我试图编译和链接使用XC8编译的C程序。 我从C18编译器改变，做了一些小的兼容性修改代码。 随着C18，代码编译和链接就好了。 随着XC8，编译去罚款，但链接步骤失败，此错误：
Error [500] ; 0. undefined symbols:
_putch(server.obj) _ENC_Init(server.obj) _ENC_WriteRegister(server.obj) _ENC_ReadRegister(server.obj)
由于编译成功，我想找到原型，ERGO的.h文件包括没关系。 我猜编译器无法找到.c文件。
该功能putch是不是在我自己的程序中调用，但它叫putchar和我使用的功能。 首先是功能ENC_是我自己的功能。
我添加了两个路径到XC8工具包的“包含搜索路径”：
-
C:\Program Files (x86)\Microchip\xc8\v1.12\sources，编译器的程序.c文件的位置，我相信 -
C:\...\lib，那里有我自己.c文件的位置。
不过，我仍然得到错误。
我怎样才能解决这个问题呢？
这是一个完整的日志：
