FYI, pve-common not needed for building the kernel only.
It's the common library for all of our perl code (so all but kernel, qemu, lxc - to name the most popular ones)

FYI, zfsonlinux also has two submodules which may need initializing.

cd /source/pve-kernel/submodules/zfsonlinux && make submodule

also ensure that the correct commit is checked out on all submodules, i.e.,
git status -uno

Does not shows changes (especially on submodules), if so use:

git submodule update --init

to checkout the correct commit.

this is just a symptom of an earlier error, something did not go right earlier.
can you please post your whole build log?
It's probably to big for the mailing list, so maybe use https://gist.github.com/
(or something other, somewhat trustworthy to click on)

this gets generated by the package you want to build, it's just the header files from the kernel...


cheers,
