Tips for building ICE-BA on Banana Pi M3
OpenCV installation 0. Build M3 Bsp code for installing cross-compile tool $ git clone https://github.com/BPI-SINOVOIP/BPI-M3-bsp.git $ cd BPI-M3-bsp $ mkdir -p linux-sunxi/output/lib/firmware $ sudo ./build.sh Then choose building kernel only: mode 3 1. Use cmake-gui to configure and generate makefile. (1) CMAKE_BUILD_TYPE: Release (2) CMAKE_EXE_LINKER_FLAGS: -lpthread( or pthread) -lrt -ldl (Manually modify this part in CMakeCache.txt file) * Also remember to modify file : common.cc [1] (3) CMAKE_INSTALL_PREFIX: /usr/local (4) OPENCV_GENERATE_PKGCONFIG: True (5) OPENCV_EXTRA_MODULE_PATH: ~/opencv4.3.0/opencv_contrib-4.3.0/modules (6) BUILD_ZLIB: True (7) ZLIB_INCLUDE_DIR: ~/opencv4.3.0/3rdparty/zlib (8) CMAKE_C_FLAGS: -O3 -fPIC (9) CMAKE_CXX_FLAGS: -O3 -fPIC * Command line: sudo cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local -DOPENCV_GENERATE_PKGCONFIG=On -DOPENCV_EXTRA_MODULE_PATH=../opencv_contrib-3.4.3/modules/ -DB
