xcode - 让 OpenCV 在 Iphone 上工作

Question

我试着关注 these instructions让 OpenCV 在我的 MAC MINI 上编译，但在第 6 步失败:

../opencv_cmake.sh 模拟器../OpenCV-2.1.0

我遇到了这些错误，但我无法理解。有什么线索吗？

Starting cmake...

iOS SDK Version       = 4.1
iOS Deployment Target = 3.0
OpenCV Root           = ../OpenCV-2.1.0
OpenCV Install Prefix = /Users/haoest/Development/iphone_opencv_test/build_simulator/../opencv_simulator
