Makefile to compile kernel modules

[Amit Nagal]

Hi ,

i want to compile a standalone kernel module for  linux kernel
version 2.6 or 3.0 .

A basic Makefile goes like this :

==================
obj-m += hello-1.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

====================


i want to add debugging symbols information ( using -g option ) also
via CFLAGS  usage flag .

can i be guided how to modify this basic Makefile to add CFLAGS information for
adding debugging symbols information .
