Building nvidia driver with dkms fails on debian jessie/sid 3.14-rc8 (git)

Hello everyone, Not sure if I should send this here since this deals with a proprietary driver but i'll give it a try. I'm trying to build the nvidia driver with: $ sudo dkms build -m nvidia-current -v 331.49 -k 3.14.0-rc8-00011-gf217c44 it fails with output: Building module: cleaning build area.... env CCACHE_DISABLE=1 make -C .SYSSRC=/lib/modules/3.14.0-rc8-00011-gf217c44/build....(bad exit status:2) Error! Bad return status for module build on kernel: 3.14.0-rc8-00011-gf217c44 (x86_64) Consult /var/lib/dkms/nvidia-current/331.49/build/make.log for more information. make.log (attached) tells me the kernel config is invalid and to make oldconfig && make prepare I do so but I still get the same error. Any ideas? Thanks, Tyrell
