Installation in Linux
|
|
***********************
|
|
These steps have been tested for Ubuntu 10.04 but should work with other distros.
|
|
|
|
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
|
|
* Subversion (SVN) client
|
|
* 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 the `SVN repository <http://code.opencv.org/svn/opencv/>`_.
|
|
|
|
Getting the latest stable OpenCV version
|
|
------------------------------------------
|
|
|
|
* Go to http://sourceforge.net/projects/opencvlibrary
|
|
|
|
* Download the source tarball and unpack it
|
|
|
|
|
|
Getting the cutting-edge OpenCV from SourceForge SVN repository
|
|
-----------------------------------------------------------------
|
|
|
|
Launch SVN client and checkout either
|
|
|
|
a. 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 Ubuntu it can be done using the following command, e.g.:
|
|
|
|
.. code-block:: bash
|
|
|
|
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
|
|
|
|
.. 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.
