Introduction

This page will take you through getting the prerequisites of installing MAUS and ensuring that it's working. This will come in five phases:

  • Prerequisites - ensuring you have the basic tools required to compile code
  • Getting code - getting MAUS code (MAUS will attempt to handle dependencies)
  • Dependencies - installing third party dependencies that are required by MAUS
  • Building MAUS - ensuring everything compiles
  • Testing MAUS - running tests to ensure that you have a working copy of MAUS

Prerequisites

If you already have development tools and libraries installed like GCC, you can skip this section and continue to the next section... if you are unsure, continue.

To check if you have a compiler (which generally indicates that you have the rest) run at the command line the command gcc. You should see something like the following:

gcc: no input files

which means you can continue to the next section. If you see something like the following:

bash: gcc: command not found

then continue with this section.

To be able to compile MAUS, you will of course need a compiler. This should come with your machine and will require the person who runs the machine to install this. The following sections will deal with installing these prerequisites on various types of Linux.

Scientific linux

To install the tools required to build software on Scientific Linux, you must run the following commands:

sudo yum groupinstall "Development Tools" 
sudo yum groupinstall "Development Libraries" 

where the sudo command means that this is run as the root superuser. If you do not have this access, you must ask your system manager. If you are running Scientific Linux 4.8, then please also run:

sudo yum install xorg-x11-devel

Please return to the beginning of this section and repeat the test.

Debian or Ubuntu

To install the tools required to build software on Debian-based systems, you must run the following commands:

sudo apt-get install build-essentials

where the sudo command means that this is run as the root superuser. If you do not have this access, you must ask your system manager. Please return to the beginning of this section and repeat the test.

Other distribution

Please try using google to find out how to do it for your specific architecture. If you succeed, then please post those instruction here and continue with these instructions. If you fail, please email the user mailing list ().

Getting the code

If you are a user, it is recommended that you use a release since the repository is meant to be unstable since people are developing on it. If you are a developer, you should user the 'Bazaar' method. Regardless: there are three options for obtaining code.

Using a release (recommended for users)

Please click on the Files tab above and download the file maus-latest-release.tar.gz. Or you could choose to download a later release if you choose. Upon downloading the file (I'm going to assume you're using the latest, but just change the filename if you aren't), then run:

tar xvfz maus-latest-release.tar.gz

to extract the code. You should now have a directory called 'maus'.

Using a nightly release

Nightlies are packed nightly. This is not meant to be stable but is a way of obtaining the latest code without requiring the installation of Bazaar. Please run the following two commands if you want the nightly (if you are behind a firewall, download the this file and ignore the 'wget' step).

wget http://micewww.pp.rl.ac.uk/static_files/maus_nightly.tar.gz
tar xvfz maus_nightly.tar.gz

and you should now have a directory called 'maus'.

Bazaar repository (recommended for developers)

Bazaar is the program we use to maintain the repository. Please branch MAUS by running the following command.

bzr branch lp:maus

and you should now have a directory called 'maus'. If you get a 'command not found', you must install bazaar.

Dependencies

MAUS will try to help you by installing all of its dependencies for you. This is recommended that you allow rather than installing it on your own due to issues with the compiler flags of ROOT/Geant4 in most distributions (the issues is with not having the -fPIC argument to GCC for PIC).

Setup Environment

Please enter the MAUS directory that you just created in the previous section:

cd maus

You must first setup an environment within MAUS by running and ignoring complaints against python version:

./configure

which should return at the end:

SUCCESS: Whenever you want to use MAUS, you must 'source'
SUCCESS: the environmental variables file.  For Bourne-
SUCCESS: compatible shells like 'bash', run:
SUCCESS:
SUCCESS:      source env.sh
SUCCESS:
SUCCESS: and for C-compatible shells, run:
SUCCESS:
SUCCESS:      source env.csh
SUCCESS:
SUCCESS: which can be added to your respective shell's
SUCCESS: startup scripts.  Example: ~/.bashrc for 'bash'.

then obey the above "SUCCESS" instructions and run (replace env.sh with env.csh if you are using a C shell rather than something like bash):

source env.sh

which should then say:

SUCCESS: MAUS setup

You have now setup the MAUS environment. This will help MAUS know where it should install local copies of various dependencies. You can check that the output of the following two commands are the same:

echo $MAUS_ROOT_DIR
pwd
