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.

CC [M] /home/arun/Dev/practice/Kmodules/Hello_world.o
/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,
unimplemented: 64-bit mode not compiled in
make[2]: *** [/home/arun/Dev/practice/Kmodules/Hello_world.o] Error 1
make[1]: *** [_module_/home/arun/Dev/practice/Kmodules] Error 2
make[1]: Leaving directory `/home/arun/Dev/linux-stable'
make: *** [all] Error 2 *//-----------------------------------------------------------------------------------------------------------------*

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

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.
