How to compile and run the G4 simulation

• cd path/to/PolOptSim/build

  • Go to the 'build' directory of the 'PolOptSim' simulations

• ../g4cmake.sh ..

  • Inside the 'build' directory, you should run 'cmake ../'. This will automatically setup everything for you regarding Geant4, ROOT, scripts, etc. It will produce a Makefile. It will also create a 'bin' (for all binaries) and a 'data/G4out' (for simulation files) directory.

• make -jN

  • Compile by replacing N by the number of cores you want to use.

• ./OptSim gps.mac run.mac -c config.mac -o output.root

  • Run the simulations. To run with visualization, use the '-g vis.mac' option.
