Please send dkms' make.log, probably located at /var/lib/dkms/nvidia-current/418.113/4.19.0-9-amd64/x86_64/log/make.log Please try the modules I built in a clean buster environment from nvidia-kernel-source for the latest buster kernel: install https://people.debian.org/~anbe/418.113/nvidia-kernel-4.19.0-9-amd64_418.113-1+4.19.118-2_amd64.deb and remove nvidia-kernel-dkms (to remove the broken build; this will remove make.log, too, so save it first) If that works, something is broken in your environment w.r.t building modules, but I'm not sure how to diagnose ... your gcc-10 experiments could be related. What do these commands say? gcc-8 --version ld --version Andreas
