[mpl_C5_s-mkpimage.bin] Error 2

when i use DS-5 to build example "\altera\16.0\embedded\examples\software\Altera-SoCFPGA-HardwareLib-MPL",i got a error :

14:21:45 **** Incremental Build of configuration Default for project Altera-SoCFPGA-HardwareLib-MPL ****

make: *** [mpl_C5_s-mkpimage.bin] Error 2

if i do not use ds-5,use cmd line to "make all",no error. who can tell me how to solve it?

Makefile's line 302 is "mkpimage --header-version 0 -o $@ $< $< $< $<"
