在制作期间错误发生了

这是错误出现之前的程序

1.从opencv的github和opencv_contrib 4.3.0下载源代码

2.在opencv源码目录名下创建一个目录opencv_contrib

3.进入构建目录并输入代码

cmake -D CMAKE_INSTALL_PREFIX=/usr/local -D CMAKE_BUILD_TYPE=Release -D OPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules ..

cmake 未下载时要下载的一些文件，但我手动下载了这些文件，并且所有下载失败的文件都被复制到所需的路径

然后开始制作

make -j7

制作时出错

我在 4.3.0 版本中遇到了同样的问题，SIFT 已从 xfeatures2d 中移出，但我认为它没有插入到 4.3.0 版本的主分支中。只需下载master（开发）分支，问题就解决了
