sudo apt-get install libjpeg62-dev libtiff4-dev libjasper-dev
Install the GTK dev library

sudo apt-get install  libgtk2.0-dev
Install Video I/O libraries

sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev

Now download OpenCV 2.4.2 to wherever you want to compile the source.

mkdir xxx
cd xxx 
wget <a href="http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.4.2/OpenCV-2.4.2.tar.bz2">http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.4.2/Op...</a>
tar -xvf OpenCV-2.4.2.tar.bz2

Opret en mappe med navnet build og konfigurere OpenCV med kommandoen cmake, du må ikke glemme at lave cmake kommandoen

cd OpenCV-2.4.2
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local
-D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON 
-D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON 
-D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON ..
Now compile it

make
And finally install OpenCV 2.4.2

sudo make install
