I've installed opencv via brew

brew install opencv3 --with-ffmpeg --with-tbb --with-contrib

add to search path in Xcode project for osx

/usr/local/include/**

/usr/local/lib/**

imported in to *.mm file

#import <opencv4/opencv2/opencv.hpp>

and now I have bunch of errors:

Unknown type name 'uint32_t' Unknown type name 'int64_t' Unknown type name 'uint64_t' No member named 'lldiv_t' in namespace 'std' No member named 'llabs' in namespace 'std' No member named 'lldiv' in namespace 'std' No member named 'atoll' in namespace 'std' No member named 'strtoll' in namespace 'std' No member named 'strtoull' in namespace 'std' No member named 'strtof' in namespace 'std'

Search path should be:

/usr/local/include/opencv4 non recursive

then imports works correctly:

#import <opencv2/opencv.hpp>

#import <opencv2/imgproc/imgproc.hpp>

#import <opencv2/ximgproc.hpp>
