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

what could be the possible cause of this error?

returns the following..

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.
