Macbook M1 编译安装 OpenCV 及配置 IDEA

• 下载 opencv 源码

brew install wget

wget -O opencv.zip https://github.com/opencv/opencv/archive/4.8.0.zip

wget -O opencv_contrib.zip https://github.com/opencv/opencv_contrib/archive/4.8.0.zip

unzip opencv.zip
unzip opencv_contrib.zip

• 编译安装
  进入下载路径，并创建 build 文件夹

cd opencv-4.8.0

mkdir build && cd build

在 build 文件夹 下新建 run.sh，并输入如下代码，其中BUILD_opencv_java设置为ON，OPENCV_EXTRA_MODULES_PATH 设置为下载的 opencv_contrib 的modules 路径

set -ex

cmake \
-DCMAKE_SYSTEM_PROCESSOR=arm64 \
-DCMAKE_OSX_ARCHITECTURES=arm64 \
-DWITH_OPENJPEG=OFF \
-DWITH_IPP=OFF \
-DCMAKE_BUILD_TYPE=RELEASE \
-DCMAKE_INSTALL_PREFIX=/usr/local/opencv \
-DJAVA_INCLUDE_PATH=/Library/Java/JavaVirtualMachines/jdk-1.8.jdk/Contents/Home/include \
-DJAVA_AWT_INCLUDE_PATH=/Library/Java/JavaVirtualMachines/jdk-1.8.jdk/Contents/Home/include \
-DJAVA_INCLUDE_PATH2=/Library/Java/JavaVirtualMachines/jdk-1.8.jdk/Contents/Home/include/darwin \
-DBUILD_opencv_python2=OFF \
-DBUILD_opencv_java=ON \
-DINSTALL_PYTHON_EXAMPLES=OFF \
-DINSTALL_C_EXAMPLES=OFF \
-DBUILD_ZLIB=OFF \
-DOPENCV_ENABLE_NONFREE=ON \
-DOPENCV_EXTRA_MODULES_PATH=/Users/huipeng/Desktop/AIGC/opencv/opencv_contrib-4.8.0/modules \
-DBUILD_EXAMPLES=ON ..

输入 bash run.sh 运行该命令，成功后输出:

--   OpenCL:                        YES (no extra features)
--     Include path:                NO
--     Link libraries:              -framework OpenCL
--
--   Python (for build):            /opt/homebrew/bin/python3
--
--   Java:
--     ant:                         NO
--     Java:                        YES (ver 1.8.0.381)
--     JNI:                         /Library/Java/JavaVirtualMachines/jdk-1.8.jdk/Contents/Home/include /Library/Java/JavaVirtualMachines/jdk-1.8.jdk/Contents/Home/include/darwin /Library/Java/JavaVirtualMachines/jdk-1.8.jdk/Contents/Home/include
--     Java wrappers:               YES (JAVA)
--     Java tests:                  NO

-- Configuring done (102.5s)

-- Build files have been written to: /Users/huipeng/Desktop/AIGC/opencv/opencv-4.8.0/build

然后输入如下指令编译:

make -j8

最后输入如下指令安装:

sudo make install

完成之后会在两个地方出现jar文件和lib文件，一个是build路径

opencv-4.8.0/build/bin/opencv-480.jar
opencv-4.8.0/build/lib/libopencv_java480.dylib

一个是安装路径:

/usr/local/opencv/share/java/opencv4/libopencv_java480.dylib
/usr/local/opencv/share/java/opencv4/opencv-480.jar 

• 设置 Java Library Path:

-Djava.library.path=/usr/local/opencv/share/java/opencv4

• 设置 Libraries
