为iOS构建OpenCV失败

问题描述：

我从GitHub下载了OpenCV文件夹并按照ReadMe指令为ios构建。使用后python opencv/platforms/ios/build_framework.py ios命令我有以下错误：为iOS构建OpenCV失败

我该怎么做才能解决这个问题？

看起来你移动了你的文件，但忘记了更新命令中的路径。你是否将文件复制到文件夹中？ – GPhilo

答

如果有人在将来会有同样的问题。这个问题出现在master分支中，下载分支2.4并在PATH中添加CMake构建过程进行得很顺利

您能解释一下“在PATH中添加CMake”是什么意思？在这条指令的背景下。 http://docs.opencv.org/2.4/doc/tutorials/introduction/ios_install/ios_install.html 我已经下载了“分支2.4”，但无法理解接下来要做什么=（对不起虚拟问题并感谢。 – ZevsVU
