Error in compiling a Linux kernel

Question

How do you read the errors?

I run after having .config -file at /home/aal/build/kernel.

/usr/src/linux-2.6$ make O=/home/aal/build/kernel/

I get

  ... cut ...

Answer 1

Remove the reference to that driver from your .config and the issue will go away. Alternately if you need the driver appropriate the source.

All of those errors are caused by the missing header.

Answer 2

错误存在于暂存驱动程序中，即尚未出现或尚未稳定的驱动程序中（例如， 在此处查看有关暂存树的讨论。）您可以在内核配置设备驱动程序->暂存驱动程序中禁用这些错误。

Answer 3

The errors probably all stem from the missing file in the first error.

I'd suspect include path or incomplete install of the sources...
