我原来的程序前面是这样的:
#include "STC15.H"
#include "intrins.h"
//#include "LQ12864.h"
#include "codetab.h"

#define On  1
#define Off 0

unsigned char Led_TimeCount ;
unsigned char Timer0_5Ms ;
unsigned char TIME_MM;
unsigned char TIME_SS;
unsigned char TIME_MM1;
unsigned char TIME_SS1 ;//预设时间值


sbit Led   = P3^5 ;                                          //用于秒闪烁
sbit Relay = P3^4 ;                                         //用于继电器吸合及释放
bit Timer0_1S_Flag ;
/*******************************************************************/
void Timer0_Init(void)        //5毫秒@12.000MHz
{
    AUXR |= 0x80;        //定时器时钟1T模式
    TMOD &= 0xF0;        //设置定时器模式( 16位自动重装 )
    TL0 = 0xA0;        //设置定时初值
    TH0 = 0x15;        //设置定时初值
    TF0 = 0;        //清除TF0标志
    TR0 = 1;        //定时器0开始计时
  ET0 = 1;
    EA  = 1;
        TIME_MM=12;
        TIME_SS=45;
}

void Timer0_Isr(void) interrupt 1 using 0
{
if ( ++Timer0_5Ms>= 200 )
   {
    Timer0_5Ms = 0 ;
    Timer0_1S_Flag  = 1 ;
    Led = On ;
    }
if ( Led )
         {
    Led_TimeCount++ ;
    if ( Led_TimeCount >=10 )  
       {
         Led_TimeCount = 0 ;
         Led = Off ;
       }
    }
}

void main (void)
{
unsigned int Second ;
unsigned char Hour ;
unsigned char Relay_TimeCount ;
Relay = Led = Off ;
Timer0_Init();
while(1)
{
   if ( Timer0_1S_Flag )
   {
     Timer0_1S_Flag = 0 ;
    if ( Relay )                     //如果继电器打开
     {
      Relay_TimeCount++ ;
      if ( Relay_TimeCount >= 3 )
       {  
        Relay_TimeCount = 0 ;
        Relay = Off ;
        }         
       }                                    
      if ( ++Second>=3600 )         //如果满1小时
       {
        Second = 0 ;
                                Hour++;
        if ( Hour >= 9 )
         {
          Hour = 0  ;
          Relay = On ;                                                            
         }
        }
     }
         
  }
}


把“#include"LQ12864.h"屏蔽掉,程序编译通过,无错误和警告;
把这句#include加上之后(LQ12864.h是一个OLED屏幕的驱动),就编译不过了


出现如下一串错误

照理这些都在开头定义了的,而且去掉LQ12864.H编译是能通过的,求原因
