I was hoping to get my webcam working with the latest v4l-dvb sources.
After reading about on this list and elsewhere, I ran:
# make kernel-links
from my v4l-dvb directory in order to modify my current linux sources
to use the v4l-dvb drivers. Then I went to my gspca directory and ran
the "gspca_build" script:
./gspca_build
REMOVE the old module if present

Are you using the latest gspca driver? The hardware field was removed
months ago.
[ 1026.765596] gspca: disagrees about version of symbol video_devdata
...
[ 1977.737339] gspca: Unknown symbol video_device_release
Did you "make install" the v4l tree you built against and make sure none
of the old video modules were loaded (see lsmod) when you modprobe'd
gspca?
Thanks,
Brandon
I checked the installed versions of videodev and gspca and both are
the same versions as the versions in the build directories, so they
installed fine. I also checked the depends for videodev, v4l2-common
and v4l1-compat, and those were also the correct versions.
I double checked to make sure there weren't any modules left over in
other directories in /lib/modules/`uname -r` and didn't find any.
Since the machine in question also has a PCI video4linux device in it,
the drivers for that card already load the videodev modules.

Something isn't quite right, the latest driver 20071224 is OK on the
latest 2.6.24-git kernels and the precious one 20071214 also built going
way back. These are the lines in 20071224.

Am I pulling the source from the wrong place? It came as a tarball.
Looks AOK. Mine built using "make clean && make && make install" for all
kernels, latest 2.6.24-git22.

Sid.
