'opencv2/opencv.hpp' file not found

opencv, xcode

Solution

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)

Problem

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 - Always Search User Paths: YES - Framework Search Path: /usr/lib** (** stands for recursive search) - Header Search Path: /usr/lib** (** stands for recursive search) Full error message: ``` Lexical or Preprocessor Issue 'opencv2/opencv.hpp' file not found ```
