 kjeremy | dramforever: I'm basically trying to apply https://github.com/lopsided98/nix-ros-overlay/pull/558/ and get it to cross compile | 18:00:37 |
 dramforever | ah, that makes sense | 18:01:42 |
| dramforever | i don't think self is spliced there | 18:01:48 |
| dramforever | unless it is | 18:02:02 |
| dramforever | i am currently more confused | 18:05:45 |
| dramforever | kjeremy: do you have the full log? i'm not so sure about "All the environment variables LOOK correct" now | 18:07:34 |
 emily | ok well | 18:08:54 |
| emily | overlays/overrideAttrs are immediately suspicious yeah | 18:09:03 |
| emily | I think it's not because the main package set isn't spliced and nobody knows why | 18:09:28 |
| emily | and there have been like three PRs to fix it and I don't know why one isn't merged | 18:09:35 |
| emily | or something | 18:09:37 |
| dramforever | splicing is definitely f***ed | 18:09:39 |
| emily | like you need a callPackage in there | 18:09:43 |
| dramforever | i'm surprised it even got this far | 18:10:02 |
| emily | the cool thing about splicing is how it doesn't work at all with like foo.package = foo.override { … }; | 18:10:05 |
| emily | like it only actually helps the boring easy case | 18:10:17 |
| dramforever | yeah i think the entirety of overrides.nix needs a callPackage-ification or like pkgsXY-ification | 18:10:50 |
| dramforever | In reply to @emilazy:matrix.org
I think it's not because the main package set isn't spliced and nobody knows why i think the funniest part is iirc pkgs in _module.args in nixos is spliced | 18:16:57 |
| emily | well… | 18:17:16 |
| emily | https://github.com/NixOS/nixpkgs/pull/416276 | 18:17:24 |
| emily | I spent several days being like wtf is cross NixOS just totally busted until I discovered this bug | 18:17:32 |
| emily | but yes by default it is | 18:17:47 |
| kjeremy | this didn't seem to change anything | 18:40:31 |
| emily | your whole splicing is messed up | 18:45:33 |
| emily | can you do this as not an overlay | 18:45:40 |
| kjeremy | I'm not sure. It's even worse than this in reality. This is an unholy abomination. We're a few years out of date with nixpkgs and the latest nix-ros-overlay so I'm trying to jam these packages into our older nix-ros-overlay with an overlay and then use rust from nix-unstable to compile the zenoh packages since they require a newer toolchain. Miraculously it works natively but dies horribly during cross | 18:48:11 |
| emily | uhhh | 18:49:01 |
| kjeremy | yep | 18:49:09 |
| emily | you should be happy it can build anything :D | 18:50:05 |
| kjeremy | honestly it's pretty impressive that nix can do this when non-cross | 18:50:30 |
