出现这么多的错误，核心问题就是出现在miscutils/ubi_tools.c:63:26: error: mtd/ubi-user.h: No such file or directory这个上面，无法找到mtd/ubi-user.h头文件，查阅了相关资料后，原来这是一个Linux下新支持的UBI文件系统，需要手 工加入。从Linux2.6.29的include\mtd\ubi-user.h拷贝到busybox下的include\mtd下，如果 busybox下的include没有mtd文件夹，那就先建立一个mtd文件夹，然后复制了。这样做了之后，编译就OK了。出现下面的信息就说明编译成 功了。
