关于C51中.h文件的调用

只看该作者 · 2007-9-11 10:51

我是头一次接触C51编程
基本还是按照C的思路走
可是编写了几个文件也分别定义了头文件后，用主函数用＃include调用这些头文件，总是报警告：
*** WARNING L16: UNCALLED SEGMENT, IGNORED FOR OVERLAY PROCESS
    SEGMENT: ?PR?LCDMREADDATA?LCD

*** WARNING L16: UNCALLED SEGMENT, IGNORED FOR OVERLAY PROCESS
    SEGMENT: ?PR?LCD_INIT?LCD

*** WARNING L16: UNCALLED SEGMENT, IGNORED FOR OVERLAY PROCESS
    SEGMENT: ?PR?LCD_WELCOME?LCD

*** WARNING L16: UNCALLED SEGMENT, IGNORED FOR OVERLAY PROCESS
    SEGMENT: ?PR?LCD_TEST?LCD

*** WARNING L16: UNCALLED SEGMENT, IGNORED FOR OVERLAY PROCESS
    SEGMENT: ?C_INITSEG

*** WARNING L10: CANNOT DETERMINE ROOT SEGMENT

请各位高手指点一下，在C51中调用其他的void函数应该如何调用呢？？
谢谢拉：）
