error when build the project for the camera tracking

when i tried to build the project TwoColorTrackDemo-v2 that i got from the frc updates … i got that error

C:\Users\D777~1\AppData\Local\Temp\ ccppc: command not found
C:\WindRiver\workbench-3.0\x86-win32\bin\make.exe: *** [TwoColorTrackDemo/Debug/Objects/TwoColorTrackDemo/Target.o] Error 127
Build Failed in Project 'TwoColorTrackDemo' (Process Exit Value was 2):   2009-01-21 19:50:57   (Elapsed Time: 00:01)

please help me step by step how to solve this problem?

I got the same error ccpppc make not found.

I deleted every project in windriver.
I went into C:\windriver\workspace and make sure every folder was deleted. (except for .metadata)
I restarted windriver.
I loaded a new TwoColorTrackDemo example.

Boom, it builds without errors. Probably something intermediate… >.>
