- GCC 4.x or later
- CMake 2.8 or higher
- Xcode 4.0 or higher
Launch SVN client and checkout either
In MacOS it can be done using the following command in Terminal:
cd ~/<my_working _directory>
svn co http://code.opencv.org/svn/opencv/trunk
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
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
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
