老是提示编译错误*** ERROR L118: REFERENCE MADE TO ERRONEOUS EXTERNAL SYMBOL: MAIN MODULE: D:\51开发\C51\LIB\C51S.LIB (?C_INIT) ADDRESS: 080DHProgram Size: data=17.0 xdata=0 code=321Target not created
谁帮我看看，这个程序问题出在哪里
#include#define uchar unsigned char#define uint unsigned intsbit LED=P1^0;//延时void DelayMS(uint x){ uchar i; while(x--) { for(i=0;i<120;i++); }}//主程序void main(){ while(1) { LED=~LED; DelayMS(150); }}
