issue with compiling kernel module

[Arun M Kumar]

I am facing the following error message when i try to compile my kernel 
module.
it is a simple hello world module

make: Entering directory `/usr/src/linux-3.4.6-2.10'

   ERROR: Kernel configuration is invalid.
          include/generated/autoconf.h or include/config/auto.conf are 
missing.
          Run 'make oldconfig && make prepare' on kernel src to fix it.

make: *** No rule to make target `Device'.  Stop.
make: Leaving directory `/usr/src/linux-3.4.6-2.10'



I have tried the said option, of make oldconfig and prepare...

I even recompiled the source using defconfig and am using that kernel, 
but still i get this error.
Please help.
