Failed to run custom build command for `libudev-sys v0.1.4`

I was trying to install supergfxctl and I was following this tutorial Files · main · asus-linux / supergfxctl · GitLab but when I got to the point of installing supergtxctl “cd supergfxctl
make && sudo make install” I ran into this issue:

error: failed to run custom build command for `libudev-sys v0.1.4`

Caused by:
  process didn't exit successfully: `/home/boni/supergfxctl/target/release/build/libudev-sys-2e49a35aecd1e32f/build-script-build` (exit status: 101)

I’ve tried to search for an answer but nothing seems to solve this issue so I’d really appriciate some help.

You want the systemd-devel package on Fedora - the libudev-dev name is for Debian/Ubuntu systems.

Given what it really wants is pkg-config support for libudev you could also find it by installing the pkgconfig(libudev) virtual package like this:

sudo dnf install 'pkgconfig(libudev)'

It works! Thank you very much, sorry for the late reply I was busy today.

Hi there, thank you so much ! I had the same issue and couldn’t find any solution for fedora!
