HowToBuild

How to build and run this geant4 sample code.

1. Change the current directory to “geant4-example_compton"

$ cd geant4-example_compton**

2. Create a directory of "build", and change the current directory to "build" directory.

$ mkdir build
$ cd build

3. Cmake

$ cmake -DGeant4_DIR=/Home/Geant4/einstall/lib64/Geant4-9.6.4 ../source
  • The path of -DGeant4_DIR (/Home/Geant4/...) should be changed according to your geant4 installation location.
  • If cmake doesn't suceed because of some errors, please remove invisible files such as ~*.cc or ~*.hh in source/src or source/include, which might cause the cmake errors.

4. Make (Build)

$ make

5. Check geometry and beam condition with Qt.

$ ./exampleB3

In Qt window, you can check beam condition by running the macro file by put /control/execute run.mac in Session.

6. Obtain data with macro file (run.mac)

$ ./exampleB3 run.mac

or

$ ./exampleB3 run.mac > /dev/null 2>&1
Caution!

Please build (make) again whenever changing source files or header files, otherwise, those changes happened after the last make (build), would not be reflected to the simulation.
