 emily | interesting thanks | 14:13:07 |
| emily | to be clear I wouldn't even be that upset if it doesn't work with splicing :P | 14:13:35 |
| emily | just so long as you can actually reasonably access it across platforms | 14:13:49 |
 tpw_rules | i'm getting fc-cache> /nix/store/qil3nqnisxb8kmpjfp3i50wgfgdbhh76-qemu-user-10.0.3/bin/qemu-aarch64: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory when trying to cross build my ISO now. looks like hostPlatform.emulator might be broken somehow? https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/libraries/fontconfig/make-fonts-cache.nix | 15:49:55 |
| tpw_rules | now as in after yesterday's staging merge | 15:50:06 |
| tpw_rules | (it could also be that suddenly my iso needs fontconfig which is broken, it really shouldn't, but it's broken regardless) | 15:50:25 |
 Artturin | Same issue here | 15:51:37 |
| tpw_rules | okay so maybe it's just my deps changed and that's been broken for a while | 15:52:54 |
 Grimmauld (any/all) | no, i think i did my build on staging-next that time | 15:53:15 |
| Grimmauld (any/all) | cross doesn't get much caching, so might as well build against staging-next | 15:53:35 |
| tpw_rules | oh dang. i might try to just revert the qemu upgrade then | 15:53:41 |
| tpw_rules | did you get any further on a diagnosis? | 15:54:27 |
| Artturin | Tester

| Artturin | nix build -f test.nix cacheCross | 16:02:55 |
| Artturin | At 72f5bfc3b5338a608e268fa867d4706dec66fd25 cacheCross still builds, on master it faild | 16:03:48 |

| Artturin | (Just a random rev from my one of my PR branches) | 16:04:21 |
| tpw_rules | i have some spare CPU cycles, i can take some shots in the dark and then bisect. thanks for the reproducer | 16:04:43 |

| Artturin | Sus | 16:06:51 |
| Artturin | Because withPackages discards splicing | 16:07:06 |
| Grimmauld (any/all) | oh that looks like splicing hell | 16:07:11 |
 dramforever | yup that's dead | 16:07:32 |
| Grimmauld (any/all) | https://github.com/NixOS/nixpkgs/issues/211340
nvm no need to tell you, you are well aware | 16:07:35 |
| Artturin | Well easy fix and doesn't need to go to staging | 16:07:34 |
| Artturin | I'll make a pr | 16:07:39 |
| dramforever |
# Don't change this to python3 and python3.pkgs.*, breaks cross-compilation
| 16:08:00 |
| dramforever | evidently, not enough | 16:08:06 |
| Grimmauld (any/all) | just python3Packages.distlib ? | 16:08:48 |
| dramforever | pkgsBuildHost.python3Packages... I think? | 16:09:35 |
