ccs3.3中编译时出错，请指教

"main.c", line 17: [E094] declared symbol 'SystemInit' is not a parameter
"main.c", line 18: [E094] declared symbol 'KickDog' is not a parameter
"main.c", line 22: [E094] declared symbol 'main' is not a parameter
"main.c", line 22: [F001] syntax error at or near symbol '{'

上面错误是什么意思啊，怎么解决呢？

解决了吗，说说方法，我们学习一下啊
