0：错误：（500）未定义的符号：

嗨，朋友们，我用的是P18F420。我的AD转换程序工作得很好，但是因为我把程序的LCD部分分割成一个新的项目，然后把LCD.H文件包含到AD转换器文件中，它给出了这个：“0：错误：（500）未定义的符号：”。两个文件都在MPLABX项目文件夹中。这就是我在Ad转换器程序中所包含的内容：γ包含“…/LCDY4BITYMODEX.X/4BITYLCD.H”。我的意图是使代码非常模块化，一次写入多次。任何帮助都将是非常感谢。此外，LCD功能定义没有下划线前缀。我真的不知道为什么把它插在这里。我正在使用XC8 V4.05和MPLABX。完全错误消息：：（1233）使用18F420勘误工作：：：（1234）*损坏的快速中断阴影寄存器：：（1273）在自由模式下不可用的全知代码生成：0：错误：（500）未定义的符号：YLCDCH命令（DIST/D）Erg/AudioAddix.x.Sudio.Obj.O.LCD.WrdWr.EdCurr.x.Studio .Obj.LCDCDIIT（DIST/Deule/SudioAdTurn.x.Pult.Obj.）（908）退出状态＝1nbPosi/MaFaMeCurrime.MK：131：目标“DIST/Deule/Dealth/AdCurtoTr.x.PRODU”的配方cx.Hex'FultEdv[[ 2 ] ]：离开目录'C://Puls/MPLABXPix/Addix.x'NbPosi/MaFaMeCurrase.MK: 90：目标''.Buffic CONF 'FultEdvest[[ 1 ] ]：离开目录'C:/Ups/Upvs/MPLABXPosi/AdTurn.x'NbPosi/MaqFixIMP.MK:39：目标''.dGue[ 2 ]：**[Dist/Deult/Addix.x.Engult.HEX]错误1]使[1 ]：**[Bug CONF]错误2:使：**[构建IMPL]错误2Bug失败（退出值2，总时间：4s）

    Hi Friends,
I am using P18F4520. My AD conversion program worked fine but since i separated the LCD part of the program into a new project and then included LCD.h file into the AD converter file; it gives this ":0: error: (500) undefined symbols:"  . Both files are in the MPLABXProjects folder.  This is how i included in the ADConverter program: #include "../LCD_4bit_Mode.X/4bit_LCD.h". My intention is to make the codes very modular and write once and multiple times. Any help will be so much appreciated.

In addition, the LCD functions are defined without underscore prefix. i really don't know why it is inserting it here. I am using XC8 v4.05 and MPLABX.
