I investigated the issue, and the root-cause is that https://github.com/uutils/coreutils/blob/90609044ebc8a6802bb2aef05c57600b4de5af1e/src/uucore/src/lib/features.rs#L42 disables utmpx when building uucore for the musl target, as a work-around for uutils/coreutils#1361
The reason this was done is that the libc crate has not implemented functions like "endutxent" for musl (this file needs to be modified: https://github.com/rust-lang/libc/blob/master/src/unix/linux_like/linux/musl/mod.rs).

Is there a way to disable the build of uutils-coreutils for musl in yocto, so that the PR is unblocked? Or is the implementation of uutils-coreutils for musl a pre-requisite?

[kraj]

its fine to disable it for musl. Perhaps do

COMPATIBLE_HOST:libc-musl = "null"

although it will be good to inform upstream rust libc about this problem and see if it can be fixed and tracked.

[Ecordonnier]

I added the line you recommended to disable musl. I also created a ticket at libc to track the issue: rust-lang/libc#3190

Is there some CI which tries to build all recipes with musl, and will fail because of the following error when trying to build with musl?

ERROR: Nothing PROVIDES 'uutils-coreutils' uutils-coreutils was skipped: incompatible with host x86_64-poky-linux-musl (not in COMPATIBLE_HOST)
