I would like to use OpenCV in BBX15 for one of my project. I tried building the OpenCV-3.4.1 but receive the compilation errors in NEON and VFP related files. Has anyone built OpenCV-3.4.1 in BBX15?
Here is the cmake command that I used for the build-
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D INSTALL_C_EXAMPLES=OFF -D INSTALL_PYTHON_EXAMPLES=OFF -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-3.0.0/modules -D BUILD_EXAMPLES=OFF …
