Building linux kernel module/Driver in C code?

I want to compile and run below code I tried lot as

# gcc -C -W -Wall -D__KERNEL__ -DMODULE -isystem /lib/modules/2.6.23.14-115.fc8/build -v /usr/include/linux/version.h -c hello.c

# gcc -C -E -W -Wall -D__KERNEL__ -DMODULE -isystem /lib/modules/2.6.23.14-115.fc8/build -v /usr/include/linux/version.h -c hello.c

# gcc -C -E -W -Wall -D__KERNEL__ -DMODULE -isystem /lib/modules/2.6.23.14-115.fc8/build -v /usr/include/linux/version.h -c hello.c

# gcc -W -Wall -D__KERNEL__ -DMODULE -isystem /lib/modules/2.6.23.14-115.fc8/build -v /usr/include/linux/version.h -c hello.c

# gcc -W -Wall -D__KERNEL__ -DMODULE -isystem /lib/modules/2.6.23.14-115.fc8/build -v /usr/include/linux/version.h -c hello.c

Its not able to find linux/module.h whereas I have installed linux-source code and able to see same file in include/linux/module.h ?


#include <linux/module.h>
int init_module(void)
{
printk("<1>Hello, world\n");
return 0;
}
void cleanup_module(void)
{
printk("<1>Goodbye cruel world\n");
}


I tried by Creating Makefile with contents:

obj-m <tab spaces> := hello.o




===============================then fired below============

# make -C /lib/modules/`uname -r` M=/Project modules
# make -C /lib/modules/`uname -r` M=/Project modules -c hello.c
# make -C /lib/modules/`uname -r` M=/Project modules hello.c
# make -C /lib/modules/`uname -r` M=/Project modules hello.c
