我在一个工程里添加了滚轮的代码，并且在左栏的Projece Explorer里添加了HAL_Wheel.h，HAL_Wheel.c，HAL_Menu.h，HAL_Menu.c 但是编译的时候出现了5个错误
#10010 errors encountered during linking; "TEST3.out" not built
#10056 symbol "__TI_int54" redefined: first defined in "./main.obj"; redefined in "./HAL_Wheel.obj"
#10234-D unresolved symbols remain
unresolved symbol >>, first referenced in Compilation
unresolved symbol Temprature, first referenced in ./main.obj
求教，应该怎么改？
