@emilazy:matrix.orgemily also, target support is not solely in std. 16:05:04
@andrew15_5:matrix.orgAndrewthis is what fenix tells16:05:30
@andrew15_5:matrix.orgAndrew what is pkgsCross? 16:09:55
@emilazy:matrix.orgemily pkgsCross.<system> is a Nixpkgs configured for cross-compiling to that system. 16:10:37
@andrew15_5:matrix.orgAndrewAnd which package I need to install for those targets?16:11:37
@emilazy:matrix.orgemily probably pkgsCross.<system>.buildPackages.rustc 16:12:26
@andrew15_5:matrix.orgAndrewwell damn, 2600 MiB is kinda a lot16:17:47
@andrew15_5:matrix.orgAndrewAnd it also builds something? Why is that?16:18:17
@andrew15_5:matrix.orgAndrew builds llvm-19.1.7 16:18:29
@andrew15_5:matrix.orgAndrewnot in the nixos cache?16:19:04
@emilazy:matrix.orgemilycross build packages get rebuilt for the new target. for some things that's dumb and should be fixed though, like LLVM16:20:43
@andrew15_5:matrix.orgAndrewso you're saying there should be a cache for llvm?16:21:24
@andrew15_5:matrix.orgAndrewI'm not sure if you build the build tools for different target, how would I then be able to use them to build the program for that target if those build tools are not for my host target.16:23:02
@emilazy:matrix.orgemily they are rebuilt for a different --target, but the same --host. 16:23:18
