环境

硬件：树莓派 4B 4G
系统：RasberryPi OS

编译参考

Raspberry pi 树莓派安装 OpenCV 4.1.2
子豪兄教你在树莓派上安装OpenCV

错误

编译到 83% 左右的时候出现类似下图的错误(当时没截图，用 #1301 的部分出错报告)

[ 80%] Building CXX object modules/xfeatures2d/CMakeFiles/opencv_xfeatures2d.dir/src/boostdesc.cpp.o

/root/opencv/opencv_contrib/modules/xfeatures2d/src/boostdesc.cpp:646:37: fatal error: boostdesc_bgm.i: No such file or directory

compilation terminated.

modules/xfeatures2d/CMakeFiles/opencv_xfeatures2d.dir/build.make:94: recipe for target 'modules/xfeatures2d/CMakeFiles/opencv_xfeatures2d.dir/src/boostdesc.cpp.o' failed

原因

编译过程是还需要下载文件的，出现以上错误大概率网络不行，导致下载文件出错

该 issue 下的大佬提供的 tree, 正常网络好的话应该是以下的文件树

opencv/.cache

以下是我配置完后的文件树 ( 注意是2个文件夹，最好都配上吧 )
