使用函数库定时中断中加的代码，编译不通过


void Timer0_ISR_Handler (void) interrupt TMR0_VECTOR                //进中断时已经清除标志
{
          run_flay=0;
                temp_value=0;
                ten_value=0;
       
        SEG_Fre();
       
                if(run_flay==1)
                {
                  ten_value++;                        //每隔1ms加1
      if(ten_value%10==0)temp_value++;
                }
}

这是什么问题？

这个和中断没有啥关系吧.
下面这一堆都是 extern,
extern bit run_flay;
extern u16 temp_value;
extern u16 ten_value;
其他地方有不带extern的声明吗,如果没有,肯定是这个错误.

这是警告问题不大
