Introduction

CLHEP is intended to be a set of HEP-specific foundation and utility classes such as random generators, physics vectors, geometry and linear algebra. CLHEP is structured in a set of packages independent of any external package.

Geant4 requires the CLHEP libraries in order to compile simulations. By default Geant4 distributes a minimal version of the CLHEP library sources with the toolkit to help cross-platform usage. This internal version of the CLHEP library is built and used by default, so having an external install of CLHEP is no longer a prerequisite for Geant4.

However, the BDSIM accelerator simulation toolkit, which uses Geant4 for particle-matter interactions, requires a standalone version of CLHEP to be compiled separately from Geant4. As such, the instructions below relate to the standalone version of CLHEP.

Installation Notes

The CLHEP website provides some documentation on building and installing standalone CLHEP libraries at http://proj-clhep.web.cern.ch/proj-clhep/INSTALLATION/clhep-2.0.html .

Geant4.10.2.p01 has been tested with CLHEP 2.3.1.1. CLHEP 2.3.2.2 is available but Geant4.10.2.p01 would not compile with this version, so the previous version is installed.

For installation, CLHEP does not support installation into a sandbox directory (i.e. there are no options prefix or DESTDIR defined for command make install) and must be given the installation directory with the -prefix option. As such, to recompile CLHEP for different target directories, the configure script must be rerun with a modified -prefix /path/to/dest option. This has to be managed manually as can be seen in the installation commands below.

Installation

When downloading software, the downloaded tarball (or other Zip archive) should be placed in an appropriately named directory in /unix/pbt/software/src: the instructions below assume that the directory is /unix/pbt/software/src/clhep.

The source code should then be extracted into a suitable subdirectory in /unix/pbt/software/build. The extracted source code directory can only be deleted once the software has been built and installed.

Source Code Extraction

cd /unix/pbt/software/src/geant4-prerequisites/qt
tar -xvz -f qtbase-opensource-src-5.6.0.tar.gz
mv qtbase-opensource-src-5.6.0 qt-5.6.0

Build And Install

These instructions assume the code has already been built for the Development environment before building for the Production environment, so some of the commands for the Production install are omitted. Although it is highly discouraged to install straight to the Production environment without first compiling a Development version, it is possible to do so by adding in the directory creation commands at the start.

Development Environment

cd /unix/pbt/software/build
mkdir -pv qt/qt-5.6.0
cd qt/qt-5.6.0
../../../src/geant4-prerequisites/qt/qt-5.6.0/configure -prefix /unix/pbt/software/dev/qt-5.6.0 -release -opensource -confirm-licence -nomake tests -nomake examples -optimized-qmake -opengl -qt-xcb
make
make install

Production Environment

cd /unix/pbt/software/build/qt/qt-5.6.0
../../../src/geant4-prerequisites/qt/qt-5.6.0/configure -prefix /unix/pbt/software/prod-sl6 -release -opensource -confirm-licence -nomake tests -nomake examples -optimized-qmake -opengl -qt-xcb
make
make install
