Need help installing tv tuner driver in ubuntu 9.04

I'm trying to install the v4l-dvb driver that is suppose to make my hauppage tv tuner working, but when I try to compile it I get the following error:

---------------------------------------------------------------------------------
root@machine:/home/temp/v4l-dvb# make
make -C /home/temp/v4l-dvb/v4l
make[1]: Entering directory `/home/temp/v4l-dvb/v4l'
Updating/Creating .config
Preparing to compile for kernel version 2.6.34
File not found: /lib/modules/2.6.34.1-vortex86-sg/build/.config at ./scripts/mak
e_kconfig.pl line 32, <IN> line 4.
make[1]: *** No rule to make target `.myconfig', needed by `config-compat.h'. S
top.
make[1]: Leaving directory `/home/temp/v4l-dvb/v4l'
make: *** [all] Error 2
root@machine:/home/temp/v4l-dvb#
----------------------------------------------------------------------------------

I've been reading this forum and googling and I think I must recompile the kernel but there is so many options in the menuconfig that I don't know what to enable to actually make it work. Or maybe I just need to set the default options... I have no clue for the moment and since it take 3-5 hours to compile it will take me ages to find the correct options (my robot competition is in 2 months and a half).

Any idea?

I'm assuming you installed the vortex kernel headers package, probably with a command like this:
Code: Select all
dpkg -i linux-headers-2.6.34.1-vortex86-sg_1.0_i386.deb


Unfortunately, this package does not create a needed link that the v4l build process is looking for. To create the missing link yourself, enter these commands (as root):
Code: Select all
cd /lib/modules/2.6.34.1-vortex86-sg
ln -s /usr/src/linux-headers-2.6.34.1-vortex86-sg build

This creates a symbolic link (called 'build') from the kernel headers that you installed into the /lib/modules subdirectory for the current kernel version.

It looks like you already know what you're doing with regard to building the v4l-dvb driver. In case anyone who isn't sure what to do is reading this, here are the steps I used to download and install it:
Code: Select all
cd /usr/local/src
wget http://linuxtv.org/hg/v4l-dvb/archive/tip.tar.gz
tar xzf tip.tar.gz
cd v4l-dvb-1da5fed5c8b2
make all
make install
modprobe uvcvideo


After doing this, I was able to use uvc based webcams (including a Logitech c500 and Logitech Pro 9000) directly from the RoBoard.

One note - I'm running Debian 5 (lenny) on my Roboard, and I have not tested any of these instructions with other linux distros.

Thanks for the quick reply, sounds like exactly what I need. I'll be trying this tonight and post the result!

Posting result:

Actually it DID compile, thanks a lot, but after when I try to install the driver I need using modprobe:

modprobe em28xx

It says that it doesn't recognize the module em28xx.

So... I'm working on it!

It's great you got your camera working!

Could you post some information about what you did to get it to work, to help out anyone else who has a similar problem in the future? That would be a great help.

Just to mention that I didn't do anything more. It just happened that sometime later the v4l-driver created a symbolic link from /dev/v4l-dvb/[camera] to /dev/video0.

I don't know why it didnt work right away but now it's working fine.

don't know what to enable to actually make it work. Or maybe I just need to set the default options... I have no clue for the moment and since it take 3-5 hours to compile it will take me ages to find the correct options (my robot competition is in 2 months and a half).
