Your linux-stable is build right? If not try to build it first then compile your module.

This is your running /installed kernel not the one you are building it against.

Based on the error messages, I'd say you're trying to compile in 64-bit mode
with a compiler build to support only 32-bit, or similar.

Kernel Module Compilation error

[Arun M Kumar]

Hi,

     I get the following error while compiling my very basic kernel 
Module (a hello world module)

*
//--------------------------------------------------------------------------------------------------------------*
make -C /home/arun/Dev/linux-stable M=/home/arun/Dev/practice/Kmodules 
modules
make[1]: Entering directory `/home/arun/Dev/linux-stable'

   WARNING: Symbol version dump /home/arun/Dev/linux-stable/Module.symvers
            is missing; modules will have no dependencies and modversions.

/home/arun/Dev/practice/Kmodules/Hello_world.c:1:0: error: code model 
'kernel' not supported in the 32 bit mode
/home/arun/Dev/practice/Kmodules/Hello_world.c:1:0: sorry,

what could be the possible cause of this error?

on my system

*$uname -a*

returns the following..

*Linux linux-xh55.site 3.4.6-2.10-desktop #1 SMP PREEMPT Thu Jul 26
