Does not seem to build the modules for 6.15 here, fails at dkms hook phase. In /var/lib/dkms/input-wacom/1.4.0/build/make.log :

@mod20: thanks for finding the solution! I updated the package with a patch for the fix from the git repository, while we wait for a new release.

Devs replied here: https://github.com/linuxwacom/xf86-input-wacom/issues/314#issuecomment-2143108034

TL;DR: This won't build on linux >6.6. There is a fix in the Github repo. I checked it out and sure enough the build does not give any errors.

@mod20: very strange. Are you building directly with makepg or using an AUR helper?

Nope, I've everything there installed. It also seems it's not a recent break because I can trace my first build failure to March 26th. (So this wasn't even building correctly ever since, but I didn't realize it because mkinitcpio apparently just keeps on going if there's a dkms build failure.)

EDIT: Might still be related to the last update of the package since I only installed 1.2.0-1 on that date.

@mod20: that's weird, it's compiling without problems for me. Are you missing anything from the base-devel group?

I am getting compile errors:

I do have libbsd installed.

Not sure if the PKGBUILD needs a minor adjustment or if everything is correct.

@Roq: does it work now with arch set to 'any'?
