Not a duplicate of bug 434503. I had bug 434503 before, and after using the workaround described there, I now get this bug.
Notice the different exit status of 10 vs exit status 3 on bug 434503.

Could you please post the file /var/lib/dkms/vboxdrv/3.0.6/build/make.log

[Felix Geyer (debfx)]

If make.log isn't there, please search for it somewhere in /var/lib/dkms/vboxdrv/3.0.6

 don't have folder /dkms/...

[Kai Blin (kai.blin)]

Here's my make.log file.

[Felix Geyer (debfx)]

Seems to be caused by bug #438393

[Kai Blin (kai.blin)]

I don't have an env-var set.
However, /usr/local/bin/gcc is a link to /usr/bin/ccache

[Kai Blin (kai.blin)]

Anyway, removing the symlinks fixes the issue, so at least that's a viable workaround.

Assigning to dkms.

I've had three systems now affected by this bug, when building nvidia-190 kernel modules. Same issue with nvidia-185 as well, this seems highly related to bug 438393 as noted above, but since it does not involve the environment variables I'm posting here.

The build fails with the same make.log as 438393 "The C compiler '/usr/local/bin/cc' does not appear to be able to create executables", in this case a link to ccache. The referenced bug also mentions that dkms tries to run as user nobody, running as nobody ccache tries to create a cache at "/nonexistent/.ccache" which of course fails. Hope this is helpful.

So the fix to this is the same as the fix to bug 484725, which will be fixed in the next Lucid upload.
