CvQueryHistValue_1D on iOS?

Question

I'm currently developing an iOS App with OpenCV framework, everything's OK until I've tried to include this line of code

value=cvQueryHistValue_1D(hist,i);

That's when XCode tells me "Use of undeclared identifier cvQueryHistValue_1D". I can't find any information about this, as many tutorials use that call and is supposed to work fine. What am I doing wrong?

Include compat.hpp

#include <opencv2/legacy/compat.hpp>
