Kernel modules programming environment

[series]

I'm looking into writing some simple device drivers, just to get a deeper understanding.

However, I need a built kernel tree to compile against... So far so good. But how do I actually "install" this kernel tree? I assume it should be put in /usr/include/ ? Could I just copy it there, overwriting whatever is there already?

It of course doesn't work to use absolute paths in the source files that points to my current kernel tree

Thanks.

Nevermind, I found the relevant documentation.

I always post to fast!
