Re: Simple module, but won't build

When I #include <asm/io.h> I get this error:

I know I have used these with no problems with an older kernel and
compiler. Is there something I need to add to make these work??

Seems you are missing to include some necessary header  files  and/or
to provide the necessary compiler options.

It's difficult to guess what  exactly  is  missing  given  so  little
information.
