kernek version problem

i have written a small module :



#define MODULE
#include
int init_module(){printk("<1>hello world");return 0;}
void cleanup_module(void){printk"<1>bye world");}

it got compiled without errors.when i'm trying to run
it by insmod:
insmod ./hello.o

i got the error message as:
../hello.o :kernel module version mismatch
../hello.o was compiled for kernel version 2.4.20 while
this kernel is version 2.4.21-4.EL

how do i update my kernel?
is there any way to bypass the kernel version
dependencies?

Yes there is a way (modprobe --force your_module).

What linux distribution do you use? There is different ways to install
kernel sources...

Re: kernel version problem

i've tried both the methods:

1.modprobe --force ./hello.o
2.-I in gcc (/usr/src/linux/include)

i'm getting "kernel will get tainted" warnings.

anyother better way?
In my /usr/src/ I have two folders one as LINUX and
also LINUX2.4.21-4.EL
how is it possible?
moreover, the LINUX folder has an arrow symbol over
it?what does that mean?

Re: kernel version problem

Hi Rekha,
When i said use -l /usr/src/linux/include it does not mean u
have to type "exactly" that, the name of the folder will be different.
Use that name. Besides the arrow thing you are talking about is
actually a soft link (asuming you saw it in ls listing).

Bye
