为什么我不能编译opencv？

-1

我正在使用Centos 7.2。我试图使用cmake编译并安装opencv。我运行这些命令：为什么我不能编译opencv？

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 ..

我已经尝试了多种解决方案，如下载最新版本，-D BUILD_opencv_ts=0编译：

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

，当我运行命令的问题发生。但他们都没有帮助。我一直被困在这个问题几个小时，我无法解决它。问题信息如下：

我想我会尝试删除和清除'cmake'包并重新安装它，然后，如果有必要，通过重新分配OpenCV github存储库 –

由于错误似乎在下载ippicv，如果你不需要它，你可以简单地禁用它，在你的cmake配置行中添加-D WITH_IPP=OFF。

一个非常类似的问题被要求here。

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

对不起，您的答案不能解决我的问题。我只是不知道我的命令有什么问题，但是当我更改为另一个版本的opencv时，我把它记下来了。我无法分辨你的答案是否正确。但你的回答并不能解决我的问题。但是仍然感谢你的帮助，我不会在你的答案中加入一个手指。 – pfc
