我正在使用OpenCV_contrib在Linux上构建OpenCV，但我无法使其正常运行。 仅OpenCV即可构建而不会出错。
仅编译OpenCV时，可以正常工作。
cmake -D OPENCV_EXTRA_MODULES_PATH = .. / .. / opencv_contrib-3.4 / modules ..
$ make j5
在制作过程中，它以100％失败，

我从官方网站下载了opencv源代码，并从Github克隆了opencv_contrib。这不是一个好主意，我遇到了问题。
我从Github克隆了opencv和opencv_contrib的完全相同的版本，这次它运行良好。
git clone -b 3.4 https://github.com/opencv/opencv
git clone -b 3.4 https://github.com/opencv/opencv_contrib
答案 1 :(得分：-1)
在make clean和cmake之前运行make应该可以解决问题。
