I want to compile a new kernel 4.14.8-gentoo-r1 on Gentoo Linux. I had created symbolic link using eselect kernel set 2 before I entered to directory /usr/src/linux and I executed genkernel all in this directory. Unfortunately, while compiling Linux kernel 4.14.8-gentoo-r1 I've received following error:

Can anyone help me?

This issue was reported on the Gentoo Forums and the Gentoo bugtracker a little while ago. As mentioned in the bug report, you can either set FIRMWARE_INSTALL=no in your genkernel.conf, or upgrade genkernel to the unstable version (the thread also suggests setting CONFIG_FIRMWARE_IN_KERNEL=y in your .config file, but verify if that's something you want to use.) You probably will want to take note that as of 4.14, Linux no longer has in-kernel firmware, which is why you are getting that error message: genkernel was trying to make something that no longer exists.
