Hi David,
You'll have to ask the maintainer of videodev how to build it, I'm not
familiar with this.
As far as ltib goes, there is a module example. If you do:
$ ./ltib hello_mod -m prep
It will unpack a module example. You can the take a look at the files
in rpm/BUILD/hello_mod-1.2, which include:
COPYING Makefile message_mod.c mod_main.c README
The README has some explanations and also some links to further
information regarding building modules.
To actually build this example:
$ ./ltib -p hello_mod
If you're still having problems after then, please get back in
touch on
the list. You'll need to say how your building the videodev module.
Regards, Stuart

Hi folks,

I am having a related problem: I am setting up to use the ov511
camera and the usbvideo usb capture device. Both depend on the
videodev module. When I modprobe videodev, I get "Unknown symbol
request_module" error and the probe fails. Yet I have verified that
kmod.o exports this label. I am guessing that there is something
missing from the link commands for building videodev, but I have not
yet been able to find the file that contains that invocation. Forcing
as rebuild by deleting kmod.o and videodev.o does not fix the
problem. Has anybody any ideas on this?
update:
I was getting this response to modprobe:
11:59 PM root DavesHybrid ~]$ modprobe videodev
videodev: Unknown symbol request_module
insmod: cannot insert `/lib/modules/2.6.13.4/kernel/drivers/media/
video/videodev.ko': Unknown symbol in module (-1): No such file or
directory
modprobe: failed to load module videodev
then I deleted videodev.o, ran ./ltib -- configure, forgot to check
kernel build, then ran it again with kernel build, and now I get this
response instead:
[12:06 AM root DavesHybrid ~]$ modprobe videodev
modprobe: QM_MODULES: Function not implemented
modprobe: QM_MODULES: Function not implemented
modprobe: Can't locate module videodev
[12:07 AM root DavesHybrid ~]$ find / -name videodev.* -print
/lib/modules/2.6.13.4/kernel/drivers/media/video/videodev.ko
[12:08 AM root DavesHybrid ~]$
Also, and btw, I think the sample_ltib_ko.tgz would be a great help,
but it does not show as a link; where would I find it?
thanks in advance,
David Warman
