C++ Catastrophic error in libs compiling

[whatabouteve]

1.we use windriver so the program automatically compiles when you hit build project.

2. windriver always returns an error message

3.this is a different computer that we don't program on.

the error is as i can best descride it.

in the build of "project file location/AnalogChannel.cpp" line 7 catastrophic error (etoa:4005): could not open source file "CAnalogChannel.h"

Note: this was after deleting the accelerometer error. this is the second program in the file list after accelerometer. The same thing occured with CAccelerometer.cpp

thank you
