请教关于wince6的错误“Could not find file rsaenh.dll”
当我执行：“rebuild and clean sysgen”的时候：
出现如下错误：

我在上次编译成功和这次编译失败之间，只做了删除驱动的操作，只修改了驱动中的dir 和platform.bib、 platform.reg 
请问这个错误是什么原因造成的？？
谢谢

------解决方案--------------------
这么巧，我昨天也遇到这个问题，之前一直都是可以的，我再试一下。

你看看你的release目录下面的ce.bib到底改到了没有，如果没有改到就clean了再拷贝一下


请问：
“如果没有改到就clean了再拷贝一下”
这句话怎么理解？？
ce.bib在哪能拷贝？？
