Aduc702x.s Compiling error

: Error: L6218E: Undefined symbol DAbt_Handler (referred from aduc702x.o)
Can somebody help with this kind of error? How to resolve it? The thing is i didnt call "aduc702x.o" extension file. Does it relate to somewhere else?
PS: There is no error upon the compilation of my coding.
