在CCSv5.5中编译时出现以下问题

这是console窗口中的

这是我把主程序改了之后才出现的，一开始没有问题

Hi，你使用了没有被定义的_InitGpio？正如console内容的提示。

确实有可能是，我重新定义了下，并重新编译中，正在建立工程。

void InitEPwm1(void);void InitEPwm2(void);void InitEPwm1Gpio(void);void InitEPwm2Gpio(void);void main(void){ InitSysCtrl();  InitGpio();  InitEPwm1Gpio(); InitEPwm2Gpio(); InitEPwm1(); InitEPwm2();

我把红色部分去掉，编译就没有错误了。请问Seven Han,假如我还是希望它在程序中的话，应该怎么去定义它？

是的，你需要在main函数前加上声明，然后使用。
