Hello, I'm sorry, but with updating on Kernel 5.8.2 I encounter some real problems: Together with the kernel also gcc and gcc-libs were updated from 10.1.0-2 to 10.2.0-1, I don't know if this is important....

Messages from pacman.log:

==> dkms install --no-depmod -m nvidia -v 340.108 -k 5.8.2-arch1-1 Error! Bad return status for module build on kernel: 5.8.2-arch1-1 (x86_64) Consult /var/lib/dkms/nvidia/340.108/build/make.log for more information. ==> Warning, `dkms install --no-depmod -m nvidia -v 340.108 -k 5.8.2-arch1-1´ returned 10 ==> depmod 5.8.2-arch1-1

[....]

I tried to reinstall nvidia but:

==> Unable to remove module nvidia/340.108 for kernel 5.8.2-arch1-1: Not found in dkms status output.

In make.log gcc-version-check failed. (I mentioned gcc was upgraded):

DKMS make.log for nvidia-340.108 for kernel 5.8.2-arch1-1 (x86_64)

gcc-version-check failed:

The compiler used to compile the kernel (gcc 10.1) does not exactly match the current compiler (gcc 10.2). 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.

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.

Failed CC version check. Bailing out!

Well, I'm badly surprised, because all formerly updates worked without any problems. Patch 5.7 worked really well and also upgrading to 5.8.1 was without any errors. I use an over ten years old machine (core2duo) with Nvidia gt210 and running xfce4 on it.

Please, can anyone help with this? Best regards!

You can try installing flatpak or snapd.

They have the latest version of Spotify:

@fvsc - Thanks for testing. Now that 5.8.1 has moved to [core] I pushed this formally a few min ago.

For me is the combination PKGBUILD and PATCH working with kernel linux 5.8.1.arch1-1. NVIDIA Corporation G98 [GeForce 8400 GS Rev. 2] (rev a1) Thanks.

@papakilo - It seems they have a patch for 5.8. Does anyone know how the navigate launchpad? I need to find their source patches to see how to adapt to our package.

Towards the end:

-rw-r--r-- root/root      2373 2020-08-08 12:55 ./usr/src/nvidia-340-340.108/patches/buildfix_kernel_5.8.patch

EDIT: I got it, needed to look at the "available diffs" for example: https://launchpad.net/~kelebek333/+archive/ubuntu/nvidia-legacy/+files/nvidia-graphics-drivers-340_340.108-1lmtrfocal3_340.108-2lmtrfocal.diff.gz

I now have a package that builds against 5.8. Can someone with supported hardware try it? I don't want to push to AUR until linux-5.8 goes into [core]:

• PKGBUILD: https://gist.github.com/graysky2/25422e5160ea8d92da5977674c541c39
• patch: https://gist.github.com/graysky2/a07851c3f835dc748079bfec0aee636a

Just for info, Ubuntu and derivatives have Nvidia 340 drivers for kernel 5.8 here: https://launchpad.net/~kelebek333/+archive/ubuntu/nvidia-legacy

@papakilo - They aren't ... I cannot build this package against 5.8.0

@graysky - Hi, patches for kernel 5.7 have been around and worked good for some time, as I'm using kernel 5.7.14 and Nvidia 340.108 in Manjaro. So I suppose those patches could be the same for kernel 5.8...

@papakilo - Thank you for the link, but unless the new patche(s) are also backwards compatible with 5.7 which is currently offered in [core], and until the 5.8 kernel package moves from [testing] to [core], the package is not out-of-date.

Also, the link you posted only shows a 1-month-old patch for 5.7. I did not see a modification for 5.8. Perhaps I missed it?
