这是我在make 时候出的错。。。

我在make modules的时候出现以下错误

不太明白，我是我的make menuconfig哪里需要设置吗？

我现在也遇到这个问题，因为没有资料，所以只能自己摸索，经过查看，这些模块在板子上一般是用不到的，所以你只需要把这些模块关掉就行，你可以 make menuconfig 在图形界面关掉，也可以直接编译文件.config，我刚刚弄完了一部分，还剩这两个错误

再找找看。。。我下的是2.6.22.6的内核版本。

现在问题是解决了，剩下的两个模块在.config中没有找到，我去相应的makefile里关掉就没事了

我怎么找不到.config文件啊？

两个可能
1.你没产生出来,先用make menuconfig或找个适合的config吧
2.你不知道.config是隐藏档 ,用ls –a

我出现了这些错误，怎么该.config文件啊，我不知道怎么跟它的配置选项对应起来
