build an eCos library error

Thank you, nigelatta!

You are Right!

My "--cpu=" parameter was not correct.

But i meet a new error. When i open an exist file ,some error occur.

C:\altera\ecos_demo\lib\demo.ecc: error

C:\altera\ecos_demo\lib\demo.ecc: error

C:\altera\ecos_demo\lib\demo.ecc: error

Is it meaning c:\altera\kits\...\ecos\package\devs\alt\mac is missing ? or not ?
