电脑绕线机程序代码

struct save
{
unsigned char code;
unsigned int  d;
unsigned int  n;
unsigned int  w;
}str[50];
struct save str[50]__attribute__((section(".eeprom")));
extern struct style style_buffer;
//********************************************************************
void save(void)
{eeprom_write_block(style_buffer,str[style_buffer.code],6);}
//*******************
我这里定义的全局变量style_buffer怎么提示错误
../sxj009.c:497: error: 'style_buffer' has an incomplete type
请大哥大姐指点一下GCC编译有12个错误这个定义不了，兄弟我想diy电脑绕线机这读写eeprom时编译不过，
要是解决了请邮件asiaschain@yahoo.com.cn

下面是全部源代码

不顶自己顶，这个程序这eeprom问题不解决就没啥意义:L.

save被多次定义。

大师啊大师，正是这个问题，现在可以生成hex文件，可是那pc输出lcd是不是不行啊，
我用其他程序试了，pc段做12864的数据口不显示，用pb口就可以显示，是我设置有问题还是，atmega16的pc口不能用作lcd数据口呢

:):):);P呵呵呵

贴出完整的编译出错信息和相关的程序行

Lee老师新年好！使能了JTAG？

这个是个基础问题，因为我是非专业的 ，据说要关闭JTAG，可是我还不敢，是不是关闭后就不能用便宜的烧写，李老师，我c语言能自学，可是这单片的基础，网上找不到教材，能指点么，:)

:lol

楼主你的错误改正了没？
