M0内核Air001移植RT-Thread出现问题？

通过教程安装RTOS之后编译便出现以下错误：
```
.\Output\Debug\Project.axf: Error: L6200E: Symbol main multiply defined (by components.o and system_air001xx.o).
Not enough information to list image symbols.
Not enough information to list load addresses in the image map.
Finished: 2 information, 0 warning and 1 error messages.
".\Output\Debug\Project.axf" - 1 Error(s), 0 Warning(s).
```

有两个main的入口点，components.c的无法编辑改变，而注释掉另一个文件的main则会引入以下错误
```

请问该如何解决此问题？
