##### System information (version)

  • OpenCV => 3.3.0
  • Operating System / Platform => Linux Ubuntu 16.04 LTS
  • Build tool => cmake version 3.5.1 ; GNU Make 4.1

##### Detailed description

I have downloaded opencv and opencv_contrib as follows:

opencv : wget -O opencv.zip https://github.com/Itseez/opencv/archive/3.3.0.zip opencv_contrib : wget -O opencv_contrib.zip https://github.com/Itseez/opencv_contrib/archive/3.3.0.zip

##### Steps to reproduce

I am running the following commands:

cd opencv-3.3.0

mkdir build

sudo cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D INSTALL_PYTHON_EXAMPLES=ON -D INSTALL_C_EXAMPLES=OFF -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib-3.3.0/modules -D PYTHON_EXECUTABLE=~/.virtualenvs/cv/bin/python -D BUILD_EXAMPLES=ON ..

make -j4

It fails on the last command, after building for 14%.
