Cmake编译时报错configure到后面会出现红字FFMPEG download failed,这是由于文件下载联网可能被阻断导致的。可以选择在编译文件夹找CMakeDownloadLog.txt按着链接下下来。不过有个.cmake文件是下不了的,可以选择把打开的网页保存为.txt然后转成cmake 怕麻烦的我这里也直接提供我打包好的文件了,解压放进3rdparty那个位置...
一、Configure会报一些红色的警告信息,比如: 1CMake Warning at cmake/OpenCVDownload.cmake:193 (message):2FFMPEG: Download failed: 7;"Couldn't connect to server"34For details please refer to the download log file:56D:/study/opencv_with_contrib_test_sln/CMakeDownloadLog.txt78Call Stack (most ...
提示FFMPEG下载失败,因为无法连接到服务器,打开 CMakeDownloadLog.txt 查看详细信息 二、打开CMakeDownloadLog.txt #use_cache "D:/study/opencv-4.0.0/.cache" #do_copy "opencv_ffmpeg.dll" "849286ccc527c99e5a218b67f13c6e8c" "https://raw.githubusercontent.com/opencv/opencv_3rdparty/759a23e24ab...

打开cmake-gui.exe,在source code那里选择之前解压opencv源码里的source文件夹。Where to build the binaries设置目标位置,可以自由选择没什么限制,建议设置为一个空文件夹,因为会生成一大堆文件。然后点击configure。 2. 选择编译器 弹出一个窗口,选择编译工具集。这里选择MinGW Makefiles和specify native compilers。列...
