用iccavr写的循迹小车程序出错了 不知道怎么改

Turn_left()和Turn_right()这些函数我都在drv.h中定义过了 怎么还会出错呢？我该怎么办呢？

把代码拷到别的盘看看。 有些软件路径不能有中文名和空格。

把ICC卸载了从新装一遍试试！不要用中文目录

!ERROR file 'xiaoche.o': undefined symbol '_Turn_left'
!ERROR file 'xiaoche.o': undefined symbol '_left_move'
!ERROR file 'xiaoche.o': undefined symbol '_Turn_right'

看看你的头文件包含全了吗?
