Hello I try to build OpenCv on my Raspberry Pi 3 with Ubuntu 16.04. But when I try to build it with Arm Neon enabled My cmake Command is this one:
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_WITH_DEBUG_INFO=OFF -D BUILD_DOCS=OFF -D BUILD_EXAMPLES=OFF -D BUILD_TESTS=OFF -D BUILD_opencv_ts=OFF -D BUILD_PERF_TESTS=OFF -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=OFF -D OPENCV_EXTRA_MODULES_PATH=/home/flexpi/opencv_contrib/modules -DBUILD_opencv_python=OFF -D ENABLE_VFPV3=ON -DENABLE_NEON=ON -D WITH_LIBV4L=ON -D WITH_TBB=ON ..
I get this Error.
