Building Static Link Version of OpenCV

If you want to build it from source code, you can do by next steps.

  1. Building OpenCV requiers CMake. You can easily install it by using Homebrew or MacPorts.

    # Using Homebrew
    % brew install cmake
    # Using MacPorts
    % sudo port install cmake
    
  2. Clone this project from github.com, then move into the project directory

    % git clone git://github.com/niw/iphone_opencv_test.git
    
  3. Getting source code from sourceforge. I tested with OpenCV-2.2.0.tar.bz2.

  4. Extract downloaded archive on the top of demo project directory

    % tar xjvf OpenCV-2.2.0.tar.bz2
    
  5. Apply patch for iPhone SDK

    % cd OpenCV-2.2.0
    % patch -p1 < ../OpenCV-2.2.0.patch
    
  6. Following next steps to build OpenCV static library for simulator. All files are installed into opencv_simulator directory. When running make command, you've better assign -j option and number according to number of your CPU cores. Without -j option, it takes a long time.

    % cd ..
    % mkdir build_simulator
    % cd build_simulator
    % ../opencv_cmake.sh Simulator ../OpenCV-2.2.0
    % make -j 4
    % make install
    
  7. Following next steps to build OpenCV static library for device All files are installed into opencv_device directory.

    % cd ..
    % mkdir build_device
    % cd build_device
    % ../opencv_cmake.sh Device ../OpenCV-2.2.0
    % make -j 4
    % make install
