Installation of AliRoot on SUSE 11.X
A short guide on how to install AliRoot on a SUSE 11.X Linux system:

Prerequisites - Updated April 12, 2010
The first thing you need to do is apply for a NorduGrid certificate (ask Philippe Gros for help). Please cc me with the certificate request so I can verify you.
Then you need to register yourself with ALICE and get a computer account at CERN. See here.
Once you have got both the above you need to register your certificate with the ALICE VO by following step 3 and 4 here.
The software can be installed before you get the grid certificate but for any data analysis you need a valid grid certificate.
Packages - Updated April 12, 2010
You need to install the packages:
svn (subversion)
xorg11dev
automake (for recompiling the alien packages)
autoconf (for recompiling the alien packages)
libxml2-devel (for xml support in ROOT)
AliEn - Updated April 12, 2010
Before you set up any environment variables install alien. This can also be done before you obtain a grid certificate!
Execute the following commands in a terminal:
After you have installed alien go to the home dir and execute alien-token-init. Answer yes to recompile and make sure it finishes recompiling. Look in the error log if it fails and install the missing software packages if it fails. When alien have properly compiled you are ready for the next steps.cd mkdir software cd software wget http://alien.cern.ch/alien-installer chmod a+x alien-installer ./alien-installer -install-dir $HOME/software/alien
Environment variables - Updated February 1, 2011
The following environment variables are assuming that you use bash shell.
I installed everything in the $HOME/software directory.
Example of environment variables defined in my .cshrc file on musse:
export ROOTSYS=$HOME/software/root
if [ -z "$PATH" ]
then
export PATH=${ROOTSYS}/bin
else
# clean up path
export PATH=`echo $PATH | sed -r 's/(:|^)([^:]+)\/root([^:]+)(:|$)/:/g'`
export PATH=`echo $PATH | sed -r 's/(:|^)([^:]+)\/root([^:]+)(:|$)/:/g'`
export PATH=`echo $PATH | sed -r 's/(:|^)([^:]+)\/AliRoot([^:]+)(:|$)/:/g'`
export PATH=`echo $PATH | sed -r 's/(:|^)([^:]+)\/AliRoot([^:]+)(:|$)/:/g'`
export PATH=`echo $PATH | sed -r 's/(:|^)([^:]+)\/alien([^:]+)(:|$)/:/g'`
export PATH=`echo $PATH | sed -r 's/(:|^)([^:]+)\/alien([^:]+)(:|$)/:/g'`
export PATH=${ROOTSYS}/bin:$PATH
fi
if [ -z "$LD_LIBRARY_PATH" ]
then
export LD_LIBRARY_PATH=${ROOTSYS}/lib
else
# clean up path
export LD_LIBRARY_PATH=`echo $LD_LIBRARY_PATH | sed -r 's/(:|^)([^:]+)\/root([^:]+)(:|$)/:/g'`
export LD_LIBRARY_PATH=`echo $LD_LIBRARY_PATH | sed -r 's/(:|^)([^:]+)\/root([^:]+)(:|$)/:/g'`
export LD_LIBRARY_PATH=`echo $LD_LIBRARY_PATH | sed -r 's/(:|^)([^:]+)\/AliRoot([^:]+)(:|$)/:/g'`
export LD_LIBRARY_PATH=`echo $LD_LIBRARY_PATH | sed -r 's/(:|^)([^:]+)\/AliRoot([^:]+)(:|$)/:/g'`
export LD_LIBRARY_PATH=`echo $LD_LIBRARY_PATH | sed -r 's/(:|^)([^:]+)\/geant3([^:]+)(:|$)/:/g'`
export LD_LIBRARY_PATH=`echo $LD_LIBRARY_PATH | sed -r 's/(:|^)([^:]+)\/geant3([^:]+)(:|$)/:/g'`
export LD_LIBRARY_PATH=`echo $LD_LIBRARY_PATH | sed -r 's/(:|^)([^:]+)\/alien([^:]+)(:|$)/:/g'`
export LD_LIBRARY_PATH=`echo $LD_LIBRARY_PATH | sed -r 's/(:|^)([^:]+)\/alien([^:]+)(:|$)/:/g'`
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${ROOTSYS}/lib
fi
# ALIROOT variables
export ALICE=$HOME/software
export ALICE_ROOT=${ALICE}/AliRoot
export ALICE_TARGET=`root-config --arch`
export PATH=${ALICE_ROOT}/bin/tgt_${ALICE_TARGET}:$PATH
export
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${ALICE_ROOT}/lib/tgt_${ALICE_TARGET}
# GEANT 3
export PLATFORM=`root-config --arch`
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ALICE/geant3/lib/tgt_${ALICE_TARGET}
export ALIEN_ROOT=$ALICE/alien
export GSHELL_ROOT=$ALIEN_ROOT/api
export PATH=${GSHELL_ROOT}/bin:$PATH
alias rm='rm -i'
alias clean='rm -f *~ .*~ \#*\# *.{log,ilg,blg}'
alias realclean='clean; rm -f *.{toc,aux,idx,lof,lot,ind,glo,gls,dvi,bbl}'
Ps: All the sed's are to clean the PATH's because KDE takes a snapshot at the
beginning when I login so if I want to use different versions I have to kind
of reset the PATHs.
ROOT - Updated April 12, 2010
To get the version of ROOT matching the AliRoot version you want to use, check this web page.
Here is the script I used to install ROOT:
#!/bin/bash
cd ${ALICE}
svn co https://root.cern.ch/svn/root/tags/v5-26-00b root
cd root
./configure \
--with-f77=gfortran \
--with-pythia6-uscore=SINGLE \
--enable-roofit \
--enable-minuit2 \
--enable-xml \
--with-xml-incdir=${ALIEN_ROOT}/include/libxml2 \
--with-xml-libdir=${ALIEN_ROOT}/lib \
--with-ssl-incdir=${ALIEN_ROOT}/include \
--with-ssl-libdir=${ALIEN_ROOT}/alien/lib \
--with-alien-incdir=${ALIEN_ROOT}/api/include \
--with-alien-libdir=${ALIEN_ROOT}/api/lib \
--with-monalisa-libdir=${ALIEN_ROOT}/api/lib \
--with-monalisa-incdir=${ALIEN_ROOT}/api/include \
--with-xrootd-incdir=${ALIEN_ROOT}/api/include/xrootd \
--with-xrootd-libdir=${ALIEN_ROOT}/api/lib \
--enable-gsl-shared \
--disable-globus \
--build=debug
## You can check the options with make showbuild
make
Note that you don't have to do make install if you download and install root from the directory $HOME/alice.
GEANT 3 - Updated April 12, 2010
A script to install geant:
#!/bin/sh
cd ${ALICE}
svn co https://root.cern.ch/svn/geant3/tags/v1-11 geant3
cd geant3
make
AliRoot - Updated February 1, 2011
A script to install AliRoot (I am not sure the exports are needed. This was taken from an email by Federico Carmanati):
#!/bin/sh
cd ${ALICE}
svn co http://alisoft.cern.ch/AliRoot/trunk AliRoot
export CXX=`root-config --cxx`
export CC=`root-config --cc`
export F77=`root-config --f77`
export LD=`root-config --ld`
cd $ALICE_ROOT
mkdir `root-config --arch`
cd `root-config --arch`
cmake ../
make
make install
