按照附件txt文档中的步骤在ubuntu下LZMA patch for squashfs，make时出现如下信息，求高手解答

root@satfan-desktop:/Lzma# rm -rf squashfs3.2-r2/kernel-patches/linux-2.6.20/
root@satfan-desktop:/Lzma# ln -s linux-2.6.20/ squashfs3.2-r2/kernel-patches/linux-2.6.20

另外我手上有几个script/tool，在linux pc上运行不起来，烦请各位大大抽空看看，出错信息如下：
./undreamboxfs cnDB_DM500_Alpha.img ./temp
9472+1 records in
9472+1 records out
4850064 bytes (4.9 MB) copied, 0.111335 seconds, 43.6 MB/s
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

script中调用mkcramfs、mksquashfs、uncramfs，我自己查阅了一些资料，应该是要内核加入squashfs + lzma支持（img文件是squashfs + lzma），现在的问题是根本不能重编内核，郁闷啊~~~各位老大路过好心教教小弟，万分感谢！！！！

undreamboxfs、mkdreamboxfs运行有操作提示
