[linux-dvb] Re: video4linux and dvb-kernel conflicts

[Sebastian Rohde <sebastian.rohde@uni-essen.de>]

Hi,

I did something else. I took the latest video4linux snapshot(as it is
quite new) and compiled my kernel(www.kernel.org 2.6.9) with just basic
video4linux support.
In my dvb-kernel cvs directory i did a cvs update -r FE_REFACTORING to
get the refactoring branch. Now i used makelinks in the dvb-kernel
directory to setup my kernel and compiled my kernel with the appropiate
modules. After that i installed the kernel and did in the video4linux
directory a make DVB=1 KDIR=/path/to/kernel
copying the resulting modules into my kernel modules directory and a
depmod -a did the rest(When using hotplug).

But i must say that i am not really sure whether it works right now
There is a registered dvb frontend with no errors but i have a tuning
problem and i do not know if it is bad as I have no DVB-T here yet(In
two weeks we'll get it here).

Perhaps this helps...
Sebastian
