Hi, Currently, kbuild makes -I option expansion without any check if the resulting include directory exists. It produce warnings if you try to build with W=1 which enables -Wmissing-include-dirs. For example: $ make W=1 O=~/var/tmp drivers/gpu/drm/drm_auth.o Using /home/space/kas/git/public/linux as source for kernel GEN /home/space/kas/var/tmp1/Makefile CHK include/linux/version.h CHK include/generated/utsrelease.h CALL /home/space/kas/git/public/linux/scripts/checksyscalls.sh CC [M] drivers/gpu/drm/drm_auth.o cc1: warning: include/drm: No such file or directory [enabled by default] It would be nice to address the issue. P.S. [enabled by default] is gcc bug. [-Wmissing-include-dirs] should be there. http://gcc.gnu.org/bugzilla/show_bug.cgi?id=51303 -- Kirill A.
