[Ekiga-devel-list] problems compiling v4l2

[Kilian Krause <kk verfaction de>]

Hi guys,

as some of you may already have noticed, there are no really current
Ubuntu snapshots from CVS since some time (for all architectures). For
some reason the v4l2 test fails on Ubuntu due to the other headers that
are pulled in by autoconf. The result from configure (taken from
plugins/config.log on ppc dapper) is as follows:

-(snip)-
configure:3979: checking for linux/videodev2.h
configure:4000: gcc -c -g -O2  conftest.c >&5

Someone got any idea how to cleanly fix this and can bring forth a proper patch
to apply upstream?
