How to build
============
1. Check "G4MPI.gmk" for yor MPI configuration:
* Set "G4MPIROOT", which is the root path to your MPI library.
* Redifine CXX as (wrapped) MPI C++ compiler.
* Specify additional include paths and compiler flags to "CPPFLAGS".
Sample makefiles for (LAM, MPICH2, OpenMPI) are also presented.
An example of "G4MPI.gmk":
# ===========================================================
# Makefile for building G4MPI (LAM)
# ===========================================================
ifndef G4MPIROOT
G4MPIROOT = /opt/lam
endif
# additional flags
CXX := mpic++
CPPFLAGS += -I$(G4MPIROOT)/include
2. Build the library
# make
# make includes
The library (libG4UImpi) will be created in $G4LIB,
and header files will be installed into $G4INCLUDE.
