Can any one tell me what should i do to make my user

Kernel compilation is very different from a user-space
programming in a GNU/Linux environment.
In kernel-space you have special gcc flags and you are
using the kernel header files.
In user-space programming, you will be using glibc,
mostly.
Can i have common makefile for 2.4 and 2.6 driver
module.
Well, you could. You have the freedom to. But, its
convenient to maintain separate Makefiles considering
all the rules you can have.
At present i am using 2 differnt makefiles and
changing them when ever i
cahnge the kernel.
No harm in it.
