B. Download the libcv libraries and untar it on a local directory. You can download it from here: http://opencv.willowgarage.com/wiki/
C. Compiling the libcv library and headers
cd /home/javier/Desktop/OpenCV-2.3.1/
mkdir release
cd release
cmake D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_EXAMPLES=ON ..
My results:

D. Installing the libraries and headers
make
sudo make install
sudo make install
E. Our first opencv project with Eclipse
1. Open Eclipse and add a new 'Hello World' C++ project
3. For our first project we will just open and display an image. Include the following code in your main method:
Note that it is supposed that it exists a picture called 'gnu-linux.jpg' on the folder /home/javier/Desktop/
Compile your project and run it. If you have have problems running your project:
error while loading shared libraries: libmytestsharedlibrary.so: cannot open shared object file: No such file or directory
Create the following file :
/etc/ld.so.conf.d/opencv.conf
Add the following line:
/usr/local/lib
And execute the following command:
sudo ldconfig
Explanations about all this process can be found as well in my previous post.
If everything went ok the system should have prompted your picture:
