Occasionally CERN will release patches or updates for Geant4. To update your version of Geant4 you will need root-access (using command '''“su”'''). '''Before carrying out this process PLEASE make sure that you back-up any work that you have saved in the Geant4-build or Geant4-install directories.''' 1. Open a command terminal and log in as root user. Type '''“su”''' followed by your password when prompted 2. Change the present working directory to the Geant4-build directory using the command: <pre style="color: #800000; background-color: #dcdcdc"> cd /home/your_name/Desktop/Geant4-build </pre> 3. Type the command: <pre style="color: #800000; background-color: #dcdcdc"> make uninstall </pre> 4. When this is done you will need to delete the folders Geant4-install and Geant4-build. To do this change your present working directory to the Desktop using the command <pre style="color: #800000; background-color: #dcdcdc"> cd/home/your_name/Desktop </pre> 5. Now type the following command to delete the Geant4-build folder: <pre style="color: #800000; background-color: #dcdcdc"> rm –rf Geant4-build </pre> 6. When this is finished type the following command to delete the Geant4-install folder: <pre style="color: #800000; background-color: #dcdcdc"> rm –rf Geant4-install </pre> 7. Type the command '''exit''' to quit root-user mode 8. Now download the updated version of Geant4 and install it as directed by pp. 4-5 (using cmake –DCMAKE…..)
