OpenCV Installation

For Linux :

1] Install CMake and some prerequisite libraries.

(You can skip this if you just use the pre-built Visual Studio 2008/2010 binaries for Windows).

2] Untar the tarball downloaded, say OpenCV-x.y.z.tar.bz2 using the command as follows

          $ tar -xvf OpenCV-x.y.z.tar.bz2

3] Enter the new directory created for OpenCV in your current directory as follows

          $ cd OpenCV-x.y.z

4] Make a new directory here, say GUI

         $ mkdir GUI

5] Enter the newly created directory GUI 

         $ cd GUI

6] Run the following command

         $ cmake ../.

        If this command fails, check if you have "cmake" installed.

7] After the successful execution of above command run following command

         $ make

8] Again if above command runs successful,  run the following command as "ROOT"

         # make install

9] Successful completion of above command is followed by following commands:

       # PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

       # export PKG_CONFIG_PATH

   Note: If using Fedora, Kindly add the commands mentioned in "step 9" to file named ".bash_profile" in the home folder through shell and reboot the system.
10] Last Step
       #ldconfig
