我的也是内核编译问题，不能进入内核配置界面……详细如下：

[cmwwy]

一
首先将linux-2.6.14.3.tar.gz解压到/usr/src目录下，并建立符号链接linux-2.6指向linux-2.6.14.3

二
在/usr/include目录下，有三个目录（不是符号链接）asm、linux、scis，我将它们改名，然后建立符号链接asm、linux、scsi
asm -> /usr/src/linux-2.6/include/asm-i386/
linux -> /usr/src/linux-2.6/include/linux/
scsi -> /usr/src/linux-2.6/include/scsi/

三
进入/usr/src/linux-2.6目录，然后打入命令：make menuconfig，输出结果如下：
[root@linux linux-2.6]# make menuconfig
HOSTCC scripts/basic/fixdep
HOSTCC scripts/basic/split-include
In file included from /usr/include/linux/errno.h:4,
from /usr/include/bits/errno.h:25,
from /usr/include/errno.h:36,
from scripts/basic/split-include.c:26:
/usr/include/asm/errno.h:4:31: asm-generic/errno.h: No such file or directory
make[1]: *** [scripts/basic/split-include] Error 1
make: *** [scripts_basic] Error 2
不能进入内核配置界面

四
重新进入/usr/include目录下，删除asm、linux、scsi符号链接，并将原先改名的asm、linux、scsi目录重新改名为asm、linux、scsi

五
重新进入/usr/src目录，删除linux-2.6符号链接，直接进入目录linux-2.6.14.3，打入命令：
root@linux linux-2.6.14.3]# make menuconfig
HOSTCC scripts/basic/fixdep
HOSTCC scripts/basic/split-include
HOSTCC scripts/basic/docproc
SHIPPED scripts/kconfig/zconf.tab.h

……下面都是类似于上面的输出……

最后能够进入配置界面：

  为什么我第一次不成功，第二次可以？？？而且在第二次的输出中有这样一句：
  # using defaults found in /boot/config-2.4.21-4.EL
  这是什么意思啊……

注意你在升级内核从2.4-2.6，你会遇到很多麻烦，因为并不是编译安装成功了就万事大吉。
你需要看一个文章。

关于你问的头文件的问题，linux-kernel 和 linux-kernel-header 现在已经是分开的两个工程。已经不是简单的在/usr/include下面作到 /usr/src/kernel-version/include 的连接。二是分开的，原因很简单因为 kernel的头文件需要 /usr/include 的 glibc的头文件的支持。所以你需要下在单独的头文件放在/usr/include里面
2.6.14得编译步骤是

make menuconfig
make
make install
然后拷贝 kernel .config Sysmap 到 /boot ，然后修改 /boot/grub/menu.lst就可以了。

在/usr/include目录下，有三个目录（不是符号链接）asm、linux、scis，我将它们改名，然后建立符号链接asm、linux、scsi
asm -> /usr/src/linux-2.6/include/asm-i386/
linux -> /usr/src/linux-2.6/include/linux/
scsi -> /usr/src/linux-2.6/include/scsi/


再加一个
asm-generic -> /usr/src/linux-2.6/include/asm-generic/

楼上的，根据linux kernel Team 的建议，直接引用/src/include的内容实际上是会出错的（虽然我编译也通过了，但是总是觉得怪怪的）

所以还是直接拷贝一份到/usr/include 里面较为稳妥
