Arch Linux User Repository

An update in applesmc-next's main branch was pushed 2 weeks ago to fix the Linux 6.15 build issue. However, it does not have a tagged version to base the build. PKGBUILD may need an update so that it pulls from the main branch.

Ref: https://github.com/c---/applesmc-next/commit/c125e50911053a0595fe56f48da3874587c59d46

@rahulmb What I did was 'sudo cp /usr/src/applesmc-next-0.1.5/sbs/acpi/sbs.h /usr/lib/modules/6.15.2-arch1-1/build/include/acpi/' and then reinstalling kernel and headers. That seems to do the trick.

In case this helps, this is the output of /var/lib/dkms/applesmc-next/0.1.5/build/make.log

Thank you! It's been working really well. The kernel's applesmc module hasn't seemed to work for me, but your's has been working without any issues until this build issue

@rahulmb The acpi/sbs.h file is included as part of the package. Maybe something changed in the kernel build system. I have not been able to keep this package up to date because I don't have access to a Mac any more. I should be able to test this problem though. I'll see if I can figure out why it won't compile.

I just updated to kernel 6.15.0

Running into this issue:

applesmc/applesmc.c:43:10: fatal error: 'acpi/sbs.h' file not found

@Szadek Thanks for reporting back. I was having a hard time generating the original error again so I wasn't sure if it was fixed or not.

@ozz hi , the commit 3f500c4 fixed the issue for me.

Thank you, best regards

@Szadek It's safe to force it. I'll try to figure out what is going on and fix it.
