 Tristan Ross | But the original PR just works basically | 00:40:12 |
| Tristan Ross | 🤷 | 00:40:27 |
 dramforever | oh i didn't realize you were testing a PR
| 01:22:05 |
| Tristan Ross | I'm picking up development of the PR, I hope to fix it in 25.05 | 04:54:32 |

 Grimmauld (any/all) | wait can't i use pkgsCross to compile from aarch64 for x86_64-linux? | 06:57:46 |
 K900 | You can unless cross blows up | 06:57:57 |
| Grimmauld (any/all) | its not listing as something in the attrset | 06:58:57 |

| K900 | It's pkgsCross.gnu64 | 06:59:51 |
| K900 | The subset names are stupid | 06:59:56 |
| Grimmauld (any/all) | huh | 07:00:21 |
| Grimmauld (any/all) | thanks | 07:00:23 |
| Grimmauld (any/all) | time to test whether i can build apparmor as cross now | 07:01:51 |
| Grimmauld (any/all) | I am working on https://github.com/NixOS/nixpkgs/pull/400430
Everything works, except apparmor-pam. That one doesn't find the pkg-config things. It was broken before too, i didn't break it - but i'd love to fix it! Any ideas? | 09:41:41 |

| Grimmauld (any/all) | is this because it tries to run target pkg-config instead of build machine pkg-config, maybe? | 09:53:03 |

| Grimmauld (any/all) | Ok, might be fixed | 10:03:55 |
|  tealquaternion joined the room. | 13:27:04 |
 emily | we set PKG_CONFIG etc. variables for cross | 13:44:17 |

yeah, marcin-serwin saw the issue and i got it fixed | 13:48:38 |
| Grimmauld (any/all) | Now all of apparmor supports cross, LLVM, and Musl | 13:49:20 |
| emily | packaging looks clean, nice | 13:54:56 |
| Grimmauld (any/all) | Thank you, better than whatever this was: https://github.com/NixOS/nixpkgs/blob/nixos-unstable/pkgs/os-specific/linux/apparmor/default.nix
But i do expect some review to still come along and request some change because of some oversight. Building my system against this is not viable as it rebuilds systemd and dbus | 14:05:41 |
| emily | there comes a time in every Nixpkgs contributor's life where they must purchase a Big Computer | 14:06:20 |

 @rosssmyth:matrix.org | I have a job that runs my builds against latest unstable each weekend, and this weekend the bump from GCC 14.2.1 20241116 to GCC 14.2.1 20250322 has changed something with relocations as I now get a bunch of dangerous relocation: unsupported relocation. Mainly because relocations are not supported on the target I used (arm-embedded, armv6-m), but I pass in hardeningDisable = [ "all" ];. I expected something to break due to the bump based upon that issue about GCC breakage, but not this. Anyone have any ideas what may have changed? | 16:42:03 |
