- | The unzipped folder contains several subdirectories. These folders are essentially the installation packages and files. You need not concern yourself at all with them; the command terminal will deal with them. | + | The unzipped folder contains several subdirectories.

- | Now that the package has been fully unzipped you will need to to open a Linux Terminal. You can do this by using the Linux menu system: Applications > Sytem Tools > Terminal

| + | |
- | | + | |
- | <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

- | '''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>
