Running Geant

Using the pre-installed version on aztec.iac.isu.edu

Aztec has a system-wide installed version of geant4 that may be easier to use than compiling and installing your own version. This version uses qt4, xaw, xm, opengl, raytracer, and openinventor visualization plugins.

The examples need to be copied and Configure run once to set up the environment.

oborn@aztec:~$ mkdir geant4
oborn@aztec:~$ cd geant4/
oborn@aztec:~/geant4$ cp -r /opt/geant4/geant4.9.3.p02/examples ./
oborn@aztec:~/geant4$ /opt/geant4/geant4.9.3.p02/Configure 
                --- Geant4 Toolkit Installation  ---
                 (setting environments for USER )
---------------------------------------------------
The Geant4 toolkit installation was found.
The files env.[c]sh will be copied to your current directory.
For setting Geant4 environments you should make:
. env.sh
It will also check G4WORKDIR setting and set it to
your HOME if needed.
You can use these files also for further modifications
(adding your own environments).
---------------------------------------------------

". env.sh" needs to be run after every login (or it can be added to .bashrc)

oborn@aztec:~/geant4$ . env.sh 
On this machine the G4SYSTEM=Linux-g++
On this machine the G4INSTALL=/opt/geant4/geant4.9.3.p02
On this machine the G4LIB=/opt/geant4/geant4.9.3.p02/lib
On this machine the G4LEVELGAMMADATA=/opt/geant4/PhotonEvaporation2.0
On this machine the G4RADIOACTIVEDATA=/opt/geant4/RadioactiveDecay3.2
On this machine the G4LEDATA=/opt/geant4/G4EMLOW6.9
On this machine the G4NEUTRONHPDATA=/opt/geant4/G4NDL3.13
On this machine the G4ABLADATA=/opt/geant4/G4ABLA3.0
On this machine the G4REALSURFACEDATA=/opt/geant4/RealSurface1.0
On this machine the CLHEP_BASE_DIR=/opt/clhep_2.1.0.1
......
On this machine the QTMOC=/usr/bin/moc-qt4
On this machine the G4LIB_BUILD_SHARED=1

Now the example can be built just by calling make in the directory.

oborn@aztec:~/geant4$ cd examples/novice/N01/
oborn@aztec:~/geant4/examples/novice/N01$ make
Making dependency for file exampleN01.cc ...
......
Using global libraries ...
Linking exampleN01
... Done!

And the example can be run but calling the newly-created excutable:

oborn@aztec:~/geant4/examples/novice/N01$ ~/geant4/bin/Linux-g++/exampleN01
