题目是要求用纯C程编一个于电脑时间同步走的，显示3根走动的针，外面要有一个表盘的钟。（最好下面还带数字显示几点的）。还要求每走一格秒针表盘不会闪烁。这种题比较麻烦，还请各位高手帮帮忙，做一个看看。谢谢了先！

高手，大虾，谢谢帮忙！！

Linker Error: Undefined symbol '_EGAVGA_driver' in module O'CLOCK.H是那里错了，小弟不怎么懂啊。？[em48]

你用的什么编译器？ 用wintc可以编译成功的..........你用win-tc 1.8试试看 别的编译器我没有试过

o  ,我用的是TC2。0啊，我再试试吧，。

连接时出了问题，一个常量没有定义，你只要再定义下就OK了
for example:
#define EGAVGA_driver=10;
^_^这个问题我也搞了很久才明白那时个常量
