Installation in Linux
|
|
*********************
|
|
These steps have been tested for Ubuntu 10.04 but should work with other distros as well.
|
|
|
|
Required Packages
|
|
=================
|
|
|
|
* GCC 4.4.x or later. This can be installed with:
|
|
|
|
.. code-block:: bash
|
|
|
|
sudo apt-get install build-essential
|
|
|
|
* CMake 2.6 or higher;
|
|
* Git;
|
|
* GTK+2.x or higher, including headers (libgtk2.0-dev);
|
|
* pkgconfig;
|
|
* Python 2.6 or later and Numpy 1.5 or later with developer packages (python-dev, python-numpy);
|
|
* ffmpeg or libav development packages: libavcodec-dev, libavformat-dev, libswscale-dev;
|
|
* [optional] libdc1394 2.x;
|
|
* [optional] libjpeg-dev, libpng-dev, libtiff-dev, libjasper-dev.
|
|
|
|
All the libraries above can be installed via Terminal or by using Synaptic Manager.

Getting OpenCV Source Code
|
|
==========================
|
|
|
|
You can use the latest stable OpenCV version available in *sourceforge* or you can grab the latest snapshot from our `Git repository <https://github.com/Itseez/opencv.git>`_.
|
|
|
|
Getting the Latest Stable OpenCV Version
|
|
----------------------------------------
|
|
|
|
* Go to our `page on Sourceforge <http://sourceforge.net/projects/opencvlibrary>`_;
|
|
|
|
* Download the source tarball and unpack it.
|
|
|
|
|
|
Getting the Cutting-edge OpenCV from the Git Repository
|
|
-------------------------------------------------------
|
|
|
|
Launch Git client and clone `OpenCV repository <http://github.com/itseez/opencv>`_
|
|
|
|
In Linux it can be achieved with the following command in Terminal:
|
|
|
|
.. code-block:: bash
|
|
|
|
cd ~/<my_working _directory>
|
|
git clone https://github.com/Itseez/opencv.git
|
|
|
|
|
|
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 files and output binaries.
|
|
|
|
#. Enter the <cmake_binary_dir> and type
|
|
|
|
.. code-block:: bash
|
|
|
|
cmake [<some optional parameters>] <path to the OpenCV source directory>
|
|
|
|
For example
|
|
|
|
.. code-block:: bash
|
|
|
|
cd ~/opencv
|
|
mkdir release
|
|
cd release
|
|
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
|
|
|
|
#. Enter the created temporary directory (<cmake_binary_dir>) and proceed with:
|
|
|
|
.. code-block:: bash
|
|
|
|
make
|
|
sudo make install
|
|
|
|
.. note::
|
|
|
|
If the size of the created library is a critical issue (like in case of an Android build) you can use the ``install/strip`` command to get the smallest size as possible. The *stripped* version appears to be twice as small. However, we do not recommend using this unless those extra megabytes do really matter.
