Ov518 drivers error

I moved to linux some weeks ago and now i'm trying to resolve the only problem i have. Installing drivers for webcam. I already searched what chip it has and i know it's supported but when i try to compile i get this errors. I don't know where the problem is. Could you help me on this?
Im running ubuntu 7.04. Thanks in advance

Welcome to LQ, fredzz2!

You do not have to torture yourself with this compilation. Drivers for your camera are included in the Linux kernel. I do not know if Ubuntu comes with this module (=kernel driver), you may try to load it with modprobe. If this does not work you need to enable it and rebuild your kernel. I insist this is much easier than finding correct driver for your kernel and building it the way you do.

Thank you Emerson.
That's right. The drivers come included. I load them with modprobe ov511. But after loading them. There is no /dev/video# created. In video0 i have a tuner card. Webcam should go to /dev/video1. But it does not get created when i load ov511 drivers.
So i created it as i read somewhere with mknod /dev/video1 c 81 0 and then "chmod 666 /dev/video1 " , But the result of this is /dev/video1 beeing also with tuner card. So now i have 2 identic devices: video0 e video1. Both with the tuner card. But no webcam.

I don't know what's the problem, because when i load the ov51x-jpeg that are hacked drivers with jpeg suport, it works perfectly in xawtv and soem more programs. But not for what i want to. Because aMSN doesn't support yet JPEG webcams.

That's why I was trying to use default drivers but it doesn't work.
Is there anything i could do?

Thanks in advance and for your reply.

Fred

You need to create new nodes with correct major and minor numbers. Major number refers to the driver, minor to the device. As usual, Google helps, here's one article I found:

Good luck.
