Hey guys,
I've been working on packaging and tweeking a few video applications
lately, and I've been getting strange errors in regards to our kernel
headers. Here's a few examples from separate application compiles:
--- re: Xvlib.h configure error ---
checking X11/extensions/Xv.h usability... yes
checking X11/extensions/Xv.h presence... yes
checking for X11/extensions/Xv.h... yes

/usr/include/linux/videodev2.h:54: '__u32' is used as a type, but is not
defined as a type.
Anyone seen this before?
Are some of our kernel headers/sources incompatible with gcc3, or are we
using outdated headers/sources? Anyone compiled xv or v4l applications
lately (against OUR kernel headers)? Any problems?
Thanks for your help,
Austin
