I am trying to build 32-bit linux kernel 2.6.9 on a 64-bit linux host with 2.6.9 (same version). Did some google search and tried the following:
我正在尝试在一个64位linux主机上构建32位的linux内核2.6.9，并使用2.6.9(相同的版本)。进行了谷歌搜索，并尝试了以下步骤:
step 1) make ARCH=i386 CFLAGS=-m32 menuconfig
步骤1)制作ARCH=i386 CFLAGS=-m32 menuconfig。
step 2) make ARCH=i386 CFLAGS=-m32
步骤2)制作ARCH=i386 CFLAGS=-m32。
Step 1 was okay. But step 2 got the following errors. What did I do wrong?
步骤1是好的。但是步骤2有以下错误。我做错了什么?
make ARCH=i386 CFLAGS=-m32

The make ARCH=i386 should be sufficient assuming you have everything required by the build installed on the machine. I use this almost daily to build i386 on a "ubuntu 12.04".
如果您拥有在机器上安装的构建所需的一切，那么make ARCH=i386应该足够了。我几乎每天都用它在“ubuntu 12.04”上构建i386。
If you have built a 64-bit kernel previously, you should have everything, and it's possible that you need to "make clean" or even "make mrproper" [save your .config somewhere safe for the latter], because I know for example asm_offsets.s will be different between 32 and 64-bit.
如果您之前已经构建了64位内核，那么您应该拥有一切，并且您可能需要“进行清理”，甚至“让mrproper”(为后者保存您的.config)，因为我知道例如asm_偏移。在32位和64位之间是不同的。
