OpenCV installation on Linux

Getting the Cutting-edge OpenCV from the Git Repository

In Linux it can be achieved with the following command in Terminal:

git clone https://github.com/opencv/opencv.git

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 files 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
   mkdir build
   cd build
   cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
   (or simply: cmake ..)
