company-clang doesn't work with kernel 5.3.6

[choyoungcin]

Hi tuhdo,
I follow your blog and want to build an ide environment for kernel code reading.
When I try complete-mode with clang, something seems go wrong.
For example, when i type in

struct devi

then type command M-x company-complete, I wish struct device be auto-completed or a completion menu popped up, but i get the hint No completion found in the echo erea.

I got the following errors from clang-error buffer:

clang failed with error 1:
/usr/bin/clang -fsyntax-only -Xclang -code-completion-macros -x c -I/home/gnu/linux-5.3.6/include/ -I/home/gnu/linux-5.3.6/arch/arm/include/ -Xclang -code-completion-at=-:95:26 -

Below is the content of variable company-clang-arguments

Its value is
("-I/home/gnu/linux-5.3.6/include/" "-I/home/gnu/linux-5.3.6/arch/arm/include/")
Original value was nil
Local in buffer Makefile; global value is nil

This variable’s value is directory-local, set by the file
‘/home/gnu/linux-5.3.6/.dir-locals.el’.

Documentation:
Additional arguments to pass to clang when completing.
Prefix files (-include ...) can be selected with ‘company-clang-set-prefix’

You can customize this variable.

Any suggestion or help?
Many thanks
