Compiling and Installing miniGhost

Procedure

Use PuTTY to log in to the server as the root user.
Run the following commands to decompress the miniGhost installation package:
```
unzip miniGhost-master.zip
```
Run the following command to switch to the directory generated after the package is decompressed:
```
cd /path/to/MINIGHOST/miniGhost-master/ref
```

Run the following commands to create a Makeflie file:

mv Makefile Makefile.bak
cp makefile.mpi.gnu Makefile

Run the following command to modify the Makeflie file:

Open Makefile.
```
vi Makeflie
```

Press i to enter the insert mode and modify the file as follows:

PROTOCOL = -D_MG_MPI
MPI_LOC = /path/TO/OPENMPI
MPI_INCLUDE = -I$(MPI_LOC)/include
# State precision: -D_REAL4 and/or -D_REAL8.
REAL_PRECISION = -D_MG_REAL8
# Integer precision: -D_INT4 and/or -D_INT8.
INT_PRECISION = -D_MG_INT4
# Compilers
FC=$(MPI_LOC)/bin/mpif90
CC=$(MPI_LOC)/bin/mpicc
CFLAGS = $(PROTOCOL) $(REAL_PRECISION) $(INT_PRECISION)
# C main calling Fortran subroutine:
CFLAGS += -Df2c_ -fsigned-char
CFLAGS += $(MPI_INCLUDE)
FFLAGS = $(PROTOCOL) $(REAL_PRECISION) $(INT_PRECISION)
# Optimization
OPT_F =-O3
FFLAGS += $(OPT_F)
#FFLAGS += $(MPI_INCLUDE)
# Free-form Fortran source code:
FFLAGS += -ffree-form -ffree-line-length-none
# Array bounds checking: (expensive!)
#FFLAGS += -fbounds-check
# Compile to include checkpointing capability.
FFLAGS += -D_MG_CHECKPT
NCPATH=
LNCDF=-L$(NCPATH)/lib
LD=$(CC)
LDFLAGS=$(CFLAGS) $(FFLAGS)  -L/path/to/GNU/gcc9.1/lib64/ -lgfortran -L/path/to/OPENMPI/openmpi-4.0.1-gcc9.1/lib -lmpi_mpifh
#LDFLAGS=$(CFLAGS) $(FFLAGS)
#LDFLAGS=$(FFLAGS)
LIBS=
include make_targets

Press Esc, type :wq!, and press Enter to save the file and exit.

Run the following command to perform compilation:
```
make
```
Parallel compilation (by using the make -j command) is not supported. Run the make command to perform compilation.
