2)Install the python development headers

sudo apt-get install python-dev

3)Download the source code: 
http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.3/

4)Go to the directory where OpenCV is downloaded via the terminal only and then un zip the package:
(note:- It is recommended that you move the downloaded OpenCV package to the home/<user> directory

tar -xvf OpenCV-2.3.1a.tar.bz2

cd OpenCV-2.3.1/
 
5)Now make a new directory called build and go in to it
mkdir build
cd build

6)Run Cmake

cmake -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=OFF -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON ..

7)Now make

make

8) Make it permanent

sudo make install


9)Configuring OpenCV for using shared libraries:

sudo gedit /etc/ld.so.conf.d/opencv.conf

Add the following line at the end of the file (it may be an empty file, that is ok) and then save it:

/usr/local/lib

Close the file and run the following command to configure the library:

sudo ldconfig

OR RUN : export LD_LIBRARY_PATH=/usr/local/lib
10)Open your .bashrc file and add the following:
gedit .bashrc

sudo gedit /etc/bash.bashrc


add the following at the end of the file -
 

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH

Save and close the file

11) Reboot the system
