'''ONLY CARRY OUT THIS PAGE IF YOU CAN GET ROOT ACCESS'''

<span style="color:#ff0000"> NOTE: To install these additional libraries ensure you are using the terminal as a root user. If using a UCL computer, these libraries should already be installed and you can skip to the
next page. If these libraries are not installed contacted your system administrator for help.</span>

'''How to use terminal as root user'''

Open a command terminal (as shown on the previous page) and type
'''“su”''' into the command terminal.

You will then be prompted to enter a password. Please enter the root password that you set up
when you installed linux. When you type the password you will '''not''' see any new characters
appearing on the screen. THIS '''IS NORMAL'''. When you have entered your password, press the
return key. You should now be presented with the line:

<pre style="color: #800000; background-color: #dcdcdc">
[root@localhost your_name]#
</pre>

The first set of libraries you will need to install are the '''expat''' libraries. This library
resolves '''XML''' files. To install these libraries type the command

<pre style="color: #800000; background-color: #dcdcdc">
sudo yum install expat*
</pre>

The * makes sure that all libraries with the word “expat” are installed. When prompted to type Y or
N, type '''Y''' followed by the '''return''' key.

You will now need to install the mesa libraries. These libraries contain the visualiser '''OpenGL'''
To install these libraries type the command:

<pre style="color: #800000; background-color: #dcdcdc">
sudo yum install mesa*
</pre>

You will finally need to install the library '''cmake'''. This library allows you to build and run Geant4 simulations. Type the command

<pre style="color: #800000; background-color: #dcdcdc">
sudo yum install cmake
</pre>
