Build v4l-dvb on Debian

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

I want to configure my Debian system (2.6.32 kernel) to work with a
dual DVB-T USB device. I need recent drivers to get working both
device (af9013).

There are lots of change made by Antti Palosaari that I want to
include on the build:
http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux.git&a=search&h=HEAD&st=commit&s=af9013

I install the sources this way:

mkdir /usr/local/src/dvb
cd /usr/local/src/dvb
git clone git://linuxtv.org/media_build.git
cd media_build
./build
make install

Now, both tuners works great but I have lots of dmesg: (10 lines per second)

# tail /var/log/syslog

My questions are:

1. I am missing something? Did I build it correctly?

2. Could I delete all failed message from the dmesg?

Regards.
