1. ccs工程的头文件找不到，怎么回事
1、要在Memory Section Manager属性中为“Segment For DSP/BIOS Objects” 和 “Segment For malloc()/free()”分配Dynamic Memory Heaps，必须首先在要分配的段（比如，IRAM）中勾选“create a heap in this memory“，并给出heaps size。
2、要把*.tcf文件生成的*.cmd文件手动加入工程中，否则编译报错如下：

warning 的原因是对应行的元素没有声明。
解决办法就是加入声明。
举例如下：
#include <std.h>
#include <string.h>
//#include <stdio.h> //打开该句就可以了
void main(void)
{
unsigned int i;
unsigned int sum=0;
for(i = 0; i<=100; i++ )
{
sum += i;
}
printf("the sum = %d .\n",sum);
printf("the program run over!\n");
printf("the program run over!\n");
2. CCS3.3编译提示cmd中提示找不到*.OBJ文件，可是debug里面明明有obj文件啊
error: system error, can't open file '/.obj' for input: No such file or directory
对应解复决办法：1要在cmd文件中制的vectors.obj前面添加-x.\Debug\代码才可以正常运行。
2要进行Project→Build options ---basic---Auto mod ----No auto即可
3. 为什么我的CCS3.3软件安装时出现找不到源文件，忽略这项安装后写程序编译提示出错
设置路径 project=>build options => compiler下的preprocesser，有个include search path，就可以设定头文件了，ok
4. 错误:CCS在链接时出现lib文件找不到
而是楼书的库有复问题，“制member 'csl.obj' has incompatible byte ordering”，估计是大端小端的问题，可能是该库在编译的时候所选用的便宜参数和你的project环境不同，建议楼主重新编译该该库，然后替换原来的。
5. ccs6编译工程和文件时总出现这个，怎么办啊，急
低版本是无法兼容高版本的文件的，只能升级cssv6，下载后，然后在项目右键 properties中选到general,选complier version 旁边的more就可以选你安装。
利用CCSv5导入之前版本工程（*.pjt）的方法
其实很简单，使用File-Import
只不过是不要选版择(General)Existing Projects into Workspace，那里会提示“Some projects cannot be imported because they already exist in the workspace”，而是要在Import的时候选择（Code Composer Studio）Legacy CCSv3.3 Projects
进入后直接选择相应的*.pjt文件
之后没有特殊要求就权一路Next直到Finish就好啦。导入后Build应该没问题。
至于Debug的需求，还是需要新建Target Configuration File，按需要选择仿真器，就可以了。
