小弟初学STM8，在设置中断编译的时候出现
#error cpstm8 stm8_interrupt_vector.c:19(31) redeclared external USART1_RX_IRQn

求高手指点，纠结在这很久了

函数声明：
extern void USART1_RX_IRQn(void);

中断函数

@far @interrupt void USART1_RX_IRQn(void)
{
      u8 temp=0;
      if(USART_GetITStatus(USART1,USART_IT_RXNE)!=RESET)
      {
            USART_ClearITPendingBit (USART1,USART_IT_RXNE);
            USART_SendData8(USART1,USART_ReceiveData8(USART1));
            while(USART_GetFlagStatus(USART1,USART_FLAG_TXE)==RESET);

      }
      return;
}

向量表：
struct interrupt_vector const _vectab[] = {
      {0x82, (interrupt_handler_t)_stext}, /* reset */
      {0x82, NonHandledInterrupt}, /* trap  */
      {0x82, NonHandledInterrupt}, /* irq0  */
      {0x82, NonHandledInterrupt}, /* irq1  */
      {0x82, NonHandledInterrupt}, /* irq2  */
      {0x82, NonHandledInterrupt}, /* irq3  */
      {0x82, NonHandledInterrupt}, /* irq4  */
      {0x82, NonHandledInterrupt}, /* irq5  */
      {0x82, NonHandledInterrupt}, /* irq6  */

      {0x82, NonHandledInterrupt}, /* irq9  */
      {0x82, NonHandledInterrupt}, /* irq10 */
      {0x82, NonHandledInterrupt}, /* irq11 */
      {0x82, NonHandledInterrupt}, /* irq12 */
      {0x82, NonHandledInterrupt}, /* irq13 */
      {0x82, NonHandledInterrupt}, /* irq14 */
      {0x82, NonHandledInterrupt}, /* irq15 */
      {0x82, NonHandledInterrupt}, /* irq16 */
      {0x82, NonHandledInterrupt}, /* irq17 */
      {0x82, NonHandledInterrupt}, /* irq18 */
      {0x82, NonHandledInterrupt}, /* irq19 */
      {0x82, NonHandledInterrupt}, /* irq20 */
      {0x82, NonHandledInterrupt}, /* irq21 */
      {0x82, NonHandledInterrupt}, /* irq22 */
      {0x82, NonHandledInterrupt}, /* irq23 */
      {0x82, NonHandledInterrupt}, /* irq24 */
      {0x82, NonHandledInterrupt}, /* irq25 */
      {0x82, NonHandledInterrupt}, /* irq26 */
      {0x82, NonHandledInterrupt}, /* irq27 */
      {0x82, (interrupt_handler_t)USART1_RX_IRQn}, /* irq28 */
      {0x82, NonHandledInterrupt}, /* irq29 */
};

谢谢各位大神了
