Hi all,
I have redhat-7.2 on X86.
I have written a simple sample driver.
*******
Code is as below:
#define MODULE
#include<linux/kernel.h>
#include<linux/module.h>
int init_module(void)
{
printk("Module inserted\n");
return 0;
}
void cleanup_module()
{
printk("module removed\n");
}
*********
I compiled it with
gcc -c -Wall -DMODULE -D__KERNEL__ driver.c
Inserted module with:
insmod driver.c
But printk statements are not giving any output
even after "rmmod driver" I get no output.
But if I do "cat /var/log/messages"
output can be seen in "messages" file.
Can anybody help me with this.
Thanks for any help in advance.
Manoj
