你好，我用得是TMS320C6748 DSP Development KIT, 用CCS5.4编程。用得是TI给的例子，也就是在C6748_StarterWare_1_20_03_03文件里的demoLedIf。
程序如下：
#include "gpio.h"
#include "soc_C6748.h"
#include "hw_psc_C6748.h"
#include "lcdkC6748.h"
#include "demoCfg.h"
static unsigned int ledState = 0;
void LedIfConfig(void)
{GPIOBank6Pin12PinMuxSetup();
GPIODirModeSet(SOC_GPIO_0_REGS, 109, GPIO_DIR_OUTPUT);}
void LedToggle(void)
{
if(ledState == 0) ledState = 1;
else ledState = 0;
GPIOPinWrite(SOC_GPIO_0_REGS, 109, ledState); }
void LedOff(void)
{ GPIOPinWrite(SOC_GPIO_0_REGS, 109, GPIO_PIN_HIGH); }
编译的时候就会出现
#10010 errors encountered during linking; "LED.out" not built 和 #10234-D unresolved symbols remain

请问这是什么问题呢？谢谢
