刚学STM，用keil进行简单的编译，什么代码都提示有个错误，#include<stdio.h>
int main(void)
{
while(true)
{
;
}
}
*** Using Compiler 'V5.05 update 2 (build 169)', folder: 'D:\Keil_v5\ARM\ARMCC\Bin'
Build target 'Target 1'
linking...
.\Objects\EXAMPLE.axf: Error: L6218E: Undefined symbol main (referred from __rtentry2.o).
Not enough information to list image symbols.
Finished: 1 information, 0 warning and 1 error messages.
".\Objects\EXAMPLE.axf" - 1 Error(s), 0 Warning(s).
Target not created.
谁能帮忙看下是什么原因，拜托

报错的意思是Undefined symbol main 没有定义main，你的启动文件添加了吗，不是跟你说最好用keil4嘛
启动文件是什么，我已经下了5，就用5了
