#先安装 cmake 3.14

# cmake安装到了 /usr/local/bin

#配置PATH

export PATH="$PATH:/usr/local/bin"

#下载最新的opencv

git clone "https://github.com/opencv/opencv.git"

git clone "https://github.com/opencv/opencv_contrib.git"

#定义自己的生成目录

mkdir 20190508

mkdir -p opencv-master/build

cd opencv-master/build

#生成配置的时候选择带上opencv-contrib

cmake -DOPENCV_EXTRA_MODULES_PATH=/home/admin/opencv/opencv_contrib-master/modules ..

#执行ccmake，配置编译选项

ccmake ..

#我配置的主要选项如下：

配置有这样一些考虑：

1.仅满足linux下的基本的图形处理的使用；

2.不要CUDA，不要各种图形格式的支持；

3.生成静态库，避免多人使用的情况下大家相互覆盖；

4.生成在自己的目录下，不放在系统目录。

 配置完成后按g，生成配置，退出。

make -j 20

make install

 

等到链接具体的程序的时候，还需要额外的一些库：

gcc -o xxx_elf xxx.o -L"/home/admin/opencv/20190508/lib64" -lopencv_core -lopencv_imgproc -lopencv_imgcodecs \

    -ldl -lz -pthread
