Hi all,
I am new to Linux. I am tring to load a module in kernel of 'Fedora core2'.
I wrote a simple Hello world program and tring to compile it with Makefile. I tried 3 differnt types of make file but still it is giving me error. I will really appritiate any help.
Here is my Hello world program:
#include <linux/init.h>
#include <linux/module.h>
#include <linux/kernel.h>
static int hello_init(void)
{
printk(KERN_ALERT "Hello, world\n");
return 0;
}
static void hello_exit(void)
{
printk(KERN_ALERT "Goodbye, cruel world\n");
}
module_init(hello_init);
module_exit(hello_exit);
Here is the Makefile:
ifneq ($(KERNELRELEASE),)
obj-m:= hello.o
else
KDIR:= /lib/modules/$(shell uname -r)/build
PWD:= $(shell pwd)
default:
$(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules
endif
Problem here is once I type the command "make" at the shell prompt it gives the following message :
$ make: Nothing to be done for 'default'

[SNIPPED..]
Dear future Linux Hacker.
Try this for your Makefile. It works fine.
KDIR := /lib/modules/$(shell uname -r)/build
PWD := $(shell pwd)
obj-m := hello.o
default:
$(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules
Cheers,
