Good evening guys,

I am having an error when I execute the command

make -j4

on my terminal. The error is the following:

/Users/lucadigiammarino/opencv/modules/videoio/src/cap_qtkit.mm:46:9: 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

I have been following this tutorial http://www.pyimagesearch.com/2015/06/... in order to get OpenCV 3.1.0 with Python on my Mac.

This is what I execute in order to configure the build:

cmake -D CMAKE_BUILD_TYPE=RELEASE \
    -D CMAKE_INSTALL_PREFIX=/usr/local \
    -D PYTHON3_PACKAGES_PATH=~/.virtualenvs/cv3/lib/python3.4/site-packages \
    -D PYTHON3_LIBRARY=/usr/local/Cellar/python3/3.4.3/Frameworks/Python.framework/Versions/3.4/lib/libpython3.4m.dylib \
    -D PYTHON3_INCLUDE_DIR=/usr/local/Cellar/python3/3.4.3/Frameworks/Python.framework/Versions/3.4/include/python3.4m \
    -D INSTALL_C_EXAMPLES=OFF \
    -D INSTALL_PYTHON_EXAMPLES=ON \
    -D BUILD_EXAMPLES=ON \
    -D BUILD_opencv_python3=ON \
    -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules ..

Thank you for your help.

Clone the opencv repo to a new folder and don't do the checkout step i.e.

git checkout 3.0.0

The rest of the steps can be followed as mentioned in the link. This means you will be working with the dev branch instead of the release branch. The dev branch has the fix.

I missed this but I hope you skipped checking out the release branch for opencv_contrib as well. They need to be the same version.
