|

In order to use the Anaphe implementation of the AIDA 2.2 interfaces,
|
||||
prepare some environment variables by source-ing one of the following
|
||||
startup scripts (depending on your compiler version):
|
||||
In order to use the Anaphe implementation of the AIDA 3.0 interfaces,
|
||||
the 'aida-config' command (which is used in the GNUmakefile) is
|
||||
available at:
|
||||
/afs/cern.ch/sw/lhcxx/share/LHCXX/latest/scripts/aida-config
|
||||
|
||||
# gcc-2.95.2
|
||||
source $LHCXXTOP/share/LHCXX/4.0.1/install/sharedstart.sh or .csh
|
||||
In order to run the executable, you need to source the following
|
||||
script (once):
|
||||
$HOME/bin/setupAnaphe.csh (or $HOME/bin/setupAnaphe)
|
||||
|
||||
# egcs_1.1.2 (aka gcc 2.91.66)
|
||||
source $LHCXXTOP/share/LHCXX/4.0.1-sec/install/sharedstart.sh or .csh
|
||||
|
||||
At CERN, $LHCXXTOP is /afs/cern.ch/sw/lhcxx, you may want to use a
|
||||
more recent release, check http:/cern.ch/anaphe for more information.
|
||||
|
||||
After this, you will have access to the 'aida-config' command which
|
||||
is used in the GNUmakefile.
|
||||
At cern 'setupAnaphe' is available at:
|
||||
/afs/cern.ch/sw/lhcxx/share/LHCXX/latest/scripts/setupAnaphe.csh
