Getting the cutting-edge OpenCV from SourceForge SVN repository
Launch SVN client and checkout either
- the current OpenCV snapshot from here: http://code.opencv.org/svn/opencv/trunk
- or the latest tested OpenCV snapshot from here: http://code.opencv.org/svn/opencv/tags/latest_tested_snapshot
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
Building OpenCV from source using CMake, using the command line
-
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
