I was following the directions here, but with no luck.

May be you need to compile in the support for webcam into your kernel

CONFIG_VIDEO_DEV=m
CONFIG_VIDEO_PROC_FS=y
CONFIG_VIDEO_BT848=m
CONFIG_VIDEO_PMS=m
CONFIG_VIDEO_BWQCAM=m
CONFIG_VIDEO_CQCAM=m
CONFIG_VIDEO_W9966=m
CONFIG_VIDEO_CPIA=m
CONFIG_VIDEO_CPIA_USB=m

I was told that the kernel has webcam support builtin just like it does support for network cards, sound cards, etc. Any other help?

This will let you find version.h:

Code:

cd /lib/modules/2.6.18-1.2868.fc6
rm build
ln -s ../../../usr/src/kernels/2.6.18-1.2868.fc6-i586/ build

And try again. The '/' was missing on the end of the symbolic link. Try 'ls -lL' before and after to see what gets fixed.

However, I'm stuck on the next step trying to get /usr/src/kernels/2.6.18-1.2868.fc6-i586/include/linux/config.h created! Typing

Code:

cd /usr/src/kernels/2.6.18-1.2868.fc6-i586
make dep

Says "*** Warning: make dep is unnecessary now." !!!
