I am using redhat 9.

I copiled a module "test.o". When tried to insert it by calling

"insmod test.o"

it is complaining. Below is the error message:

test.o: kerner-module version mismatch
test.o was compiled for kerner version 2.4.20
while this kerner is version 2.4.20-8.



Could anyone help me with this issue and guide me so that I can test these module.

Tahnks.

you can force the module to load with the -f option

I tried it. I did not get expected result. When I ran "insmod" I expected to see "Hello, World" and when I ran "rmmod" I expected to see "Goodbye cruel world". I did not see these messages. Could you please tell me whats happening there.


Below is my program:
==================
#define MODULE
#include <linux/module.h>

int init_module(void) {printk("<1>Hello, World\n"); return 0; }
void cleanup_module(void) {printk ("<1>Goodbye cruel world\n"); }



Below is what I tried:

[root@localhost devicedrivers]# ls
