Geant4Py
|
|
========
|
|
|
|
_A set of python modules for using Geant4_
|
|
|
|
|
|
System Requirements
|
|
-------------------
|
|
|
|
### CMake
|
|
Building system is migrated to CMake system.
|
|
|
|
### Python
|
|
|
|
Python2.x and Python 3.x (experimental)
|
|
|
|
### Boost
|
|
|
|
Boost_Python is needed.
|
|
|
|
### (Optional)
|
|
|
|
ROOT for histogramming/analysis
|
|
|
|
### Tested Platforms
|
|
|
|
* CentOS7 (Python2)
|
|
* Ubuntu 18.04 LTS (Python3)
|
|
|
|
How to Install
|
|
--------------
|
|
Before building library, *GEANT4_INSTALL* environment variable should be set.
|
|
|
|
# export GEANT4_INSTALL=<Geant4 install path> (zsh, bash)
|
|
# setenv GEANT4_INSTALL <Geant4 install path> (csh)
|
|
(G4 install path is the path specified by "CMAKE_INSTALL_PREFIX" when building Geant4)
|
|
|
|
then
|
|
|
|
# mkdir build
|
|
# cd build
|
|
# cmake ..
|
|
# make
|
|
# make install
|
|
|
|
By default, g4py is installed in \<g4py\>/lib(64) directory.
|
|
|
|
Before doing tests with CTest, you have to set environment variables
|
|
for Geant4 data.
|
|
|
|
# make
|
|
# make install
|
|
# ctest
|
|
|
|
performs automatic unit/integration tests with CTest.
|
|
|
|
How to Use:
|
|
-----------
|
|
Some environment variables are required at run time.
|
|
|
|
### *PYTHONPATH*
|
|
|
|
Python module search directories, given by a colon-separated list of directories, like
|
|
|
|
|
|
# export PYTHONPATH=<g4py>/lib64:<g4py>/lib64/examples:<g4py>/lib64/tests (zsh, bash)
|
|
# setenv PYTHONPATH <g4py>/lib64:<g4py>/lib64/examples:<g4py>/lib64/tests (csh)
|
|
|
|
### *LD_LIBRARY_PATH*
|
|
|
|
You might need define LD_LIBRARY_PATH for Geant4 libraries.
|
|
# export LD_LIBRARY_PATH=<Geant4 install path>/lib (zsh, bash)
|
|
# setenv LD_LIBRARY_PATH=<Geant4 install path>/lib (csh)
|
|
|
|
### Getting started
|
|
You can import Geant4Py modules in Python just like
|
|
|
|
>>> import Geant4
|
