I'm getting a strange build error when I try to build documentation in the Zephyr master branch. Has anyone ever seen this before? This is an up-to-date Fedora 25 machine.
apboie@apboie-mobl1:/projects/zephyr/doc master /projects/zephyr
$ make htmldocs
srctree=../ SRCARCH=x86 python scripts/genrest/genrest.py ../Kconfig reference/kconfig/
../Kconfig.zephyr:11: warning: The symbol KERNELVERSION references the non-existent environment variable KERNELVERSION and will get the empty string as its value. If you're using Kconfiglib via 'make (i)scriptconfig',
it should have set up the environment correctly for you. If you still got this message, that might be an error, and you should email ulfalizer a.t Google's email service.
