linux内核测试LCD背景光测试程序问题 头疼呀

这几天一直在移植内核和文件系统，参考的是《天嵌科技出品-Linux移植之Step By Step_V4.5_20100605.》今天测试LCD背景光时出现个问题：
sh: 1: unknown operand
sh: 2: unknown operand

内打开控制台，但backlight: /lib/libgcc_s.so.1: version `GCC_3.5' not found (required by backlight)
backlight: /lib/libc.so.6: version `GLIBC_2.4' not found (required by backlight)，怎么解决？还有
/etc/rc.d/init.d/httpd: line 17: /sbin/boa: Permission denied  怎么解决，Line17的内容是esac  sbin目录里本来没有boa的，因为遇到一个提示sbin中缺少boa的问题，就以root身份建立一个boa，且权限是777

编绎过程贴上来

问题解决啦，文件系统中lib目录下缺少文件，参考天嵌《天嵌科技出品-Linux移植之Step By Step_V4.5_20100605.pdf》重新建立lib目录就行啦
