Quick installation on Linux (might work elsewhere)
         ==================================================

NOTE: tag names and CLHEP versions, etc., will change.  These are
representative and apply on 2nd August 2001.

NOTE: as for csh.  For sh, ksh, bash, replace setenv by export and put
'=' between name and value, e.g., export G4=<your G4 working
directory>.

1)   setenv G4 <your G4 working directory>
     setenv SCRATCH <your-work-directory>  (for binaries)

2)   cd $G4
     cvs co -r geant4-03-02-ref-02 geant4

3) Needs CLHEP1.7: go to Geant4 Web Page, Download, CLHEP version 1.6
   (sic), CLHEP, "LINUX V1.7 using egcs 1.1.2" and untar into, say,
   G4/CLHEP1.7/.  (egcs 1.1.2 is the default compiler on Noric.)
     cd $G4
     mkdir CLHEP1.7
     cd CLHEP1.7
     tar xzf clhep-1.7.0.0-egcs-1.1.2.tar.gz

4) Optionally, update to later subtags:
     cd $G4/geant4/source/visualization
     cvs update -d -P -r vis-V03-02-12
     cd $G4/geant4/graphics_reps
     cvs update -d -P -r greps-V03-02-03
     cd $G4/geant4/intercoms
     cvs update -d -P -r intercoms-V03-02-04

5)   setenv G4INSTALL $G4/geant4
     setenv G4BIN $SCRATCH/bin
     setenv G4LIB $SCRATCH/lib
     setenv G4TMP $SCRATCH/tmp
     setenv G4SYSTEM Linux-g++
     setenv G4LEVELGAMMADATA $G4INSTALL/data/PhotonEvaporation
     setenv CLHEP_BASE_DIR $G4/CLHEP1.7
     setenv LD_LIBRARY_PATH $LD_LIBRARY_PATH:$CLHEP_BASE_DIR/lib

5) VIS and UI variables (the BUILD variables are for installers, the
   USE for users - you are both!):
     setenv G4VIS_BUILD_OPENGLX_DRIVER 1
     setenv G4VIS_USE_OPENGLX 1
     setenv G4UI_BUILD_TERMINAL_SESSION 1   (*)
     setenv G4UI_USE_TERMINAL 1
     setenv OGLHOME /usr/X11                (Might not be necessary)

6) If you're more adventurous, have motif or lesstif...
     setenv G4VIS_BUILD_OPENGLXM_DRIVER 1
     setenv G4VIS_USE_OPENGLXM 1
     setenv G4UI_BUILD_XM_SESSION 1
     setenv G4UI_USE_XM 1

7) ...or want to try GAG (Japanese GUI):
     setenv G4UI_BUILD_GAG_SESSION 1       (*)
     setenv G4UI_USE_GAG 1

8) Optionally:
     setenv G4DEBUG 1

9)   cd $G4INSTALL/source
     gmake >& gmake.log &

10)  cd $G4INSTALL/examples/novice/N03
     gmake >& gmake.log &
