 hexa | probably the heaviest package among them | 13:53:56 |
| hexa | aarch64-darwin still looks pretty bleak | 13:54:15 |
| hexa | so I wasn't in a hurry | 13:54:20 |
| hexa | we are also basically ouf of work for the darwin machines with ~5k left queued | 13:54:45 |
| hexa | whereas linux has 33k and 43k | 13:55:03 |
| hexa | e.g. ffmpeg-headless and MoltenVK | 13:56:16 |
 K900 | There's a PR with bulk lld fixes somewhere | 13:56:47 |
 whispers [& it/fae] | https://github.com/NixOS/nixpkgs/pull/537712 has moltenvk | 13:57:46 |
 emily | oh didn't see that there was another one | 13:58:05 |
| emily | urgh I am so sorry about how much this is hitting | 13:58:13 |
| emily | the temporary in-tree workarounds aren't too bad, but I have a fear that tons of people's downstream builds are going to break | 13:58:31 |
| emily | Myria: re the wrapped Swift, does that mean that Swift itself fails to link programs, not just Swift itself fails to link? | 13:59:46 |
| emily | maybe we should just be introducing an ld64-fixed and using that where necessary :/ | 14:00:04 |
| emily | will merge for now and we can figure out Swift later | 14:01:20 |
| emily | I've hit the button, so should be able to get more Darwin work with an eval. Swift will still block stuff it sounds like though. I will hopefully have some more time to look at aarch64-darwin later tonight | 14:02:24 |
| emily | maybe should add some stuff to ld64 passthru tests that would have caught this regression… but I guess if we're switching to LLD anyway it won't be relevant for long | 14:02:55 |
| emily | do we know what's up with ffmpeg? | 14:04:07 |
| emily | I can spend maybe 15 minutes looking at that now if not | 14:04:21 |

ERROR: gmp not found\

| hexa | https://hydra.nixos.org/build/334103643/nixlog/2 | 14:07:41 |
| emily | yeah, I mean… what's actually up :) | 14:07:53 |
| emily | since it is getting gmp as a build input | 14:07:59 |
| emily | I'm looking now | 14:08:01 |
| hexa | hah, no :D | 14:08:05 |
| hexa | I can quickly try to repro outside build infra | 14:08:35 |
| hexa | repros on community builder | 14:09:23 |
