Kernel module problem - unknown symbol in module


After building 2.6.35.4, I plugged in a Logitech QuickCam Chat webcam. I tried to modprobe the gspca module for the camera, but it said module not found. I knew I checked off on this as a module so I went looking in /lib/modules/2.6.35.4. I found both that I checked.

Using insmod, it failed to load because of an unknown symbol in both modules. What would cause an unknown symbol?

This isn't a priority, I was just looking to see if this thing could be used. I've had it for two years and decided tonight to give it a go.

It usually happens when linking module with incorrect kernel version. Even though symbol may be present, incorrect version creates a problem.

have a look at this thread ->

am not sure how far it applies to Slackware but you could give it a read anyway.

It does give me a starting point. I am going back to the kernel config and see if maybe I left something out. Checking dmesg after trying to insmod a module tells me that something may be missing. I've never used video for linux yet, and usually leave it out of the config. I bet I missed something important.
