| 9 | How to build |
|---|
| 10 | ============ |
|---|
| 11 | |
|---|
| 12 | 1. Check "G4MPI.gmk" for yor MPI configuration: |
|---|
| 13 | |
|---|
| 14 | * Set "G4MPIROOT", which is the root path to your MPI library. |
|---|
| 15 | * Redifine CXX as (wrapped) MPI C++ compiler. |
|---|
| 16 | * Specify additional include paths and compiler flags to "CPPFLAGS". |
|---|
| 17 | |
|---|
| 18 | Sample makefiles for (OpnMPI, LAM, MPICH2) are also presented. |
|---|
| 19 | An example of "G4MPI.gmk": |
|---|
| 20 | |
|---|
| 21 | # =========================================================== |
|---|
| 22 | # Makefile for building G4MPI (OpenMPI) |
|---|
| 23 | # =========================================================== |
|---|
| 24 | |
|---|
| 25 | ifndef G4MPIROOT |
|---|
| 26 | G4MPIROOT = /opt/ompi |
|---|
| 27 | endif |
|---|
| 28 | |
|---|
| 29 | # additional flags |
|---|
| 30 | CXX := mpic++ |
|---|
| 31 | CXXFLAGS := $(subst -Wall, , $(CXXFLAGS)) |
|---|
| 32 | CPPFLAGS += -I$(G4MPIROOT)/include -I$(G4MPIROOT)/include/openmpi |
|---|
| 33 | |
|---|
| 34 | |
|---|
| 35 | 2. Build the library |
|---|
| 36 | |
|---|
| 37 | # make |
|---|
| 38 | # make includes |
|---|
| 39 | |
|---|
| 40 | The library (libG4UImpi) will be created in $G4LIB, |
|---|
| 41 | and header files will be installed into $G4INCLUDE. |
|---|
