我是个新手，使用CCS5.5编译出现了点问题，不知道要怎么搞

请您详细说明下您的信息。您现在使用的板子以及程序是什么？

//
// ASSUMPTIONS:
//
// This program requires the DSP2833x header files.
//
// Other then boot mode configuration, no other hardware configuration
// is required.
//
//
// 根据在RAM中调试的需要，这个项目配置成"boot to SARAM".2833x引导模式
// 表如下显示. 常用的还有"boot to Flash"模式，当程序在RAM调试完善后就
// 可以将代码烧进Flash中并使用"boot to Flash"引导模式.

// DESCRIPTION:
//
// This example configures CPU Timer0, 1, and 2 and increments
// a counter each time the timers assert an interrupt.
//
// Watch Variables:
// CpuTimer0.InterruptCount
// CpuTimer1.InterruptCount
// CpuTimer2.InterruptCount

我试了一下并没有出现错误（新建工程测试）

请您右键点击错误 选择 properties 看一下具体是什么错误

就是这个样子的，麻烦看一下
