How familiar are you with C? One important thing to remember, and the
thing that's bitten you, is that the language allows you to
"prototype" functions in header files. Essentially, these promise that
somewhere in the sourse, the functions that are mentioned actually
exist and "this is how to call them" They also contain definitions of
structures used within the code, as well as macros.

What's this got to do with your problem? Your ALSA drivers need to
know how the kernel fits together when you compile them. Thus they
need the kernel header files, and therefore you need the source at
least.

Does that help?

Cheers,

Simon
