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

DO NOT HAVE WHITESPACE IN DIRECTORY NAME: various third_party packages will break. This is beyond the scope of MAUS. See issue #306.

RAL-ONLY NOTE: please run export http_proxy=wwwcache.rl.ac.uk:8080 (or equivalent) to setup the RAL proxy

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/Redhat/Fedora

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" 
sudo yum install wget libX11-devel libXft-devel libXext-devel libXpm-devel libX11-devel

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.

Scientific Linux 4.8 only. 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-essential xorg-dev automake autoconf libtool scons zlibc

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.

RAL ONLY. For RAL people, you need to create a file called /etc/apt/apt.conf and fill it with:

ACQUIRE
{
http::proxy "http://wwwcache.rl.ac.uk:8080/";
}

When it installed then please return to the beginning of this section and repeat the test.

OpenSUSE

To install the required tools, you must run the following command:

sudo zypper install -t pattern devel_C_C++

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)

This is stable code since it is not under development. 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-latest-release'.

Bazaar repository (recommended for developers)

Unstable code, this is, since it's under development. The following command checks out the current source tree for MAUS that is under development. This code branch is meant to be unstable since it's being developed on. Please think before using this version.

Bazaar (bzr) is the program we use to maintain the repository. There is a MAUS-specific tutorial of using bzr here. Please branch MAUS. The code is hosted on launchpad under the MAUS project. To get the code, you must then run:

bzr branch lp:maus

and you should now have a directory called 'maus'. If you get a 'command not found', you must install bazaar. If you run into connectivity issues, you can check the bazaar server status here.

If you want to publish results based on MAUS, please use a release version of the code.

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: which can be added to your respective shell's
SUCCESS: startup scripts.  Example: ~/.bashrc for 'bash'.

then obey the above "SUCCESS" instructions and run

 source env.sh
. Please note that MAUS does not support c-shell or variants at present. If

echo The shell is $SHELL

contains any references to *csh then you will need to switch to, for example, bash, by typing

bash

Then do

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

Now it's time to build the dependencies of MAUS (ROOT, geant4, etc.). To let you know where are you in the process, it may be worthwhile running the following command:

scons

which should produce the following output:

scons: Reading SConscript files ...
**** Compiling in release mode...
Configuring...
Checking whether the C++ compiler worksyes
Checking for C++ library json... no
!! Can't find jsoncpp which is needed.
You may install it by running:
     MAUS_ROOT_DIR=~/MAUS/maus-latest-release ./third_party/bash/52jsoncpp.bash

where the build script couldn't find the 'jsoncpp' package, which is required to run MAUS.

It is now time to build the dependencies of MAUS (ROOT, Geant4, JsonCpp, etc.). Please run the following command from your MAUS_ROOT_DIR directory:

bash ${MAUS_ROOT_DIR}/third_party/build_all.bash

which will take an hour or two.

Building MAUS

You should now be able to run:

scons build

which should not return any errors. MAUS is now setup.

Testing MAUS

To test that MAUS works, please run the unit tests that are included.

scons build
bash run_tests.bash

which should not return any errors.

You are now ready to run MAUS!

Troubleshooting

  • I get an error about Python versions when I run ./configure: this is normal - you need to install third party libraries (including python 2.7) by doing
    bash ${MAUS_ROOT_DIR}/third_party/build_all.bash
