Appendix: Makefile

What is a Makefile

A Makefile is a file that automatically compiles your program. When there are many different files (modules) and that these files call each other, it might be helpful to automate the process of generating the program. The structure of a Makefile is the following
# Start of the Makefile
# Defining variables
FC = ifort #gfortran # Fortran Compiler
FFLAGS = -openmp #-fopenmp # Fortran Flags
LFLAGS = # Library Flags
OBJECTS = main.o params.o nrtype.o nrutil.o grid.o preference.o demographics.o labor.o gridtax.o evaluate.o output.o tauchenhussey.o newton.o euler_eqn.o household.o resid.o taxfn.o distribution.o zbrent.o
MODULES = nrtype.mod nrutil.mod params.mod
.PHONY: clean
# Makefile
exec : $(OBJECTS)
$(FC) $(FFLAGS) -o replication_parallel $(OBJECTS)
nrtype.o : nrtype.f90
$(FC) -c $(FFLAGS) $<
nrutil.o : nrtype.mod nrutil.f90
$(FC) -c $(FFLAGS) nrutil.f90
params.o : nrtype.mod params.f90
$(FC) -c $(FFLAGS) params.f90
# below: to replace with: %.o : params.mod %.f90
# $(FC) -c $(FFLAGS) %.f90 ??
# not sure it works
main.o : params.mod nrtype.mod main.f90
$(FC) -c $(FFLAGS) main.f90
grid.o : params.mod grid.f90
$(FC) -c $(FFLAGS) grid.f90

$(FC) -c $(FFLAGS) resid.f90
taxfn.o : params.mod taxfn.f90
$(FC) -c $(FFLAGS) taxfn.f90
distribution.o : params.mod distribution.f90
$(FC) -c $(FFLAGS) distribution.f90
# this one is different
zbrent.o : nrtype.mod nrutil.mod zbrent.f90
$(FC) -c $(FFLAGS) zbrent.f90
nrtype.mod : nrtype.f90
$(FC) -c $(FFLAGS) $<
nrutil.mod : nrutil.f90
$(FC) -c $(FFLAGS) $<
params.mod : params.f90
$(FC) -c $(FFLAGS) $<
clean:
rm -f $(OBJECTS) $(MODULES)
#END OF MAKEFILE

How to use a Makefile

use the following command
make -f Makefile
You can also only run the clean part of the Makefile by
make clean -f Makefile
