> Hi all,
> this is probably a simple question but I am not sure where to look for
> the answer.  I have Rubini's Linux Device Drivers book, and I am trying
> to get his example Hello World module going.  I am running Red Hat 6.2
> kernel 2.2.14-5.0.  Here is the code that I use:
> 
> #define MODULE
> #include <linux/module.h>
> 
> int init_module(void) { printk("<1>Hello World\n"); return 0;}
> void cleanup_module(void) {printk("<1>Goodbye\n");}
> 
> and this is what I type when I am logged in as root:
> 
> # gcc -c hello.c
> # insmod hello.o
> 
> the message "Hello World" does not get displayed
> 
> then I type:
> 
> #rmmod hello
> 
> the message "Goodbye" does not get displayed.
> 
> I can tell (I think) that the module is being inserted because if I try to
> 
> insert it twice without removing it first, it says a module with that name
> 
> already exists.

> Any ideas?
