ecos on niosii

thanks u.

I returned to use the QII4.1sp2 ,now the posted errors had disappeared ,but now I found a new problem,which was after I builded a library for a project , if I wanted to use

"nios2configtool " to design another project , the NIOSII SDK warned me that "nios2configtool is running on. close down the other nios2configtool before starting this instance.If u are not running nios2configtool ,please delete the file :/../..../nios2_auto.cdl"

but when I deleted the file,the ecos did not run.

what's wrong with me ,how can I do for it .? Does the promble result from the last project ,the version of designing methods including niosII1.01, QII4.1sp2, win2000sp4 ,or

others.

thanks.
