Packages - Updated June 28, 2007

You need to install the packages:
cvs
xorg11dev
compat-g77 (for g77, but note that you need a version with cc1, see below)
automake (for recompiling the alien packages)
autoconf (for recompiling the alien packages)
libxml2-devel (for xml support in ROOT)

If you don't have cc1 in your compat-g77 you can look here.

Environment variables - Updated September 9, 2007

I installed everything in the $HOME/alice directory.
Example of environment variables defined in my .cshrc file on musse: 

if( -t 1 ) then
    echo 'Using software in august2007'
endif

# ROOT variables
#setenv ROOTSYS /home/alicesoft/alice/root
setenv ROOTSYS /home/alicesoft/august2007/root
setenv PATH ${ROOTSYS}/bin:`echo $PATH | sed -r 's/(:|^)([^:]+)\/root([^:]+)(:|$)/:/g'`
if ($?LD_LIBRARY_PATH) then
    setenv LD_LIBRARY_PATH ${ROOTSYS}/lib:`echo $LD_LIBRARY_PATH | sed -r 's/(:|^)([^:]+)\/root([^:]+)(:|$)/:/g'`
else
    setenv LD_LIBRARY_PATH ${ROOTSYS}/lib
endif

# ALIROOT variables
#setenv ALICE /home/alicesoft/alice
setenv ALICE /home/alicesoft/august2007
setenv ALICE_ROOT ${ALICE}/AliRoot
setenv ALICE_TARGET linuxx8664gcc
setenv PATH ${ALICE_ROOT}/bin/tgt_${ALICE_TARGET}:`echo $PATH | sed -r 's/(:|^)([^:]+)\/AliRoot([^:]+)(:|$)/:/g'`
setenv LD_LIBRARY_PATH ${ALICE_ROOT}/lib/tgt_${ALICE_TARGET}:`echo $LD_LIBRARY_PATH | sed -r 's/(:|^)([^:]+)\/AliRoot([^:]+)(:|$)/:/g'`
# GEANT 3
setenv PLATFORM linuxx8664gcc
setenv LD_LIBRARY_PATH ${ALICE}/geant3/lib/tgt_${ALICE_TARGET}:`echo $LD_LIBRARY_PATH | sed -r 's/(:|^)([^:]+)\/geant3([^:]+)(:|$)/:/g'`

# ALIEN
setenv alien_API_USER "pchristi"
setenv alien_HOME "/alice/cern.ch/user/p/pchristi/"

setenv ALIEN_ROOT $ALICE/alien
setenv GSHELL_ROOT $ALIEN_ROOT/api
setenv GSHELL_GCC `which gcc`
setenv PATH ${GSHELL_ROOT}/bin:${ALIEN_ROOT}/bin:${ALIEN_ROOT}/globus/bin:${PATH}
setenv LD_LIBRARY_PATH ${ALIEN_ROOT}/globus/lib:${GSHELL_ROOT}/lib:${LD_LIBRARY_PATH}

alias rm 'rm -i'
alias clean   'rm -f *~ .*~ \#*\# *.{log,ilg,blg}'
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.

AliEn - Updated June 28, 2007

Execute the following commnands in a terminal:

wget http://alien.cern.ch/alien-installer
chmod a+x alien-installer
./alien-installer
- Version 2.13
- I choose i686-pc-linux
- You need 3 packages: gshell, client, and xrootd
Then you have to recompile some of the packages: 
cd $ALIEN_ROOT/api/src/
./recompile.xrootd
./recompile.gapi

ROOT - Updated June 28, 2007

To get the version of ROOT matching the AliRoot version you want to use, check this web page.

Check that you have: 

/usr/lib/libGLU.so
This is Open GL which comes in the package called mesa. I only had libGLU.so.1, so I made the soft link by hand: 
 
cd /usr/lib
ln -s libGLU.so.1 libGLU.so

Here is the script I used to install ROOT: 

#!/bin/sh
##
##   TO REMOVE AN OLD INSTALLATION
#    cd root
#    make uninstall
#    cd ..
#    rm -fr root
##
##   TO CHECK OUT A NEW VERSION
##   (password is cvs)
    cvs -d :pserver:cvs@root.cern.ch:/user/cvs login
    cvs -d :pserver:cvs@root.cern.ch:/user/cvs -z3 export -r v5-15-08 root
##   to check out the development version
##    cvs -d :pserver:cvs@root.cern.ch:/user/cvs -z3 checkout root
##   if you use gfortran and on 64bits
##   edit config/makefile.linuxxx8664gcc to include the gfortran from
##   config/makefile.linux
## For xml you need libxml2-devel pacakge
##
##  TO CONFIGURE THE VERSION
    cd root
    ./configure \
        --with-pythia6-uscore=SINGLE \
        --disable-cern  \
        --disable-clarens \
        --enable-xml \
        --enable-mathmore \
        --enable-mathcore \
        --enable-asimage \
        --enable-minuit2 \
        --enable-alien \
        --with-xrootd=${ALIEN_ROOT}/api \
        --with-alien-incdir=${ALIEN_ROOT}/api/include \
        --with-alien-libdir=${ALIEN_ROOT}/api/lib  \
        --with-shift-libdir=/usr/local/lib \
        --disable-castor
## You can check the options with make showbuild
##
##  TO COMPILE THE FILE
    make clean-netx
    make clean-xrootd
    rm -rf lib/libXrd*
    make
    make install
    make map

Note that you don't have to do make install if you download and install root from the directory $HOME/alice.

GEANT - Updated September 6, 2007

A script to install geant: 

#!/bin/sh
cd ${HOME}/alice
cvs -d :pserver:cvs@root.cern.ch:/user/cvs co -r v1-8 geant3
cd geant3
make

AliRoot - Updated September 6, 2007

A script to install AliRoot: 

#!/bin/sh
cd ${HOME}/alice
cvs -d:pserver:cvs@alisoft.cern.ch:/soft/cvsroot login
cvs -q -z2 -d:pserver:cvs@alisoft.cern.ch:/soft/cvsroot co AliRoot
cd AliRoot
