Unhappy Trying to Compile "hello world" Kernel Module (please help!)

Hello,

I am trying to compile an example from the Oreilly Press book "Linux Device Drivers". Here is the example code:

Code:
#include <linux/init.h>
#include <linux/module.h>
#include <linux/kernel.h>	

MODULE_LICENSE("Dual BSD/GPL");

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);
The problem is that when i try to compile with this: gcc -c -I /usr/src/linux-2.6.16/include/ hello.c , I get all of this:

Code:

No, put the hello.c in your home dir or somewhere, not in the true kernel source. If its in your homedir, cd into the home dir and do this:

make -C /usr/src/linux-2.6.16/ M=`pwd` modules

Hey, thanks for the reply. THe command that you posted is used to make the actual module from the object file, am I correct? My problem is that I cant make the object file itself using my program and the kernel source. The command that I used above was run on hello.c in my home directory as well as the kernel directory and both dont work. How is it that I compile my hello.c into an object file without such errors?

.....My apologies. Um, yes that worked quite well. What exactly does that command do, and how does it know what c file to compile? Oh and THANKS!

Oh, yea, and I understand that its using the make command and the appropriate Makefile. But I dont understand how this make syntax works.

Its using the make file in the kernel source directory. Since your file is ".c," and you did "make modules," all the .c files that are supplied in the "M=" directory, for which you supplsed `pwd1, are treated as modules. There is a discussion in that book about this in the section called "Compiling and Loading Modules" or something like that.

Glad to help.

Hi,
I am using ubuntu-9.04 and have compiled kernel 2.6.28.10.
I tried to compile my "hello-world" module using the above command
I am still getting the following errors.

Code:
"make -C /usr/src/linux" M=`pwd`

this worked for me

Makefile
Code:
obj-m = hello.o
KVERSION = $(shell uname -r)
all:
        make -C /lib/modules/$(KVERSION)/build M=$(PWD) modules
clean:
        make -C /lib/modules/$(KVERSION)/build M=$(PWD) clean
hello.c
Code:
#include <linux/module.h>       /* Needed by all modules */
#include <linux/kernel.h>       /* Needed for KERN_INFO */
#include <linux/init.h>         /* Needed for the macros */

static int __init hello_start(void)
{
printk(KERN_INFO "Loading hello module...\n");
printk(KERN_INFO "Hello world\n");
return 0;
}

static void __exit hello_end(void)
{
printk(KERN_INFO "Goodbye Mr.\n");
}

module_init(hello_start);
module_exit(hello_end);
