You need to have installed and "configured" the kernel sources in order to 
be able to compile a kernel driver. For example you need the 
"linux/config.h" file mentioned above.

Once you got past the basics of compiling drivers, you may go to 
http://lists.saillard.org/mailman/listinfo/pwc for driver-specific help.

This is assuming that you need to compile a kernel driver in the first 
place. It's not really fun, so, most people get a precompiled set of 
drivers (that includes pwc.ko) and they don't touch any form of kernel 
source code.

AND this is assuming that pwc is the driver you need. There are at least 
four generations of QuickCams. pwc was most popular some years ago, but 
then Logitech switched to using the UVC protocol, so now, you need to load 
uvcvideo.ko if you have those cams. QuickCam Pro 4000 are the last cams of 
the main series to be PWC (Philips chip). Some lower-priced series 
continued with PWC for a while (well, they still were sold in 2007 and I 
didn't check after that).
