I started reading Orielly Developing Device Drivers and tried following program
#include <linux/init.h>
#include <linux/module.h>
MODULE_LICENSE("Dual BSD/GPL");
static int hello_init(void)
{
printk(KERN_ALERT "Hello,world tapas\n");
return 0;
}
static void hello_exit(void)
{
printk(KERN_ALERT "Good Bye,cruel world\n");
}
module_init(hello_init);
module_exit(hello_exit);

I wrote above program in /home/tapas directory with name hello.c
First I tried to compile as
make hello.c
it gave error
as suggested in book on page 17 of chapter two
% make
make[1]:
I tried as
make hello.c
got following error
make: Nothing to be done for `hello.c'.
and tried just make
make
make: *** No targets specified and no makefile found. Stop.
I am wondering as how do I compile my first kernel module.
So what did I miss?
