lib/klib.o: In function `disp_int':
klib.c:(.text+0xe5): undefined reference to `__stack_chk_fail'
make: *** [kernel.bin] 错误 1

CFLAGS      = -I include/ -c -fno-builtin -fno-stack-protector

2.在Makefile的cflags后加入-nostdlib

CFLAGS      = -I include/ -c -fno-builtin -nostdlib

但是！%@……#&%*￥&%……#%@依旧错误....-_-#

问题不再Makefile，在于修改后，没有rm klib.o，make命令没有执行链接，所以还是出错！@#￥%%Z……&下面显示成功
