Python InterfacePython is a popular scripting language with an interactive interpreter. Geant4Py, a Geant4-Python bridge, providesa bridge for Geant4 classes. This enables to directly access Geant4 classes from Python scripting. User applicationscan be easily configured with many Python third-party modules, such as PyROOT, on the Python software bus.Geant4Py is located in the directory environments/g4py/.8.1. Installation8.1.1. Software RequirementsGeant4Py requires Boost-C++ external library, which helps Python binding of C++ codes. A Precompiled packageis available for many Linux distributions (SL, SuSE, Ubuntu, etc) and Mac OSX.Geant4 libraries can be built as "static" and "granular", where library components (variables, functions, ...) used inthe application are linked statically and shipped with the application. On the other hands, in dynamic binding, thelibrary components are not included in the application, and their binding is carried out at run time. The modularapproach of Python is based on dynamic binding mechanism, so you have Geant4 shared libraries are requiredinstead.For generic information about building Geant4 libraries, please refer to the Installation Guide.Here are some tips for manually building "global" and "shared" libraries from an already existing "static + granular"installation. After setting additional environment variables like:Environment Variable Description Value (example)G4LIBG4TMPPath where the Geant4 libraries areinstalledPath where temporary files areplaced$G4INSTALL/slib$G4INSTALL/tmp-slibG4LIB_BUILD_SHARED Flag for building shared libraries 1Table 11. Additional environment variables for building global and shared libraryexecute the following:# cd $G4INSTALL/source# make# make globalIn addition, it is required that all header files are installed in a single directory.# cd $G4INSTALL/source# make includesThis will collect all relevant header files in $G4INSTALL/include (or $G4INCLUDE).There are additional tools for helping building a Geant4 library in the directory g4py/tools/.8.1.2. Building Geant4Py moduleGeant4Py provides a configure scrtipt for building modules.# ./configure --help`configure' configures Geant4Py to adapt to many kinds of systems.303
