Have you installed the WPILib update (
from FIRST Forge)? If not, you don't have the WPILib headers installed
If you have installed that, then how did you create your project? Was it as a new "vxWorks Downloadable Kernel Module Project", or did you take one of the samples and rename it? If the former, then the project doesn't have the proper include directories set, and thus can't find the files.
All of the header files can be found in C:\WindRiver\vxworks-6.3\target\h\WPILib
