Compiling problem on SLES 15 SP3 #266

Closed Martin-Weiss closed 1 year ago

Martin-Weiss commented 2 years ago

For some reason I can not compile and get this error:

As I am not a developer I am seeking for some help, here..

Any ideas?

Feedback on my own -> had to remove the backport v5.5_vb2_kmap.patch and then the compile worked!

look like not-LTS kernel with forced patches from 5.4+

Yeah - the kernel has back-ported patches. Do you know if there is a way to detect if patches in backports are required during build and auto-select them?

Updated, now compatible with 4.14 - 6.2
