Couldn’t stat root device.
Makefile:42: recipe for target ‘Image’ failed
make: *** [Image] Error 1

##检查根设备是否存在
##这里我把赵炯老师的rootimage-0.11==>/dev/fd1
sudo dd if=rootimage-0.11 of=/dev/fd1

Boot sector 512 bytes.
Setup is 312 bytes.
Non-Gcc header of ‘system’
make: *** [Image] Error 1

解决办法：

将第一层主 Makefile 文件中的
LDFLAGS =-s -x -M 
修改为 
LDFLAGS =-m elf_i386 -Ttext 0 
Image: boot/bootsect boot/setup tools/system tools/build
tools/build boot/bootsect boot/setup tools/system $(ROOT_DEV) > Image
sync
修改为
Image: boot/bootsect boot/setup tools/system tools/build
objcopy -O binary -R .note -R .comment tools/system tools/kernel
tools/build boot/bootsect boot/setup tools/kernel $(ROOT_DEV) > Image
rm tools/kernel -f
sync
将 tools/ 文件中的
	if (((long *) buf)[5] != 0)
		  die("Non-GCC header of 'system'");
  这段代码注释掉
  //if (((long *) buf)[5] != 0)
  //  die("Non-GCC header of 'system'");
