Running an example
From UCL HEP PBT Wiki
To test that your version of Geant4 has been successfully installed we will build and run the basic>B1 example included with the Geant4 install.
1. Create the file “B1-build” on your desktop (I would advise placing any build files / other examples you work on in a separate folder to the Geant4-install so that if you wish to update your version of Geant your work is not accidentally deleted)
2. Now change your present working directory to /home/your_name/Desktop/B1-build by typing the command
4. To build your project type the following command into the terminal
cmake -DGeant4_DIR=/home/your_name/Desktop/Geant4-install/lib64/Geant4-10.0.0 SPACE /home/your_name/Desktop/Geant4-install/share/Geant188.8.131.52/examples/basic/B1
SPACE should obviously be replaced with a space bar (do not type the word SPACE).
5. Now type the command
into the command terminal.
IF RUNNING GEANT4 ON YOUR OWN MACHINE
6. to run your example, type the following command into the terminal
This command tells the terminal where all the data files that are required to running and building your simulation are.
IF RUNNING GEANT4 ON PLUS1 SERVER TYPE THE FOLLOWING INSTEAD
PS: If you are running Geant4 on your own machine you are likely to have the latest versions of CMAKE and GCC installed. If running Geant4 on PLUS1 you will need to enter the give source command to access the latest versions. The latest version is required to run certain processes faster.
7. Finally, to open your simulation type the command
into the terminal. To run the simulation type the following commands into the terminal:
Idle> /control/verbose 2 Idle> /tracking/verbose 1 Idle> /run/beamOn 10
In order to understand what these commands mean, and how to run simulations in general using Geant4, please use the official Geant4 manual from CERN @:UserGuideForApplicationDeveloper
