Hi all,

I was trying to compile a kernel module with kbuild. The module 'test.c' include a header file 'fred.h' and there is a "#include <stdio.h>" in 'fred.h'.

Makefile looks like:

------------------------------------------------------------------------
ifneq ($(KERNELRELEASE),)
obj-m := test.o

else
KDIR := /usr/src/linux
PWD := $(shell pwd)

default:
$(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules


clean:

For 2.6.7 (or 2.6.6) you do not need to specify your own clean: rule.


But upon compiling, there would be errors like this:
In file included from /home/lei/test.c:49:
/home/lei/fred.h:4:19: stdio.h: No such file or directory

The kernel does not provide you with a stdio.h header, so therefore you
cannot find it neither use functionality from it.

You mean I can't use stdio.h at all?

But what if I really need to? Is there anything I can do?
