Simulator Distribution

Overview

The Geant4-based simulator SLIC requires the following 8 software packages.

Geant4
CLHEP
GDML
LCDD
LCIO
LCPhys
Xerces C++
SLIC

The SimDist CVS project provides a build system for these programs based on GNU Make and Autoconf. Users do not need to download and install each package manually (which can be a lengthy and tiresome process). SLIC can be built from scratch using the proto-typical "configure" and "make" commands, and it includes a run script for setting up runtime dependencies (basically just the Xerces library) and launching the program.

As of March 2006, SimDist is still a beta-level package, missing many planned features.

 

Known Working Configurations

This is a list of known combinations of operating system and compiler (gcc).

Red Hat Enterprise Linux 3, Scientific Linux 3: gcc 3.2, 3.4.3, 4.0, 4.1.1

Mac OSX: gcc 3.4 and 4.0

Windows (Cygwin only): gcc 3.3.3

Available Binaries

Binaries built with this system can be obtained from the distribution download area.

These files are named according to the scheme.

slic-[version]-[platform]-[compiler]-[type].tar.gz

For instance, the file

slic-1_13_3-Linux-g++-bin.tar.gz

This binary is version 1.13.3 for Linux, compiled with g++. The type can be "bin" or "dist". The "bin" downloads contain only those files necessary to run the simulator while "dist" additionally includes the complete set of libraries used to build the binary.

Binary Installation

The process for installing a binary release for the aforementioned configuration is similar to this.

  1. Download the tarball using (for instance) the wget program. 
    wget http://www.lcsim.org/dist/slic/slic-1_13_3-Linux-g%2B%2B-bin.tar.gz
  2. Decompress it. 
    tar -zxvf slic-1_13_3-Linux-g++-bin.tar.gz
  3. Go into the SimDist directory and run the simulator. 
    cd SimDist
./scripts/slic.sh

Downloading and installing from a dist file is the easiest way to get SLIC up and running.

Building from Source

The Simulator Distribution can also be obtained and built from scratch. You may need to do this if the dist binaries do not work or if you need to make various customizations, such as changing the default Geant4 version.

  1. First, checkout the project from the SLAC cvs. 
    cvs -d :pserver:anonymous@cvs.freehep.org:/cvs/lcd co SimDist
  2. Go into the directory. 
    cd SimDist
  3. Configure the project. 
    ./configure
  4. Now, build the SimDist. 
    make

The binaries can be executed just as before.
