我已经在我的机器上安装了opencv。我现在正在尝试安装一个额外的模块。但它失败了，我不明白我做错了什么。
我尝试执行以下命令：
$ cd <opencv_build_directory>
$ cmake -DOPENCV_EXTRA_MODULES_PATH=<opencv_contrib>/modules <opencv_source_directory>
$ make -j5
来源：https://github.com/opencv/opencv_contrib
但是当我尝试执行此操作时：
cmake
-DOPENCV_EXTRA_MODULES_PATH=/home/yalishanda/Downloads/opencv_contrib-master/modules -D CMAKE_INSTALL_PREFIX=/usr/local ..
我明白了：

有人可以解释一下我的错误吗？
我尝试按如下方式安装qt5，但这些错误仍然存在：
sudo apt-get remove qt5-default qttools5-dev-tools && sudo apt-get autoremove && sudo apt-get clean && sudo apt-get autoclean
sudo apt-get install qt5-default qttools5-dev-tools
答案 0 :(得分：0)
确保您使用的opencv_contrib模块版本与主opencv库相同。您似乎正在使用版本3.1.0，对于可以下载相应opencv_contrib的主库（here）。
关于QT部分，它看起来像是一个警告，但您可以检查安装libqt5gui5，libqt5concurrent5和libqt5widgets5是否会解决此问题。
如果仍有错误，请尝试删除导致这些错误的模块（例如tinydnn和dnn_modern）。
