sPHENIX discussion of software

[pinkenburg <pinkenburg AT bnl.gov>]

Hi folks,

with the advent of the ROOT_INCLUDE_PATH setting up your local install 
area for use is a bit more involved than it used to be. Under root5 you 
just had to tweak the LD_LIBRARY_PATH but with root6 it has to find the 
matching includes, otherwise you'll get really strange crashes.

There is a new script
/opt/sphenix/core/bin/setup_local.csh <your install area>
/opt/sphenix/core/bin/setup_local.sh for sPHENIX accounts

as arguments it needs your install area - if you have more than one (you 
should ask yourself why you would do this) you can add more than one 
install area in the argument list, the first one taking precedence. This 
script will tweak all needed environment variables, it'll prepend your 
install/bin to the path, install/lib to the LD_LIBRARY_PATH and some 
magic to straighten our the ROOT_INCLUDE_PATH (which sadly needs more 
than just prepending install/include). It will print out the new 
LD_LIBRARY_PATH and path so you can see what you are running with. The 
ROOT_INCLUDE_PATH tends to be humongous, printing it wouldn't be useful.

With the exception of the ROOT_INCLUDE_PATH, this script will not reset 
those paths, if you call it multiple times it will just prepend the new 
install area to the paths (and it will not strip duplicates). If you 
want to start from scratch, reset you environment first with

source /opt/sphenix/core/bin/sphenix_setup.csh -n
source /opt/sphenix/core/bin/sphenix_setup.sh -n for sPHENIX

and then source the setup_local script.

Chris
