Geant4 is probably the most difficult application to install of SLIC's dependencies, because there are a lot of options. I will describe a minimal installation procedure with support for built-in UI and visualization drivers. drivers You can always update the libraries later if you decide to change these settings.
| Warning |
|---|
The default Geant4 library settings for WIN32 are global and static. You may choose other settings, but this could require changes in installation settings "down the line" that I may not mention. |
- Return to the work dir, create a Geant4 work subdir and go into it.
No Format cd $sim_work mkdir geant4 cd geant4
- Download the Geant4 tarball.
No Format wget http://geant4.cern.ch/geant4/source/source/geant4.7.0.p01.tar.gz
- Unzip it.
No Format tar zxvf geant4.7.0.p01.tar.gz
- Setting the following variables in $sim_work/setup.sh should allow you to compile without running the ./Configure script.
No Format G4INSTALL=${sim_wrk}/geant4/geant4.7.0.p01 G4SYSTEM=WIN32-g++ - Go into the Geant4 install dir.
No Format cd geant4.7.0.p01
- Build the libraries. These will be placed at $G4INSTALL/lib/WIN32-g++. (Maybe you should let this run overnight!)
No Format make
- Build the physics list libraries. These will go into $G4INSTALL/lib/plists/WIN32-g++.
No Format cd ../physics_lists/hadronic make cd ../electromagnetic make
- Install the headers.
No Format make includes
...
LCPhys
- Go back to the work dir.
No Format cd $sim_wrk
- Checkout the physics list from CVS.
No Format cvs -d :pserver:anonymous@cvs.freehep.org:/cvs/lcd checkout LCPhys
- Assuming that the environment from the Geant4 installation is still in place, you can build this like any other physics list.
No Format cd LCPhys make
- Set the LCPhys variable in setup.sh.
No Format LCPHYS_BASE=$sim_wrk/LCPhys
