Dear kernel experts,
I try to compile a module from Linux Device Drivers, 3rd edition:
---
#include <linux/init.h>
#include <linux/module.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);
---
I got a makefile from
http://www.tldp.org/LDP/lkmpg/2.6/html/x181.html
namely
obj-m += helloworld.o
all:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
clean:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean
but that does not work on my system. What makefile should I use and
where should I put my helloworld.c?
Best Wishes
- Gergely
