These steps have been tested for Ubuntu 10.04 but should work with other distros.
GCC 4.4.x or later. This can be installed withsudo apt-get install build-essential
CMake 2.6 or higher
Subversion (SVN) client
GTK+2.x or higher, including headers (libgtk2.0-dev)
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
You can use the latest stable OpenCV version available in sourceforge or you can grab the latest snapshot from the SVN repository.
Launch SVN client and checkout either
In Ubuntu it can be done using the following command, e.g.:
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>
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:
make sudo make install
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.
