Could you please help to resolve compilation issue. Thank you!

I have absolutely the same issue.

[mripard]

You've very likely not installed the headers of our kernel, which are adding those definitions.

[Dreyk007]

Same problem for me. But i have linux-cedrus headers installed. How else can I fix this error?

[maximst]

Yes, I am have linux-cedrus headers installed to. But get the same error.

[adriancable]

Same problem for me - and I do have the headers installed. Did we ever find a resolution for this?

This repository hasn't been updated for the latest kernel sources. I'm using on of pH5's branches: https://github.com/pH5/libva-v4l2-request/tree/multi-context

Tried both pH5 and bootlin, but the problem stays the same:

You've very likely not installed the headers of our kernel, which are adding those definitions.

I am using odroid's ubuntu kernel (linux-image-xu3 aka linux-image-4.14.111-139) for which there is no ready kernel header ubuntu package, so I cloned the headers using git:
git clone --depth 1 https://github.com/hardkernel/linux -b odroidxu4-4.14.y
and created links

ln -s /root/linux /lib/modules/$(uname -r)/build/include/linux
ln -s /root/linux /usr/src/linux-headers-$(uname -r)/include/linux

Still getting the same error.
