Nvidia dkms module and kernel 6.8.9: gcc version mismatch

updating my system DKMS hooks fail because:  The compiler used to compile the kernel was gcc 13.2; the current compiler is gcc 14.1.

gcc-version-check failed:

You appear to be compiling the NVIDIA kernel module
with a different compiler than the one that was
used to compile the running kernel.  The Linux 2.6
kernel module loader rejects kernel modules built
with a version of gcc that does not exactly match
that of the compiler used to build the running
kernel.  The compiler used to compile the kernel
was gcc 13.2; the current compiler is gcc 14.1.

If you know what you are doing and want to override
the gcc version check, you can do so by setting the
IGNORE_CC_MISMATCH environment variable to "1".

In any other case, set the CC environment variable
to the name of the compiler that was used to compile
the kernel.

yah,  gcc should be updated on the build server before the kernels are built.. at least when there's a major version bump..
if it's any consolation, arch have done the same: https://aur.archlinux.org/pkgbase/nvidia-470xx-utils?
short term solution is to downgrade gcc and gcc-libs and reinstall nvidia-*-xxx-dkms

ok, but shouldn't that chroot have had it's gcc updated before the kernels were built?
presumably, it's just that kernel updates went through before the gcc one..
i mean, i get that it's not a huge priority, it only affects a couple of nvidia dkms packages..

EDIT: ah, looks like these nvidia drivers might need patching for gcc 14 anyways

for the moment I downgrade linux, linux-headers, gcc, gcc-libs, and put them to IgnorePkg in pacman.conf

the 340 AUR build, which i presume you're using, has now been updated with a patch for gcc 14
there's also GCC-14 patches for 470 and 390 in their AUR comments, if artix packagers see this.
i can confirm the 470 patch works for me.

Because the maintainer of AUR has already added the GCC 14 patch. If you still have 13.2.1 version then what exactly are you surprised at?

Still there is a GCC version mismatch. Nvidia-340xx-dkms driver build successfully with gcc 14.1 , but the linux kernel on artix repo is built with gcc 13.2. DKMS:

No its not.

Code: [Select]
installed = gcc-14.1.1+r1+g43b730b9134a-1-x86_64
installed = gcc-libs-14.1.1+r1+g43b730b9134a-1-x86_64

If you happen to have any kernel module from arch repos, thats your problem, since arch have a borked pkgver for the current gcc version.

Code: [Select]
artix: gcc-14.1.1+r1+g43b730b9134a-1      
arch: gcc-14.1.1+r1+g43b730b9134-1
                   


Our build system is way less error tolerant than arch build system.
