How to compile QSNO (tricks)
============================

First get the code you need (tar files for LINUX):

See: 

/data/data002/alainb/linux/tar

1)

Set you environment variables. Example on a linux node your "setup_qsno.csh"
shall look like:

setenv MAKE make
setenv SNO_SNOMAN_VER 4_0196
setenv CERNDIR /local/cern/pro/lib
setenv CDSERV /data/data001/hepdb/cdsno
setenv SNODB_ROOT /data/data001/hepdb/cdsno
setenv SNODB_VER 4_00
setenv SNO_ROOT /local
setenv SNO_TOOLS $SNO_ROOT/snoman/tools/exe
setenv ROOTSYS /local/root
setenv QSNO_ROOT /local/qsno
setenv PATH {$QSNO_ROOT}/bin:{$QSNO_ROOT}/scripts:{$QSNO_ROOT}/parameters:{$ROOTSYS}/bin:{$PATH}
setenv QPHYSICS {$QSNO_ROOT}/qphysics
if ({$?LD_LIBRARY_PATH}) then
setenv LD_LIBRARY_PATH {$QSNO_ROOT}/lib:{$ROOTSYS}/lib:{$LD_LIBRARY_PATH}
else
setenv LD_LIBRARY_PATH {$QSNO_ROOT}/lib:{$ROOTSYS}/lib
endif

2) 

ROOT must be installed on your system.

3)

To compile QSNO just type "make" in the QSNO_ROOT directory.
It will produce:

reflecttime
tdiff
avgeom
qpath
snomanpp
root

Now when you will fire the graphical analysis package ROOT you will
be able to invoke QSNO classes. Make sure $ROOTSYS point to the
directory created by "gmake" when ROOT was installed. QSNO needs
for example $ROOTSYS/config/Makefile.

If you'd like to get the full SNO compile SNOMAN first. 
The file "$SNO_TOOLS/get_cpp_code_libd.scr" and 
"$QSNO_ROOT/config/add_external_librairies.scr"
are the two main routines to get QSNO in SNOMAN.

3)

On moosehead (solaris) you need to do a little bit more.
You must add /opt/SUNWspro/bin to your PATH to get f77, 
CC, etc...

On moosehead installation will crash before completion. No panic 
there is a fix. The script "add_external_libraries.scr" will be 
created and you will need to add manually to the *end* of 
NO_EXTERNAL_LIBRARIES "-lCrun -lCstd".

See /home/alainb/solaris/qsno/config for example.
