I am using cmake version 3.5.2 and g++ (GCC) 5.2.0 version to build opencv with tag 3.1.0.
I use following command to configure the build:
cmake -D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=$HOME/local \
-D INSTALL_C_EXAMPLES=ON \
-D WITH_FFMPEG=OFF \
-D WITH_V4L=OFF \
-D WITH_LIBV4L=OFF \
-D INSTALL_PYTHON_EXAMPLES=ON \
-D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules \
-D BUILD_EXAMPLES=ON \
-D WITH_SDL2APPLICATION=OFF .."
I could resolve a couple of errors I got, but not this. Would be great if someone could help!
Determining if the system is big endian passed with the following output:
