The MEMPHYS package contains the simulation, some analysis programs and some .C ROOT scripts to produce plots from the MEMPHYS.root file produced by the MEMPHYS_sim program.
This package is pretty close in structure than a Geant4 example and can be built with cmake (MEMPHYS_sim only) beside the bush way. The visualization had been displaced in the MEMPHYS_vis package.
The below build instructions work on the file :
MEMPHYS-<version>.zip
found on the download area, or from a github clone.
///////////////////////////////////////////////////////////////////////////////////////////////////////
/// build by using the default geant4 found under inexlib/ourex: //////////////////////////////////////
///////////////////////////////////////////////////////////////////////////////////////////////////////
To build :
UNIX> cd MEMPHYS/mgr
UNIX> ./build
( UNIX> ./build -v # to see built files.)
( UNIX> ./build -x # for a full trace.)
(here UNIX is for Linux, macOS, Windows-10/cygwin, Windows-10/WSL)
If the GNU parallel application is known from your prompt, you can use
the "-parallel" option so that C and C++ file compilations are distributed
on your cores. This feature had been tested with success on macOS with a MacPorts
installation of the GNU parallel program and on centos7 with the GNU distribution.
This can clearly boosts a lot the build of the ourex/geant4 package.
You can build a binary zip distribution file with :
UNIX> ./build_distrib
At end, you should have a binary zip distribution file :
bin_<config>/distrib/MEMPHYS-<version>-<platform>.zip
If wanting to run from this build area :
UNIX> <in setenv_g4data[.sh,.csh] edit the g4data_home variable to point to the geant4 data directories>
UNIX> cd ../exa_run
UNIX> ../mgr/<bin_dir>/MEMPHYS_sim # it produces a MEMPHYS.root file.

To build the MEMPHYS_sim program against an already installed geant4 and by using cmake :
UNIX> cd <install_path>/MEMPHYS/MEMPHYS/cmake
UNIX> <read README for instructions to build and run>
(UNIX here is for Linux, macOS. Not tested or Windows-10/cygwin, Windows-10/WSL).

To build the MEMPHYS_sim program against an already installed geant4 by using the bush scripts :
UNIX> cd <install_path/MEMPHYS/MEMPHYS/mgr
sh> . <geant4_install_dir>/bin/geant4.sh
( csh> source <geant4_install_dir>/bin/geant4.csh )
UNIX> geant4-config # to test that this program is here.
Linux> <if needed source setup a gcc_[version].[sh,csh] file to have the correct g++>
( csh> source gcc_493.csh # on Lund iridium )
UNIX> ./build -sys_geant4
( UNIX> ./build -sys_geant4 -v # to see built files.)
( UNIX> ./build -sys_geant4 -x # for a full trace.)
You can build a binary zip distribution file with :
UNIX> ./build_distrib
At end, you should have a binary zip distribution file :
bin_<config>/distrib/MEMPHYS-<version>-<platform>.zip
If wanting to run from this build area :
UNIX> <in setenv_g4data[.sh,.csh] edit the g4data_home variable to point to the geant4 data directories>
UNIX> cd ../exa_run
UNIX> ../mgr/<bin_dir>/MEMPHYS_sim # it produces a MEMPHYS.root file.

To build (not mendatory) some X11 (or Windows) plotting program using a MEMPHYS.root data file :
UNIX> ./build_app_read_plot
To build an offscreen plotting program using a MEMPHYS.root data file :
UNIX> ./build_app_read_plot_offscreen
If having CERN-ROOT :
UNIX> <in cern_root_setup[.sh,.csh] edit root_home to point to your CERN-ROOT installation>
sh> . ./cern_root_setup.sh
( csh> source ./cern_root_setup.csh )
UNIX> ./build_app_read_plot_ROOT # do some plotting on a MEMPHYS.root data file
# by using CERN-ROOT plotting.
UNIX> ./build_app_geomt_ROOT # dump PMTs in a MEMPHYS.root data file, by using CERN-ROOT
# to read the file.
If these programs are built build_distrib script will include them in the distribution file.
