Have you tried installing libudev or udev from your system package manager? I do agree that this error message could be nicer.

Once you've worked out how to do so (for all the required dependencies), documenting it here would be welcome, and we can add it to https://github.com/bevyengine/bevy/blob/main/docs/linux_dependencies.md

[LeSnake04]

Looks like there is no udev on Artix, they use system/eudev and system/libeudev instead.

[LeSnake04]

But i dont think its worth making workarounds, since gentoo stopped maintaining eudev and is switching back to udev, so its very likely artix will go to udev too.

[bjorn3]

Seems like it will continue to be maintained after all:

eudev-project/eudev@4aeeabe and eudev-project/eudev@1d093c2

ADOPTION NOTICE (2021-09-14)

Currently eudev is in the process of being adopted by a newly formed project by Alpine, Devuan and Gentoo contributors (a-z order). Some of the below links and/or contacts may be outdated until the process is complete and all the infra set up.
