Has anyone had success compiling this under kernel 6.7.0-arch3-1? Is that an issue from the Arch kernel or does this look like a general incompatibility with 6.7.0?

@andrfgs I got it to build in a clean chroot by adding linux-headers to the depends array as I am not running the LTS kernel. Looking at https://wiki.archlinux.org/index.php/DKMS_package_guidelines it does not seem like the header file should be a required dependency.

The package is broken, even with linux-lts-headers installed:

make -C /usr/lib/modules/5.8.6-arch1-1/build M=/home/user/.cache/yay/akvcam-dkms/src/akvcam-1.1.0/src  modules
make[1]: *** /usr/lib/modules/5.8.6-arch1-1/build: File or folder doesn't exist.  Stop.
make: *** [Makefile:42: all] Error 2

Works with linux-lts-headers now! Thanks!

I've removed the linux-headers dependency because linux-headers-lts does not provides it. It may work now.

Please add linux-lts as a dependency :)

This doesn't compile

For anyone having trouble compiling on 5.7 kernels, this patch fixes it:
