[linux-dvb] Re: <was blank> Building problems

[Peter Henderson <peter.henderson@starjar.com>]

I think my original instructions were incorrect.

tar xjf linux-2.6.7.tar.bz2
patch -p1 <patch-2.6.7-krazel
makelinks


Basically swap makelinks and patching the kernel, which seems to fix all 
the problems with make xconfig.
(I just ran into this myself, setting up another pc with a Avermedia 
card, in order to see if my IRQ problem is hardware based.)
