 sterni (he/him) | One option I see would be to build stage0 without libffi and gmp altogether if that's possible | 14:00:54 |
| sterni (he/him) | In any case, context is that I'm currently patching the system libffi handling slightly to special-case stage0 and I want to at least reference some issue, so would be good to have something related already, but can also open a new one. | 14:02:28 |
| sterni (he/him) | Not sure if the patch would be upstreamable though I suspect that --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). | 14:03:17 |

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 |
