Driver Install problems

[Aymeric BOUCHER]

Hello, I'm new in Linux World and beginner in computers. I've just installed Ubuntu Studio 7.10 with the kernel 2.6.22.14-rt.
I've tried to install the line6usb driver for my pod xt live but each time it failed.

1) First by compiling the sources 7.3.
But when I write make install, it say me:

...
/sbin/modprobe line6usb
FATAL: Error inserting line6usb (/lib/modules/2.6.22-14-rt/kernel/sound/usb/line6usb.ko): Unknown symbol in module, or unknown parameter (see dmesg)
make: *** [install] Error 1

and the dmesg:

[ 5732.640152] line6usb: disagrees about version of symbol snd_rawmidi_receive
[ 5732.640161] line6usb: Unknown symbol snd_rawmidi_receive
[ 5732.640233] line6usb: disagrees about version of symbol snd_ctl_add
[ 5732.640235] line6usb: Unknown symbol snd_ctl_add
...

I've no found solutions for this problem so I tried a second method.

2) Install rpm package using allien:

...
dpkg-gencontrol: error: current build architecture i386 does not appear in package's list (amd64)

My processor is a 64bits but I installed i386 version because it is sayed there are less compatibility problems with material.

3) So I try to install the deb package found here in user mailing list . the deb made by Jelmer Vernooij.
I follow the instructions ans it seemed to work because i did'nt receive any error message.
But when I write aplay-l,  my pod don't appear.

the line_6_find_device script found my pod.
but the create_links script say: ls: /sys/bus/usb/drivers/line6usb/*/modalias: No such file or directory

Here is my problem. If someone can help me he is welcome .Thank's

Try this:

sudo su
[enter password]

apt-get install build-essential linux-headers-rt

exit

now try to compile your driver

[Aymeric BOUCHER]

this package is already installed

[HogieWan]

both packages?  build-essential and linux-headers-rt?

[HogieWan]

try them separately:

apt-get install build-essential
apt-get install linux-headers-rt

I've installed i386 kernel and it work on.

[Aymeric BOUCHER]

actually, it work also on rt kernel. The problem was due to the package Linux-backports.
I removed this and now it work perfectly. (but I have lost my integrated sound card wich need this package).
