求助undefined reference to `usbInterruptIsReady'编译错误
在man函数里
if(usbInterruptIsReady()){
         /* called after every poll of the interrupt endpoint */
         advanceCircleByFixedAngle();
         DBG1(0x03, 0, 0); /* debug output: interrupt report prepared */
         usbSetInterrupt((void *)&reportBuffer, sizeof(reportBuffer));
      }

在头文件<usbdrv.h>里有

#if USB_CFG_HAVE_INTRIN_ENDPOINT
      USB_PUBLIC void usbSetInterrupt(uchar *data, uchar len);//////////////////////////////
   #define usbInterruptIsReady() (usbTxLen1 & 0x10)//////////////////////////////////////////
#endif /* USB_CFG_HAVE_INTRIN_ENDPOINT */

编译时出错
undefined reference to `usbInterruptIsReady'
undefined reference to `usbSetInterrupt'
请问是哪里的问题
