opencv4 is not fully backward compatible with opencv3 as "a lot of C API from OpenCV 1.x has been removed.": https://opencv.org/opencv-4-0. Moreover, it should be noted that layout of include files as well as pkg-config filename changed sincea956732874All these changes mean that most of buildroot packages (e.g. vlc, ffmpeg) are not compatible with opencv4. Here is the most important changes between opencv3 and opencv 4.5.1: - License is Apache-2.0 (https://opencv.org/opencv-4-5-0) - openjpeg is an optional dependency (enabled by default) since0384eb7d8cjpeg2000 can be enabled through openjpeg or jasper - pkg-config must be enabled with OPENCV_GENERATE_PKGCONFIG sincee755a2a6e4- cmake is not installed in /usr/share anymore so hook can be dropped - C++11 is required sinced4688e6474Signed-off-by: Fabrice Fontaine <fontaine.fabrice@gmail.com> [Arnout: remove a few redundant dependencies from Config.in] Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>
