i am using make command for compiling my module , but it is working properly !

see i have created my module ... hello.c & i am taking the help of this article "http://www.cyberciti.biz/tips/compiling-linux-kernel-module.html"

so my whole procedure is based on this article !

This Makefile will work : hello-1.o , hello-1.ko are created ..

Code:

obj-m    := hello-1.o

KDIR    := /lib/modules/$(shell uname -r)/build
PWD    := $(shell pwd)

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

.

I do not think this is the normal way of learning: you have just started to learn "linux" and you now want to implement device drivers without knowing how a simple makefile works. Aren't you?

The way I see it :
A couple of lines are missing in the Makefile's from your link.

Prerequisites for building kernel modules :
A Linux OS that's easy to use for development.
Like Slackware, Fedora 17, CentOS 6.
I.e. the required kernel module build files in /usr/src/
are either included, or easy to install / update.

Which OS do you intend to use ?
