Hi maybe the following Makefile help you:


# -------------------------------------
INCLUDE=
FC=gfortran

FFLAG= -g -O3
LFLAG=

LIB_ALL=
#=====================================================================

#******************************
#******* O B J E C T S ********
#******************************
EXEC=yourExecutable

SCR_OBJECTS=\
object1.o\
object2.o\
.
.
.
object8.o



#******************************

%.o: %.f77
$(FC) $(FFLAG) -c $<

%.o: %.f
$(FC) $(FFLAG) -c $<

all: $(EXEC)

clean:
rm $(EXEC) $(SCR_OBJECTS) *.mod

$(EXEC): $(SCR_OBJECTS)
$(FC) $(LFLAG) -o $(EXEC) $(SCR_OBJECTS) $(LIB_ALL)

aaa sorry...
the clean line should be:

rm $(EXEC) $(SCR_OBJECTS) *.o

Archimedes80,thanks a lot.But there is another issue,I am using two data files for input,where to put them?I mean that they don't go to this directory.

Still have problem:
#
F77= f77
FLAGS= -O3

# Executable
SURFACE: SURFCE.O PHASE.O D2AS6INC.F
$(F77) $(FLAGS) -O SURFACE SURFCE.O PHASE.O

# Object files
SURFCE.O: SURFCE.F PHASE.F D2AS6INC.F
$(F77) $(FLAGS) -C SURFCE.F -O SURFCE.O
PHASE.O: PHASE.F
$(F77) $(FLAGS) -C PHASE.F -O PHASE.O

This is what I get:
f77 -O3 -C SURFCE.F -O SURFCE.O
surfce:
gcc: SURFCE.O: No such file or directory
f77 -O3 -C PHASE.F -O PHASE.O
phase:
gcc: PHASE.O: No such file or directory
f77 -O3 -O SURFACE SURFCE.O PHASE.O
gcc: SURFACE: No such file or directory
gcc: SURFCE.O: No such file or directory
gcc: PHASE.O: No such file or directory

At a guess these things are case sensitive and the output file needs to be -o instead of -O. -O is normally for optimization.

Similarly, the object file would normally be a .o instead of a .O
