标题[问题] undefined reference to...

想说要测试一下-O3的威能，就按照版上的文
将(1)src/Makefile.in 的 -g 改成 -O3
(2)Makefile 的 @strip bin/$(EXEC) 前的 # 拿掉
但是，先经过 make clean 再 make a 或 d 时，
会出现以下的error message:
Cleaning util...
make[1]: *** No rule to make target `dlist', needed by `.depend.mak'. Stop.

Removing libutil.a...

make: *** [main] Error 2
看起来像是有些library没有被include进来...
想了很久不知道怎麽fix这些error...
不知道有没有人有这个问题??
麻烦版上各位帮忙解惑XD 谢谢^^
