I'm fairly sure my kernel sources and configuration are in place:

bolt /usr/src/linux-5.6.14-gentoo # ls -l include/generated/autoconf.h
include/config/auto.conf
-rw--- 1 root root 26144 May 21 10:13 include/config/auto.conf
-rw--- 1 root root 35329 May 21 10:13 include/generated/autoconf.h


Try executing `chmod a+r ` on both of those files.



Yes, thanks, it was a permission issue after all, re-setting umask and 
re-running make mrproper && make && make modules_install fixed it!


All the best,
Jan

That sadly didn't help :-(

Yes, I have a symlink in /usr/src:

bolt ~ # ls -l /usr/src/
total 8
lrwxrwxrwx  1 root root   19 May 21 10:12 linux -> linux-5.6.14-gentoo
drwxr-xr-x 25 root root 4096 May 20 22:03 linux-5.6.13-gentoo
drwxr-xr-x 25 root root 4096 May 21 10:58 linux-5.6.14-gentoo

Is  /usr/src/linux a symlink to  /usr/src/linux-5.6.14-gentoo ? The
nvidia-drivers package looks for the kernel sources in /usr/src/linux so if
the symlink is wrong then you might get errors like these.
