"No rule to make target" error

[Tungsten]

Hello,
We are having severe errors with Windriver. Whenever we compile a program, regardless of whether or not it has any errors in it, the following error message appears:

C:\WindRiver\vxworks-6.3\host\x86-win32\bin\make.exe: ***No rule to make target 'b'. Stop.
Build Failed in Project 'AxisCamera' (Process Exit Value was 2): 2012-01-23 17:32:33 (Elapsed Time 00:00)

We have tried putting the same code on a different computer, and it builds perfectly fine. We suspect that something is wrong with the directories, but we don't know exactly what is wrong and how to fix it.
