FATAL: Error inserting gspca. Unknown symbol in module, or unknown parameter

I have the same error with Logitech Quickcam Messenger (046d | 08da)

Same error with Vimicro 0ac8:305b webcam. I used Ubuntu packages and http://mxhaard.free.fr/download.html tar.gz

Nov 8 16:08:09 localhost kernel: [11418.789782] gspca: disagrees about version of symbol video_device_release
Nov 8 16:08:09 localhost kernel: [11418.789790] gspca: Unknown symbol video_device_release

My cam (Logitech Communicate STX) worked perfectly with Edgy and Feisty, but with Gutsy there's no way.
After compiling the latest gspca driver, it shows the same error message as the first post:

$sudo modprobe gspca

I had the same problem, but I was able to resolve it by re-installing the packages:

linux-image-2.6.22-14-generic
linux-headers-2.6.22-14-generic
Then I ran "sudo depmod -a"

then I re-compiled gspca and thistime it worked ok when I ran "sudo modprobe gspca"

The same problem, the reinstallation of kernel didn't help. I have Logitech 046d:0921.

I had wrong headers installed: I re-installed all the kernel packages, uninstalled old headers, verified link in /usr/src and it worked (Ubuntu 7.10).
Now I've the following packages installed:

ii linux-headers-2.6.22-14 2.6.22-14.47 Header files related to Linux kernel version
ii linux-headers-2.6.22-14-generic 2.6.22-14.47 Linux kernel headers for version 2.6.22 on x
ii linux-headers-generic 2.6.22.14.21 Generic Linux kernel headers
ii linux-image-2.6.22-14-generic 2.6.22-14.47 Linux kernel image for version 2.6.22 on x86
ii linux-image-generic 2.6.22.14.21 Generic Linux kernel image
ii linux-libc-dev 2.6.22-14.47 Linux Kernel Headers for development
ii linux-restricted-modules-generic 2.6.22.14.21 Restricted Linux modules for generic kernels

ls -la /usr/src:
drwxr-xr-x 19 root root 4096 2007-12-19 14:08 linux-headers-2.6.22-14
drwxr-xr-x 5 root root 4096 2007-12-19 14:08 linux-headers-2.6.22-14-generic

I don't know if all the packages are needed, but it works.
Bye

I have the same problem with Logitech 046d:08d9

I run Ubuntu 7.10 64 bit, and I was quite sure that the webcam once worked. After that I did a reinstall, and installed my dvb-t stick using video4linux. As I was trying to connect my webcam, I got the above errormessages.

 Hello. I managed to make my webcam work doing what Nigel Pallet suggested, but applications like Camorama and such can only access it if run as superuser.
 Best regards and thanks for your kind work.

This module loaded fine for me in hardy until updating today or yesterday (hadn't used it since before yesterday). I get the same Unknown symbols in my log.

Try runing
$ make menuconfig
(leave menuconfig immediately, saving config)
$ make dep

in the kernel source dir and recompile the driver. This solved it for me (Centos 5.1)

This is neither new nor undecided. It's a real bug requiring a real fix. None of the above-mentioned tips seem to work. It's carried over into Hardy as well.

I seem to have got it to work with some modification of Nigel Pallett comments

1.) Install linux kernel image and header for 386 (not just generic)
2.) In the header directory type <i>sudo make menuconfig</i>
3.) Save and exit
4.) type <i>sudo dep</i>
5.) type <i>sudo depmod -a</i>
6.) Install gspca source in the /usr/src/ directory.
7.) Type <i>sudo ./gspca_build</i>

Not sure if this is any help, but I was having exactly the same issue.
I found a solution on the Linux DVB Mailing list archive, so I thought I'd drop it in here in case it helps anyone else.

I had downloaded the V4L-DVB tree to get my Hauppauge HVR4000 working, and did not realise that building gspca after that meant the build was against the 2.6.24 media system, not the V4L tree I had built and installed.

To get around this, I had to go into the v4l-dvb source tree and run :
sudo make kernel-links. This patched the new v4l-dvb tree into the kernel headers.

Then I ran a "make oldconfig" and just set up the new drivers as modules or just pressed 'y' when I was not sure!

depmod -ae
depmod -a

(did both as was not sure of the difference)

Then back into the gspca tree and built it again. This time when I plugged the cam in, it moaned and bitched, but worked!

HTH someone,

Bon

which kernel did you choosed ?
could you please provide an url link to the kernel you download to compile it ? is it from the trunk ?
because if you take the very last : wget -N http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.27.8.tar.bz2

it is not working anymore to compile the gspca. :(
