Interesting article on cross compilation in nixpkgs if you haven't seen it https://blog.obsidian.systems/compiler-bootstrapping-in-nixpkgs/ Not cross compiling ghc though 😔 | 14:04:30 |
| chreekat | ...yet | 14:15:37 |
 sterni (he/him) | maralorn: fyi https://github.com/NixOS/nixpkgs/pull/424162/commits/3ddc9cb90a53f999a1b0c3b4b7a6215973fa6df0 | 20:23:57 |
| sterni (he/him) | we should cross compile some bindists before it stops being possible :p | 20:25:18 |
 Alex | True, maybe time to try asking around again. | 21:34:49 |
 aidalgol | sterni: I figure we should probably take the oama cabal discussion here. Should I just leave it pinned to the old GHC version, or try overriding it with a newer Cabal version, or something else? | 21:55:01 |
| aidalgol | Full disclosure, I am not familiar with Haskell tooling, and only maintain oama in nixpkgs because I have a strong need for a working OAUTH credential manager that can use the Secrets Service interface. | 21:56:19 |

No guarantees that stuff will get prioritised but it might help avoid stuff falling through the cracks | 12:41:23 |

It would probably be far more effort than adding our own bindists to tarballs.nixos.org and is of limited benefit to x86 and aarch64, so I could understand if nobody wants to do it. | 15:54:29 |

Is there a specific set of issues you have in mind?

That sounds like precisely it, yes.
Maybe if I get the time I'll try applying the MR in Nixpkgs... | 17:34:35 |
| Teo (he/him) | There's also been a lot of work recently on making more boot libs easy to reinstall and on ghc-toolchain. Both of those should make everything cross related easier to implement in a nice way | 18:04:53 |

 Pierre Thierry | I'm trying to fix broken packages, starting with polysemy-zoo, I have the latest master from the nixpkgs repo, and the only files modified are broken.yaml and main.yaml in configuration-hackage2nix, but when I do:
./maintainers/scripts/haskell/regenerate-hackage-packages.sh
I get the following error:
hackage2nix: user error (Unexpected end-of-input, expecting JSON value)
Am I missing a step or doing something wrong?
| 13:53:54 |
| chreekat | So you modified json and now you're getting a "user error: invalid json"? :D | 14:17:34 |
 maralorn | Yeah, sounds like you made a syntax error in the yaml files. | 14:49:19 |
| Pierre Thierry | Well, I didn't think my changes could be the source but I checked anyway: I get the error with a clean working directory. | 16:30:42 |
| maralorn | I just checked out recent nixos-unstable and it seems to work. | 17:58:30 |

| sterni (he/him) | maralorn: do you have time to give https://github.com/NixOS/nixpkgs/pull/429212 a look over or should I just merge it and start an evaluation | 11:46:13 |

| sterni (he/him) | or others with relevant experience of course :p | 11:57:57 |
| maralorn | I can take a look later. | 12:29:00 |
| sterni (he/him) | Pierre Thierry: Feel free to open an issue about it, including enough information to hopefully reproduce the issue you're seeing. | 17:12:26 |
