1. 版本

以安装opencv-4.3.0和opencv_contrib-4.3.0为例子，其他版本编译原则上步骤一样，但需确保opencv和opencv_contrib的版本号一致，避免版本差异导致编译错误。

2.源码编译和安装opencv和opencv_contrib

(1) 下载opencv和opencv_contrib源码

• opencv-4.3.0：Release OpenCV 4.3.0 · opencv/opencv · GitHub
• opencv_contrib-4.3.0：Release 4.3.0 · opencv/opencv_contrib · GitHub

(2) 安装 OpenCV相关依赖库

首先安装 OpenCV 所需要的依赖库，在终端依次执行以下命令：

sudo apt-get update
sudo apt-get install build-essential
sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

(3) 源码编译

解压 opencv-4.3.0和opencv_contrib-4.3.0目录，然后进入到 opencv4.3.0 的目录，新建一个目录build，用于保存输出，命令行如下：

# 新建一个目录build，用于保存输出
mkdir build
cd build

配置 OpenCV 工程文件，其中opencv_contrib填写你自己opencv_contrib-4.3.0中的modules文件夹所在的路径：

#opencv_contrib的modules文件夹所在的路径
opencv_contrib=/home/dm/app/opencv_contrib-4.3.0/modules
 
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_EXTRA_MODULES_PATH=$opencv_contrib ..

cmake完成后，会输出类似如下的信息：

 最后开始编译并安装opencv

make -j4
sudo make install

(4) android studio中使用opencv_contrib

GitHub - chaoyangnz/opencv3-android-sdk-with-contrib: Build OpenCV3 Android SDK with contrib modules

3.一些异常处理

1.undefined reference to `TIFFReadDirectory@LIBTIFF_4.0'

 安装TIFF 下载地址：Index of /libtiff/ ，tiff-4.0.4.tar.gz (tiff-4.0.x以上亦可)

   # 解压tar -zxvf tiff-4.0.4.tar.gz
   # 进入tiff目录
   ./configure
   make
   sudo make install

然后，重新编译opencv,并加上编译选项：-D BUILD_TIFF=ON

cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_TIFF=ON  -D OPENCV_EXTRA_MODULES_PATH=$opencv_contrib ..

2.usr/lib/x86_64-linux-gnu/libvtkIOImage-6.3.so.6.3：对‘TIFFReadDirectory@LIBTIFF_4.0’未定义的引用

 可能是跟本地anaconda安装的库有冲突，可以先把anaconda的路径注释掉，再重新编译，参考：https://github.com/lagadic/visp/issues/109

确保安装了tiff库，新编译opencv,并加上编译选项：-D WITH_VTK=OFF -D BUILD_TIFF=ON

cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_VTK=OFF -D BUILD_TIFF=ON  -D OPENCV_EXTRA_MODULES_PATH=$opencv_contrib ..

4.Windows安装opencv和opencv_contrib
