I've also been searching for the answer to this question.

What I'd like to be able to do is set a couple of extra 'include' paths. (I note from earlier articles that setting 'CFLAGS' is .. umm.. discouraged.)

I hope there's a work around, otherwise it makes it difficult to develop modules outside the kernel tree that depend on each other.

Does there exist a solution?

Thanks,

Geoff

I needed to do the same thing. You can do this with the EXTRA_CFLAGS Makefile variable:

...
obj-m += file.o
EXTRA_CFLAGS += -I$(obj)/../include
