RE: RE: Re: [Ltib] how to build a kernel module using ltib? (docu)

Hi folks,

<resend after subscribing to the list - sorry if this is then repeated>

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,
