有很多小伙伴在使用XV6操作系统做相关的实验的时候经常会遇到报错Makefile:192: *** recipe commences before first target. Stop.，然后不知错所，这里提供一个可能报错这个情形，以及解决方法(目前仅用这种方法复习了这个报错，如果有其他情形报错一样，可以把Makefile文件发一份过来看一下)。

这里先上一下我这里复习这种报错时的Makefile文件的内容：

OBJS = \bio.o\console.o\exec.o\file.o\fs.o\ide.o\ioapic.o\kalloc.o\kbd.o\lapic.o\log.o\main.o\mp.o\picirq.o\pipe.o\proc.o\sleeplock.o\spinlock.o\string.o\swtch.o\syscall.o\sysfile.o\sysproc.o\trapasm.o\trap.o\uart.o\vectors.o\vm.o\# Cross-compiling (e.g., on Mac OS X)

解决方法：其实很简单，因为你在fs.img:少了一个空行，可能是修改的时候把这个空行不小心删除了，导致了他的错误。在图示位置将UPROGS结尾加一个空行即可。
