 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 We're a few years out of date with nixpkgs and the latest nix-ros-overlay so I'm trying to jam these packages into our older nix-ros-overlay with an overlay and then use rust from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 |

 damccull | How do I find out what "buildRustPackage" has as far as options? Like, I see it has a 'buildFeatures' option by looking at someone else's code, but does it have a buildPackages option, for instance? Where would I look to find that out?
Basically I want to specify which particular binary in the cargo.toml to build. Normally would do this with cargo build --package mybin but not sure how in the buildRustPackage helper.
