Getting the cutting-edge OpenCV from SourceForge SVN repository

Launch SVN client and checkout either

  1. the current OpenCV snapshot from here:
  2. or the latest tested OpenCV snapshot from here:

In MacOS it can be done using the following command in Terminal:

cd ~/<my_working _directory>
svn co

Building OpenCV from source using CMake, using the command line

  1. Create a temporary directory, which we denote as <cmake_binary_dir>, where you want to put the generated Makefiles, project files as well the object filees and output binaries

  2. Enter the <cmake_binary_dir> and type

    cmake [<some optional parameters>] <path to the OpenCV source directory>

    For example

    cd ~/opencv
    cd ..
    mkdir release
    cd release
    cmake -GXcode -DCMAKE_TOOLCHAIN_FILE=../opencv/ios/cmake/Toolchains/Toolchain-iPhoneOS_Xcode.cmake -DCMAKE_INSTALL_PREFIX=../OpenCV_iPhoneOS -DCMAKE_BUILD_TYPE=RELEASE ../opencv
  3. Enter the created temporary directory (<cmake_binary_dir>) and proceed with:

    xcodebuild -sdk iphoneos -configuration Release -target ALL_BUILD
    xcodebuild -sdk iphoneos -configuration Release -target install install
