Question

我正在使用Centos 7.2。我尝试使用opencv编译并安装cmake。我运行这些命令：

git clone https://github.com/opencv/opencv
cd opencv
mkdir -p build
cd build

运行命令时会出现问题：

cmake -D BUILD_opencv_gpu=OFF -D WITH_EIGEN=ON -D WITH_TBB=ON -D WITH_CUDA=OFF -D WITH_1394=OFF -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/ghome/mypath/software/try_opencv/installed ..

我尝试了很多解决方案，例如下载最新版本，使用-D BUILD_opencv_ts=0进行编译。但它们都没有帮助。我已经陷入这个问题几个小时了，我无法解决它。问题消息如下：

谢谢大家的帮助!!!

由于在下载ippicv时出现错误，如果您不严格需要，可以在cmake配置行中添加-D WITH_IPP=OFF来禁用它。

提出了一个非常相似的问题here。

也可能是更新CMake可能会解决问题。为此，如果您在Linux环境中，请考虑this guide。

为什么我不能编译opencv？
