STM8s使用STVD编译时出现的奇葩问题,哪位大神解答一下

问题如标题所述,问题出现在stm8_interrupt_vector.c中,将相同的代码与变量移到main.c中则没有问题。太奇怪了!
出现的错误提示如下:
#error clnk Debug\123.lkf:1 symbol c_idiv not defined (Debug\stm8_interrupt_vector.o )
#error clnk Debug\123.lkf:1 symbol c_sdivx not defined (Debug\stm8_interrupt_vector.o )
The command: "clnk -m Debug\123.map -l"D:\Program Files\Cosmic\Lib" -o Debug\123.sm8 Debug\123.lkf " has failed, the returned value is: 1
exit code=1.
错误提示貌似和除法命令有关,所以我就把代码中的除法换成了加法,结果居然编译通过!好奇怪。本人初学者。
stm8_interrupt_vector.c文件中的代码如下:
#include "stm8s903k3.h"
unsigned char rx_buffer[21];//接收缓存
unsigned char RSSI_value;//RSSI寄存器中的值
signed int RSSI_dBm = 0;//接收信号的强度
signed int RSSI_sum = 0; //3次的RSSI_dBm和
signed int RSSI_ave;//3次的RSSI_dBm的平均值
signed int RSSI_buffer[3];//最近三次的RSSI_dBm值

我也遇到类似问题,就会定义不了
