Question

I have followed this http://www.pyimagesearch.com/2015/06/15/install-opencv-3-0-and-python-2-7-on-osx/ to install OpenCV on my mac. When I do this step : $ make -j4 a problem happened:

fatal error: 
      'QTKit/QTKit.h' file not found
#import <QTKit/QTKit.h>
        ^ 1 error generated. make[2]: *** [modules/videoio/CMakeFiles/opencv_videoio.dir/src/cap_qtkit.mm.o]
Error 1 make[1]: ***
[modules/videoio/CMakeFiles/opencv_videoio.dir/all] Error 2 make: ***
[all] Error 2

Answer 1

Try building it like this instead:

cmake -DWITH_QUICKTIME=OFF -DWITH_GSTREAMER=OFF -DWITH_FFMPEG=OFF -DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang++ -DCMAKE_BUILD_TYPE=Release .. ; make -j4
