calwrf编译问题！！！

研磨研磨

根据教程在CALWRF_V1.4下新建了一个Makefile文件（如下所示）
# makefile for calwrf.fbash: ./calwrf.exe: cannot execute binary file: Exec format error

PROGRAM = calwrf

FC = gfortran
FFLAGS = -fast -g -Mlfs

NETCDF = /usr/local/netcdf
LIBS = -lm -L${NETCDF}/lib -lnetcdf
INCL = -I${NETCDF}/include

OBJECTS = $(PROGRAM).o coordlib.o

$(PROGRAM): $(OBJECTS)
$(FC) $(FFLAGS) $(OBJECTS) $(LIBS) -o $@

coordlib.o : coordlib.for
$(FC) -c $(FFLAGS) $< -o $@

$(PROGRAM).o: $(PROGRAM).f
$(FC) $(FFLAGS) $(INCL) $(PROGRAM).f -c -o $(PROGRAM).o

clean:
rm *.o $(PROGRAM)
然后修改calwrf.inp中的数据后执行./calwrf.exe出现错误：
bash: ./calwrf.exe: cannot execute binary file: Exec format error
到底是哪的问题啊？？？？？？
