Can't get nvidia-dkms-open to compile

Question

Closed this issue 3 months ago · 8 comments

I've confirmed that I'm installing the latest nvidia-dkms-open with CachyOS patches, which does have this patch, but I keep getting the error:

ERROR: modpost: "drm_fbdev_ttm_setup" [/var/lib/dkms/nvidia/560.35.03/build/kernel-open/nvidia-drm.ko] undefined!

How is this possible? Is this something due to erroneous configuration of my built Linux kernel?

Mhm, thats weird. Which kernel version youre running?

Im using nvidia-open-dkms from our repository and its working fine.

I'm running 6.11.2. Tried clearing my ccache and still the same happens

Can you try with a non modprobe kernel?

Answer 4 · 2024-10-05T16:04:01.000Z

It compiles with other kernel headers (e.g., stock arch kernel) without trouble

It compiles with other kernel headers (e.g., stock arch kernel) without trouble

Then I would suspect the stripped config, no?

Just built the latest one from the CachyOS-PKGBUILDs (since its not in repo yet) but it worked fine:

Cleared ccache, recompiled my kernel, now everything's working. Really weird, must be some strange ccache bug or config bug.
