Unable to build kvm on Debian Buster 4.16.0

[tyxeron]

Hi,

I tried building all three releases on 4.16.0 but it failed.
at sudo make install -j 4 I get the following error:

Error! Bad return status for module build on kernel: 4.14.28+ (x86_64)
Consult /var/lib/dkms/nvidia-current/390.48/build/make.log for more information.

The output of make.log is this:

DKMS make.log for nvidia-current-390.48 for kernel 4.14.28+ (x86_64)
Sun Jul 1 16:35:44 CEST 2018
make[2]: warning: -jN forced in submake: disabling jobserver mode.
Makefile:19: /Kbuild: No such file or directory
make[2]: *** No rule to make target '/Kbuild'. Stop.

I build kvm-sgx by doing
sudo make xconfig
enabling SGX Core and SGX Driver and manually commenting out
CONFIG_SYSTEM_TRUSTED_KEYRING
CONFIG_SYSTEM_BLACKLIST_KEYRING
in .config and then runing

sudo make -j 4&& sudo make INSTALL_MOD_STRIP=1 modules_install -j 4 && sudo make install -j 4

Also I tried before doing anything to copy the config of my kernel by running
cp /boot/config-$(uname -r) .config but that did not change a thing.

Do any of the base kernels, e.g. 4.14.28 without the SGX patches, build with your config?

I will try this and report back later
