AliRoot
-------

Last update 18-March-1998 - Federico Carminati

This is the Version 3.00 of the ALICE simulation and reconstruction
software. This code has been released on March 18 after the ALICE Week. It
is intended to offer a general purpose framework for ALICE simulation and
reconstruction. The program should not be considered complete, and we are
relying on the feed-back from users to correct bugs and provide
improvements.

The simulation program is based on GEANT3.21. A special version of the
GEANT library and a mini-CERN Library are needed to run this code.

Installation
------------

Installation of the mini-CERN Library

- Take the file in /afs/cern.ch/alice/offline/AliCernlib.tar.gz and
unpack it into a directory:

$ cd <topdir>
$ gtar xvfz AliCernlib.tar.gz

- Edit the login file and assign the name of the directory where the file
has been unpacked to the variable ALITOP

setenv ALITOP <topdir>
setenv LD_LIBRARY_PATH $LD_LIBRARY_PATH\:$ALITOP/cern/new/lib\:. (on all systems)
setenv SHLIB_PATH $SHLIB_PATH\:$ALITOP/cern/new/lib (on hpux)

or

export ALITOP=<topdir>
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH\:$ALITOP/cern/new/lib\:. (on all systems)
export SHLIB_PATH=$SHLIB_PATH\:$ALITOP/cern/new/lib (on hpux)

- install the minicernlib:

cd $TOPDIR/cern/new/mkf
gmake -f Makefile.<mysystem>

where <mysystem> = linux_egcs or linux_gcc or alpha or solaris or
hpux. Some warning messages will appear during installation. At the end the
$TOPDIR/cern/new/lib file should contain:

$ ls -1 $TOPDIR/cern/new/lib
libgeant321.so
libgxint321.so
libminicern.so

(where .so is replaced by .sl in case of hpux).

- Take the file in /afs/cern.ch/alice/offline/AliRoot.tar.gz and
unpack it into a directory that you have created:

$ cd <wherever_you_want>
$ mkdir AliRoot
$ cd AliRoot
$ gtar xvfz ../AliRoot.tar.gz

- install the code

$ gmake -f Makefile.<mysystem> depend
$ gmake -f Makefile.<mysystem>

- run the code

$ aliroot
