为iOS编译OpenCV失败-Cmake失败

问题描述

我尝试为iOS编译OpenCV.我一直都遇到这些错误.我在不同版本的opencv中尝试过，但结果是相同的.

I try to compile OpenCV for ios. I get these errors all the time. I tried it with different versions of opencv, but the result is the same.

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

I run this:python platforms/ios/build_framework.py ios_opencv_build

我安装了python，cmake和g ++编译器.有谁知道这些错误是什么意思，我应该怎么做才能成功编译?

I have python, cmake and g++ compilers installed.Does anyone have an idea what these errors mean and what I should do to compile successfully?

推荐答案

老版本的CMake似乎有问题.尝试从其网站上更新到最新的CMake(您使用的是哪个OS版本和CMake版本?)

It seems like problem with old version of CMake. Try updating to newest CMake available from their website (which OS version and CMake version do you use?)
