 Tristan Ross | Huh, Build? | 00:34:43 |
 dramforever | are the tools just in a completely different world from the rest of the kernel build system? | 00:34:57 |
| Tristan Ross | I think so | 00:35:11 |
| dramforever | https://github.com/torvalds/linux/blob/v6.6/tools/bpf/resolve_btfids/Build | 00:35:16 |
| dramforever | are these... meant to be compilable outside the kernel? | 00:35:31 |
| dramforever | lol tools/build/Makefile.build | 00:36:18 |
| dramforever | tools/: we have kbuild at home | 00:36:31 |
| dramforever | cursed | 00:37:07 |
| Tristan Ross | So my copy-paste method of rebasing didn't work lol | 00:40:04 |
| 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 |
|  @creepinson:matrix.org left the room. | 04:58:48 |
 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 |
