warning: #1-D: last line of file ends without a newline 什么

#include <stm32f10x_lib.h> int a; main() { ; } 我程序就剩上面的了，怎么还警告啊 compiling STM32_Init.c... compiling kun_fun_C.C... kun_fun_C.C(9): warning:  #1-D: last line of file ends without a newline linking... Program Size: Code=308 RO-data=252 RW-data=0 ZI-data=608   "kun_fun.axf" - 0 Error(s), 1 Warning(s).

解决方法：
