#include <io8515.h>
#define uchar unsigned char

void main(void)
{
DDRA = 0x0;
}

答 1: 怎么不会过！我把您的程序复制到ICC中，编译通过。也能够生成所需的代码。
是否是扩展名错，应为“.C”。 答 2: 是不是头文件不对？// CodeVisionAVR C Compiler

答 3: 是ICCAVR 6.26版本编译应是路径设置不对！检查路径。
在6.26中，应改为io8515v.h
答 4: 编译应该能通过，但可能有警告。 答 5: ICC安装时目录不能有空格。如：program files是不行的。 答 6: 试试看将项目放在\**\**\bin目录下、头文件名称后加v试试看 答 7: :)(没有问题呀！
