Dear Craig Dedo
Actually i want to use it on Linux (ubuntu 8.10) and the method
suggested by Daniel can be used on any operating system (by adjusting
the MKDIR variable in the makefile. this is the final one that works
for me:
PROG =    a.out
SRCDIR = sources
OBJDIR = objects
MKDIR= mkdir
OBJS =    $(OBJDIR)/main.o $(OBJDIR)/setarray.o $(OBJDIR)/vardef.o
LIBS =
FC = gfortran
FFLAGS = -O
F90 = gfortran
F90FLAGS = -O
LDFLAGS = -s
all: $(PROG)
$(PROG): $(OBJS)
	$(F90) $(LDFLAGS) -o $@ $(OBJS) $(LIBS)
clean:
	rm -f $(PROG) $(OBJS) *.mod
.SUFFIXES: $(SUFFIXES) .f90
$(OBJDIR)/%.o : $(SRCDIR)/%.f90
	test -d $(OBJDIR) || $(MKDIR) $(OBJDIR)
	$(F90) $(F90FLAGS) -c $< -o $@

$(OBJDIR)/main.o: $(OBJDIR)/vardef.o
$(OBJDIR)/setarray.o: $(OBJDIR)/vardef.o

Regards,
Hadian
