at the 'make bzImage' step, i see that ^

what is that? (apart from a mess) any ideas are appreciated.

I am getting those errors too, or atleast was at one time. I got so frustrated with what patches and diff's had been applied and everything that I'm starting over with a fresh kernel source tree, and the latest things off the v4l / bttv site.

Will post reply if it works.


Side note: Isn't it frustrating how poorly documented this linux tv stuff is??? The only docs out there are from roughly 2001, before the 2.4 kernel!

i figured it out by now btw.

What was wrong?
