Installing Open Scene Graph for Ubuntu 14.04 =

First install the open scene graph dependencies.

sudo apt-get build-dep openscenegraph

Now from your home directory download the open scene graph source code.

svn co http://svn.openscenegraph.org/osg/OpenSceneGraph/tags/OpenSceneGraph-3.2.1 OpenSceneGraph

Now we need to compile the code. Follow the commands (The make command took about one hour! on my desktop)

./configure
make
sudo make install

Finally we need to fix up a few paths.
