Newer gcc-4.6 in rawhide seems to dislike some of opencv's headers:

Comment 1 Rex Dieter 2011-02-03 19:48:51 UTC

Per $SUBJECT, this usually means there's a missing
#include <cstddef>

Comment 2 Nicolas Chauvet (kwizart) 2011-02-03 20:46:33 UTC

This is fixed already in git for rawhide, but then there is another problem with V4L1 that was removed. So It's still in FTBFS state.

Do you browse cvs commit ?

Comment 3 Rex Dieter 2011-02-03 21:13:34 UTC

oh, fun. 2 levels of ftbfs. :)

Comment 4 Nicolas Chauvet (kwizart) 2011-02-04 14:47:32 UTC

Just fixed - bugs are opened upstream.
