Run demo on DM6437

I run demo Video_encdec on board of 6437 with 560V2USB and CCS5.1.
I have set include options.All *.h file can be found.
but when I build it, I encountered problem like:

 #10010 errors encountered during linking; "video_encdec_fio.out" not video_encdec_fio

#10234-D unresolved symbols remain video_encdec_fio

unresolved symbol _CERuntime_init, first referenced in ./main.obj video_encdec_fio
