I tried to follow these instructions get OpenCV to compile on my MAC MINI, but failed at step 6:

../opencv_cmake.sh Simulator ../OpenCV-2.1.0

I got these errors, and I can’t make sense of it. Any clues?

Starting cmake...

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