Unable to build against headers on 5.10, 5.11

[coledeck]

Hi, I'm having trouble building DKMS modules on 5.10+ with this.

On 5.9.16 and the PVE 5.4 kernel they build totally fine.

Looking on a web search, people had this issue with 5.10rc4 but it was fixed in 5.10rc7 so I'm not sure it's related. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=975571

On 5.10.16 and 5.11.0, both modules I tested have the following error:

make[3]: *** No rule to make target 'scripts/module.lds', needed by '/var/lib/dkms/zenpower/0.1.12/build/zenpower.ko'. Stop.

Full DKMS log for another module:

root@main-server ~/linux> dkms install vendor-reset/0.1.1 -k 5.10.16-1/x86_64 --force --verbose

Kernel preparation unnecessary for this kernel.  Skipping...

Faced this as well, ubuntu packaging issue, workaround: https://github.com/Mange/rtl8192eu-linux-driver/issues/205#issuecomment-736366347

Hi,

Thank you for reporting this issue. I have added a workaround for this issue in the latest build. Could verify whether it works for you?

You can download the builds from here.

[coledeck]

Yep, it appears to build fine. If you could update the releases version of 5.11, maybe like 5.11.0-2 or something that would be great.

[fabianishere]

Will do!
