makefile

一个在uClinux下做的最简单的控制led的程序

CC = arm-elf-gcc
LD = arm-elf-ld
EXEC = leddemo
OBJS = leddemo.o

CFLAGS +=  
LDFLAGS += -Wl,-elf2flt  

all: $(EXEC)

$(EXEC): $(OBJS)
	$(CC) $(LDFLAGS) -o $@ $(OBJS) $(LDLIBS$(LDLIBS_$@))

	cp $(EXEC) ../uClinux-dist/romfs/bin
	genromfs -v -V "ROMdisk" -f ../uClinux-dist/images/romfs.img -d ../uClinux-dist/romfs
	$(LD) -r -o ../uClinux-dist/linux-2.4.x/romfs.out -b binary ../uClinux-dist/images/romfs.img

clean:
	-rm -f $(EXEC) *.elf *.gdb *.o

$(OBJS):
