I can compile a basic module using your Makefile. Can you?

[root@localhost:/usr/src/jstuckle]# ls
Makefile  mymodule.c

[root@localhost:/usr/src/jstuckle]# cat Makefile
obj-m = mymodule.o
KVERSION = $(shell uname -r)
     make -C /lib/modules/$(KVERSION)/build M=$(PWD) modules
     make -C /lib/modules/$(KVERSION)/build M=$(PWD) clean

[root@localhost:/usr/src/jstuckle]# cat mymodule.c
#include <linux/module.h>
#include <linux/kernel.h>
int init_module(void)
     printk(KERN_ALERT "Hello world\n");
     return 0;
void cleanup_module(void)
     printk(KERN_ALERT "Goodbye world\n");

Thanks for trying to help.

No, the make fails with a missing Makefile, as indicated in my original post.
