I successfully installed OpenCV on Mac OS X 10.8.2.

After that I configured Xcode 4.5.2 by following this guide by SSteve even that this guide was for Xcode 3.5.1 – everything was like it’s suppose to be.

My openCV dylib’s are in: /usr/lib

  1. Always Search User Paths: YES
  2. Framework Search Path: /usr/lib** (** stands for recursive search)
  3. Header Search Path: /usr/lib** (** stands for recursive search)

Full error message:

Lexical or Preprocessor Issue
'opencv2/opencv.hpp' file not found

    Header Search Path: /usr/lib** (** stands for recursive search)

    It’s definitely wrong. You should setup this path like:

    /usr/local/include/opencv2**

    or:

    /usr/include/opencv2**

    From your link:

    In the Search Paths section set Header Search Paths to
    /usr/local/include (/opt/local/include if you used MacPorts)
