Hi. Am unable to compile nvidia drivers on latest fedora 22 kernel. Anyone else having similar issues? At any rate I guess I would like to report this problem.

The kernel version is 4.0.0-0.rc5.git4.1.fc22.x86_64 and I have the kernel-devel packages installed.

There is no /usr/bin/nvidia-bug-report.sh because it never finishes the install.

from the end of /var/log/nvidia-installer.log

 if [ "-pg" = "-pg" ]; then if [ /tmp/NVIDIA-Linux-x86_64-346.47/kernel/os-registry.o != "scripts/mod/empty.o" ]; then ./scripts/recordmcount  "/tmp/NVIDIA-Linux-x86_64-346.47/kernel/os-registry.o"; fi; fi;
 if [ "-pg" = "-pg" ]; then if [ /tmp/NVIDIA-Linux-x86_64-346.47/kernel/os-interface.o != "scripts/mod/empty.o" ]; then ./scripts/recordmcount  "/tmp/NVIDIA-Linux-x86_64-346.47/kernel/os-interface.o"; fi; fi;

Thanks for any ideas anyone has. This is for the “bumblebee-nvidia” rpm package some fedora users (myself included) are using for optimus support on fedora. But I think it will also affect desktops.

346.47 does not support kernel 4.0-rc.
You need a patch for that

Thanks so much. It worked.
