XXX.cpp
#include "EM9000_DIO_EX.h"
#define P4_0 0x100 //GPIO8
#define P2_4 0x4000 //GPIO14
PIO_OutDisable(P4_0); //设置为输入使能
PIO_OutEnable(P2_4); //设置为输出使能
PIO_OutSet(P2_4); //GPIO14置高
。。。。。
PIO_OutClear(P2_4);
编译出现错误“error LNK2019: unresolved external symbol "int __cdecl PIO_OutClear(unsigned short)" (?PIO_OutClear@@YAHG@Z) referenced in function WinMain
error LNK2019: unresolved external symbol "int __cdecl PIO_OutSet(unsigned short)" (?PIO_OutSet@@YAHG@Z) referenced in function WinMain

error LNK2019: unresolved external symbol "int __cdecl PIO_OutDisable(unsigned short)" (?PIO_OutDisable@@YAHG@Z) referenced in function WinMain”
请问是什么原因？？？？？？？
