Just upgraded and can't build dkms

@andrewfader Maybe the issue isn't in any way DKMS related? Maybe LKRG somehow fails to build for you in general? Please take a look at (apparently) /var/lib/dkms/lkrg/r481.7bb9cf1/build/make.log or/and try to build LKRG manually.

solardiz commented 1 year ago

Oh, it literally says you're missing headers for your kernel version! So just install those.

andrewfader commented 1 year ago

I do have the correct headers installed @solardiz , any other suggestions on how I can get a log of how this doesn't build? It's been building fine until now.

Nevermind I figured it out ... somehow I had a /usr/lib/modules/5.18.12-hardened1-1-hardened/ and a /usr/lib/modules/5.18.12-hardened1-2-hardened/

andrewfader commented 1 year ago

No I thought i fixed it but it's still busted even with the standard linux kernel...

andrewfader commented 1 year ago

Nvm, it's a problem with the arch pkg, needs to change dkms.conf from p_lkrg to lkrg

solardiz commented 1 year ago

@andrewfader Thank you for posting these updates. I see you've also posted a comment to https://aur.archlinux.org/packages/lkrg-dkms - great! I hope this will be taken care of in Arch's update to 0.9.4.

andrewfader commented 1 year ago

and https://aur.archlinux.org/packages/lkrg-dkms-git as well. Thanks for checking back in. Hopefully the arch package maintainer will check it out within a few days.
