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 We're a few years out of date with nixpkgs and the latest nix-ros-overlay so I'm trying to jam these packages into our older nix-ros-overlay with an overlay and then use rust from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 |
| emily | anyway any time you nativeBuildInputs you must explicitly use buildPacakges | 18:50:45 |
| emily | since no splicing | 18:50:51 |
| kjeremy | Okay! So I got it to use the right packages by using buildPackages.{rustPlatform, cargo, rustc}. It turns out I had to tell zeno to pass the right architecture down to cmake with cmakeFlags = [ "-DZENOHC_CUSTOM_TARGET=aarch64-unknown-linux-gnu" ]; | 20:06:51 |
