在VDSP++5.0的工程里文件夹里放入test.**件，在工程的某C文件里include"test.h" ,编译通过，然后把test.**件改名为test2.h,C文件里的include"test.h"改为include"test2.h" ,编译通不过了，出现了：

----------------Configuration: 21479 AD1939 C Sampled-Based Talkthru 48 or 96 kHz - Debug----------------

C:\Program Files\Analog Devices\VisualDSP 5.0\gmake-378: *** No rule to make target `test.h', needed by `Debug/process_audio.doj'.  Stop.

No valid command(s) to build.

Build was unsuccessful.

请教是什么原因及怎么解决？谢谢！
