Simulator Distribution

Overview

The Geant4-based simulator SLIC (http:/www.lcsim.org/software/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.

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

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.
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 Scratch

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:jeremy@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.

Known Working Configurations

This is a list of known working configurations.

*Red Hat Enterprise Linux 3, gcc 3.2.3

*Mac OSX, gcc 3.4, 4.0

*Windows (Cygwin), gcc 3.3.3

If you do not see your operating system or compiler listed here, then please contact me and I can work on making SimDist compatible with it. Bugs should be reported to the same.
