[pkg-nvidia-devel] Bug#582748: nvidia-kernel-dkms: fails to build module due to missing files

[Alexander Heinlein]

Hi Andreas,

good news, I found the reason: ccache
So far I don't know why it breaks the installation process. The source
compiles nevertheless, some of the created object files just have the wrong
name. Interestingly, this does not happen on any other source code here.
Also, I have ccache running for a very long time and haven't had problems in
the past, even with the nvidia installer. Maybe you spot the reason in the
given information below, otherwise maybe ccache should be disabled by
setting CCACHE_DISABLE=1 before compiling the source.

I guess you mean /usr/src/modules/nvidia-kernel

ls -la /usr/src/modules/nvidia-kernel
