I confirm this bug and that it's serious since it prevents other
packages to build in SID with the newest g++ 4.6.
However, it can be very easily fixed by patching one single line, as
shown in the attached patch (also copied below):
=============================
diff -w -rupN OpenCV-2.1.0//include/opencv/cxcore.hpp
opencv-2.1.0//include/opencv/cxcore.hpp
--- OpenCV-2.1.0//include/opencv/cxcore.hpp 2010-04-06 03:24:40.000000000
+0200
+++ opencv-2.1.0//include/opencv/cxcore.hpp 2011-05-08 19:56:53.759113108
+0200
@@ -66,6 +66,7 @@ namespace cv {
using std::vector;
using std::string;
+using std::ptrdiff_t;
template<typename _Tp> class CV_EXPORTS Size_;
template<typename _Tp> class CV_EXPORTS Point_;
============================
Please, could a maintainer patch this package and issue a new rebuild??
BTW: After fixing this bug OpenCV seems not to completely build due to
a similar bug in the headers of libavcodec, but perhaps they've
already patched it too in SID.
Cheers,
Jose Luis
