Build and Install OpenCV

sudo make install

OpenCV 2.4.* is now installed. Just make sure that all the libraries are linked properly. Go to samples directory in OpenCV package. Change directory to C or C++. You’ll find a script there named build_all.sh. Execute the script. It will make all the files. select any output file and run it. If it works then you are good to go.

sudo echo "/usr/local/lib" >> /etc/ld.so.conf
sudo ldconfig

Your OpenCV 2.4.* is installed and libraries are properly linked. If you don’t have much experience with OpenCV, I would suggest you to go through this post. Beginning OpenCV. It shows how to make a script so that you don’t need to add everything while compiling opencv codes.

P.S. My Python port of George Nebehay’s OpenTLD Version is almost ready.
