Question

我尝试为ios编译OpenCV。我一直都会遇到这些错误。我尝试使用不同版本的opencv，但结果是一样的。

我运行这个： python platforms / ios / build_framework.py ios_opencv_build

我安装了python，cmake和g ++编译器。有没有人知道这些错误意味着什么以及我应该怎样做才能成功编译？

看起来像旧版CMake的问题。尝试从他们的网站更新到最新的CMake（你使用哪个操作系统版本和CMake版本？）

另见：http://answers.opencv.org/question/6789/problem-with-installation-opencv/ 这个（我认为这个问题很相似）：https://github.com/urho3d/Urho3D/issues/308
