aiya | say I wanted to fix a C++ lib that is relevant for a haskell package (i.e. fix libtorch to fix libtorch-ffi), would that be done in the haskell-updates branch or another branch? | 17:18:26 |
| alexfmpe | Usually haskell-updates is for LTS bump related shenanigans. If your error is present on master and can be fixed there, usually that's what you want | 17:27:14 |
| alexfmpe | Unless it causes mass rebuilds, then it goes on staging | 17:27:34 |
| aiya | i don't understand, i thought haskell-updates was for all Haskell package changes? | 17:28:00 |
| aiya | * i don't understand, i thought haskell-updates was for all Haskell package changes? or are you specifically talking about non-haskell packages | 17:28:09 |
| sterni (he/him) | it's a development branch for haskell related changes, but that doesn't mean that it needs to be used in every case | 22:37:26 |
| sterni (he/him) | we were stricter about this in the past, but due to workflow changes going via haskell-updates means changes don't see master for weeks | 22:38:17 |
