运行cmd,输入c:回车,输入cd TC20H回车,输入cd BGI回车,输入BGIOBJ EGAVGA回车(此时BGI文件里面已经有EGAVGA.OBJ文件了);在c:/TC20H文件夹下运行命令:TLIB LIB/GRAPHICS.LIB+EGAVGA:回车,输入cd TC20H回车,输入TLIB LIB\GRAPHICS.LIB+EGAVGA回车,并且在源程序中initgraph()函数调用之前加上一句:
registerbgidriver(EGAVGA_driver):
initgraph( gdriver, gmode,"c:\\TC20H\\BGI");,代码使用的是,清华大学出版社的,【c语言经典编程282例】的源代码的,但是编译时出现了英文,undefined symbol egavga driver in module.
registerbgidriver(EGAVGA_driver):
initgraph( gdriver, gmode,"c:\\TC20H\\BGI");,代码使用的是,清华大学出版社的,【c语言经典编程282例】的源代码的,但是编译时出现了英文,undefined symbol egavga driver in module.

是不是在dos下运行c:\cd\tc的,\运行cmd,输入c:回车,输入cd TC20H回车,输入cd BGI回车,输入BGIOBJ EGAVGA回车(此时BGI文件里面已经有EGAVGA.OBJ文件了);在c:/TC20H文件夹下运行命令:TLIB LIB/GRAPHICS.LIB+EGAVGA:回车,把Turbo c2.0的bgi驱动在dos模式下加进去的? 你说怎们办的?你的编程技术肯定比我强的,因为你回答了我的问题的,但是你的步奏回答详细点不可以吗?我是刚入c语言编程世界的小虫的,花费了,一整年的功夫拿下了,谭浩强的,c语言程序设计(2版)的,

回复:
以下假设你的TC装在C:\TC下:
Turbo C对于用initgraph()函数直接进行的图形初始化程序, 在编译和链接
时并没有将相应的驱动程序(*.BGI)装入到执行程序, 当程序进行到intitgraph()
语句时, 再从该函数中第三个形式参数char *path中所规定的路径中去找相应的
驱动程序。若没有驱动程序, 则在C:\TC中去找, 如C:\TC中仍没有或TC不存在,
将会出现错误:
BGI Error: Graphics not initialized (use 'initgraph')
因此, 为了使用方便, 应该建立一个不需要驱动程序就能独立运行的可执行
图形程序,Turbo C中规定用下述步骤(这里以EGA、VGA显示器为例):
1. 在C:\TC子目录下输入命令:BGIOBJ EGAVGA
此命令将驱动程序EGAVGA.BGI转换成EGAVGA.OBJ的目标文件。
2. 在C:\TC子目录下输入命令:TLIB LIB\GRAPHICS.LIB+EGAVGA
此命令的意思是将EGAVGA.OBJ的目标模块装到GRAPHICS.LIB库文件中。
3. 在程序中initgraph()函数调用之前加上一句:
registerbgidriver(EGAVGA_driver):
该函数告诉连接程序在连接时把EGAVGA的驱动程序装入到用户的执行程序中。
经过上面处理,编译链接后的执行程序可在任何目录或其它兼容机上运行。
它要用到bgi驱动程序.如egavga.bgi.把他拷贝到你的可执行文件所在目录
你也可以把他连接到你的exe文件中去.
用int registerbgifont(void(*driver)(void));
int registerbgifont(void(*font)(void));
之前,你要到tc目录下的lib目录下输入
BGIOBJ EGAVGA 回车(把tc目录的bgiobj.exe考到/lib目录)
有一个egavga.obj文件生成
再用tc目录下的什么lib.exe
lib graphics.lib+egavga.ogj 回车
之后,在你的代码中initgraph()前加上registerbgidriver(EGAVGA_driver);

读者你好,你可以用别的编译器试试,比如vc++6.0或是vs,dev,都可以实现贪吃蛇的运行,你可以试试。
