Hello there! Old issue, but with new kernel. Few weeks ago we had similar bug. Please check. Thank You! grep: /lib/modules/4.6.0-gentoo/build/include/linux/version.h: No such file or directory make KBUILD_VERBOSE=1 CONFIG_MODULE_SIG= -C /lib/modules/4.6.0-gentoo/build SUBDIRS=/var/tmp/portage/app-emulation/virtualbox-guest-additions-5.0.20/work/vboxguest SRCROOT=/var/tmp/portage/app-emulation/virtualbox-guest-additions-5.0.20/work/vboxguest modules make[1]: Entering directory '/usr/src/linux-4.6.0-gentoo' test -e include/generated/autoconf.h -a -e include/config/auto.conf || ( \ echo >&2; \ echo >&2 " ERROR: Kernel configuration is invalid."; \ echo >&2 " include/generated/autoconf.h or include/config/auto.conf are missing.";\ echo >&2 " Run 'make oldconfig && make prepare' on kernel src to fix it."; \ echo >&2 ; \ /bin/false) mkdir -p /var/tmp/portage/app-emulation/virtualbox-guest-additions-5.0.20/work/vboxguest/.tmp_versions ; rm -f /var/tmp/portage/app-emulation/virtualbox-guest-additions-5.0.20/work/vboxguest/.tmp_versions/* make -f ./scripts/Makefile.build obj=/var/tmp/portage/app-emulation/virtualbox-guest-additions-5.0.20/work/vboxguest make[2]: *** No rule to make target '/var/tmp/portage/app-emulation/virtualbox-guest-additions-5.0.20/work/vboxguest/VBoxGuest-linux.o', needed by '/var/tmp/portage/app-emulation/virtualbox-guest-additions-5.0.20/work/vboxguest/vboxguest.o'.
