linux2.6.21 make zImage时出现的错误

document.body.oncopy = function() {

var text = clipboardData.getData("text");
if (text && text.length>300) {
text = text + "/r/n/n本文来自CSDN博客，转载请标明出处：" + location.href;
clipboardData.setData("text", text);
}
}, 100);
}
}

function StorePage(){d=document;t=d.selection?(d.selection.type!='None'?d.selection.createRange().text:''):(d.getSelection?d.getSelection():'');void(keyit=window.open('http://www.365key.com/storeit.aspx?t='+escape(d.title)+'&u='+escape(d.location.href)+'&c='+escape(t),'keyit','scrollbars=no,width=475,height=575,left=75,top=20,status=no,resizable=yes'));keyit.focus();}
1.invalid option `abi=aapcs-linux'选项错误

解决的方法

You're building an EABI kernel with an OABI compiler. You can either
turn off the EABI option in your config file (Kernel Features->Use
EABI),or, you can use an EABI toolchain such as the ARM/GNU Linux one
from
<http://www.codesourcery.com/gnu_toolchains/arm/download.html>.I
recommend the latter, because then you can run Arjan's new images.

上述的关掉EABI选项可以通过测试

2.
`rtc_lock'未定义错误（未完全解决）

drivers/built-in.o(.text+0x281e4):drivers/char/nvram.c:350: more undefined references to `rtc_lock' follow

查找
drivers/char
/nvram.c有关的rtc_lock定义，发现2.6.21与以往的kernel不同，于是在包含文件中查找，在include/linux
/mc146818rtc.h中发现了rtc_lock的定义，但是有一个__KERNEL__的条件编译选项，去掉这个条件编译选项，再make
zImage，但是问题好像依然存在，继续在
drivers/char/nvram.c中增加这个定义spinlock_t rtc_lock;再编译，发现编译通过。

3.make zImage和make xipImage

Kernel configured for XIP (CONFIG_XIP_KERNEL=y)

Only the xipImage target is available in this case

make[1]: *** [arch/arm/boot/zImage] Error 1

make: *** [zImage] Error 2

好
象是make menuconfig的时候Boot options--->Kernel Execte-In-Place from
ROM选项问题，去掉这个选项编译通过（如果是make xopImage时則需要将这个选项选上），最终成功编译了make zImage。
