C6745的中断向量表没有链接上,出现undefined symbol 在./INTC.obj

#include "main.h"

__cregister volatile unsigned int AMR;

__cregister volatile unsigned int ICR;

void INTC_Init(void)

{

// Map EDMA3_CC0_INT1/GPIO_B4INT System interrupts to DSP INT4/5

INTC_INTMUX1 = (8 << 0) | (54 << 8);

// Assign the address of the IST to the IST pointer

ISTP = (unsigned int)intcVectorTable;

// Clear all CPU maskable interrupts

ICR = 0xFFF0;

// Enable NMI, INT4-INT5 interrupts

IER = (1 << 1) | (1 << 4) | (1 << 5);

}

interrupt void GPIO_B4INT4_isr (void)

{

printf("\tInitiating transfer...\n");

}

interrupt void EDMA3_CC0_INT1_isr (void)

{

uint32_t regIPR, IxBitMask, IxCounter;

while(EDMA3_IPR != 0)

{

// Read Interrupt Pending Register

regIPR = EDMA3_IPR;

// Loop for Set Interrupt Pending Bit

for(IxCounter = 0; IxCounter < 32; IxCounter++)

{

IxBitMask = 1 << IxCounter;

if(regIPR & IxBitMask)

{

// Exit Example on Correct Interrupt

if(IxCounter == 28)

// Clear Pending Interrupt

EDMA3_IPR = IxBitMask;

break;

}

}

}

}

在main.h中已经定义了extern void intcVectorTable (void);

为什么编译的时候还会出现下面这个问题
