Compiling modules in kernel 2.6.7

[Alejandro Sánchez Acosta <asanchez@xxxxxxxxxxxxxxxx>]

Hello,

I have updated to linux 2.6.7 and have tried a module but now it is not
working. 

Here it happens the same with a sample hello world kernel module.

#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);

And 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

And the errors are:
make -C /lib/modules/2.6.7/build/ SUBDIRS=/home/alejandro/work/modulo
modules
make[1]: Entering directory `/usr/src/linux-2.6.7'

Any clue?

Thanks in advance,
