Am I obliged to compile the kernel to compile a module?

[abdelkader belahcene]

Hi,
I write  a module.c  and want to add to the kernel.

I downloaded the corresponding source ( linux-3.0.tar.bz2), and put it in
in /usr/src/linux-3.0
in the makefile for my modle I tried

     make -C   /usr/src/linux-3.0 M=$(PWD) modules

It failed , it looked for  something like /lib/modules/3.0/build

 How to create this directory (build) ?

Am I obliged to compile the kernel ?

thanks for help
