Question

I try to get my EyeTracking system running again. I know there are already some questions covering the same issue (How to compile OpenCV for iOS7 (arm64)), but nothing of that worked for me. The latest release on github has already all the arm64 architecture add ons build in. So I dont have to change the python build_framwork.py. But following the build instructions for the framework on OpenCV documentation (http://docs.opencv.org/doc/tutorials/introduction/ios_install/ios_install.html#ios-installation) brings up the following error in terminal:

sh: cmake: command not found

        names = os.listdir(src)
    OSError: [Errno 2] No such file or directory: '../build/iPhoneOS-arm64/install/include/opencv2'

Can someone tell me how I can fix that or what the problem is?

Was it helpful?

Solution 

sh: cmake: command not found

This project uses cmake to build, it's a command line utility. cmake is not included on Mac OS X as a part of the Xcode 5 tools - you need to install it yourself. http://www.cmake.org/cmake/resources/software.html
