我的makefile以前用都没问题 现在这个程序我要用到cos函数，需要用到数学库，应该是libm.a这个库吧，然后我把Makefile改了一下，把数学库包含了进来，然后就出现了那么多错误错误如下：

Makefile如下：
objs := crt0.o init.o nand.o leds.o
LIBPATH=-lgcc -L/work/tools/gcc-3.4.5-glibc-2.3.6/lib/gcc/arm-linux/3.4.5/
LIBPATH1=-lm -L/work/tools/gcc-3.4.5-glibc-2.3.6/arm-linux/lib/
leds.bin: $(objs)
arm-linux-ld -Tleds.lds -o leds_elf $^ ${LIBPATH} ${LIBPATH1}
arm-linux-objcopy -O binary -S leds_elf $@
arm-linux-objdump -D -m arm leds_elf > leds.dis
%.o:%.c
arm-linux-gcc -Wall -O2 -c -o $@ $<
%.o:%.S
arm-linux-gcc -Wall -O2 -c -o $@ $<
clean:
rm -f leds.bin leds_elf leds.dis *.o
我的链接脚本如下：
SECTIONS {
firtst 0x00000000 : { crt0.o init.o nand.o}
second 0x30000000 : AT(4096) { leds.o }
}
