hmm... would those be unresolved symbols in relation to dvb frontends?

This would be because we only recently merged the cvs trees, and the
older builds dont include the dvb frontends in the v4l build. You can
fix it by doing the following:

Be sure to "make clean" before and after each checkout -- it's necessary
because of what the scripts below do to the build configuration.

Before running make (EACH TIME) do this:

1- edit v4l-dvb/v4l/scripts/merge-trees.sh ... delete everything
BETWEEN these two lines... being sure to leave both of them intact.:

#!/bin/sh

...

patch -p2 <<'DIFF'

...do the same thing to v4l-dvb/v4l/scripts/unmerge-trees.sh

You will have to do it for each checkout, unfortunately. If you are
using a more recent checkout (past few days) then you do not have to
edit these files, as they have been deleted when the build was updated
for the merger of v4l+dvb cvs.

2) make merge-trees

3) make

4) make install

...because of the "merge-trees" command, you'll have to run "make clean"
each time before you cvs check out (cvs co) again.

I hope this works........
