Hello Kernel Compiling Error

[smanikandan14]

Hello,

I've been trying to implement the hello world code from the device
drivers chapter of "Beginning Linux Programming". I'm trying to create
module that I can test with the insmod command. I keep getting errors
because I'm compiling using the wrong header:

In file included from /usr/include/linux/module.h:10,
from hellokernel.c:3:
/usr/include/linux/config.h:5:2: #error Incorrectly using glibc headers
for a kernel module

However, I've invoked the compiler as follows:

gcc -D__KERNEL__ -DMODULE -DMODVERSIONS -O2 -Wall -I /usr/src/linux/include -o samplerw.o -c samplerw.c

But, despite my providing what I think should be a directory in which to
search for *.h files (which I believe are the correct ones for my
system, a Fedora Core 3 install) for kernel compilations, I keep getting
the error above based on gcc including the wrong header file


My system details are as below.

# uname -a
Linux wiprosdm 2.6.11-1.1369_FC4 #1 Thu Jun 2 22:55:56 EDT 2005 i686 i686 i386 GNU/Linux


If some body could help that would be appreciable.

Thanks in advance.

Try this makefile, save it in the directory you're working (before the make commands you must have real tabs, not spaces):

obj-m	+= samplerw.o

all:
	make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules

clean:
	make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean

To compile type "make", to cleanup the files type "make clean".
