[Digikam-devel] Solution to OpenCV «error: ‘ptrdiff_t’ does not name a type»

[Simon A. Eugster]

Perhaps someone else is interested in this as well since it prevented me 
from building digikam and frei0r-plugins on debian sid. The manual fix is 
simple (found by googling after some time):

i.e. just add «using std::ptrdiff_t;» to the cxcore.hpp file.
