我正在尝试在具有 2.6.9（相同版本）的 64 位 linux 主机上构建 32 位 linux 内核 2.6.9。做了一些谷歌搜索并尝试了以下方法：

步骤 1) 使 ARCH=i386 CFLAGS=-m32 menuconfig

步骤 2) 使 ARCH=i386 CFLAGS=-m32

第 1 步没问题。但第 2 步出现以下错误。我做错了什么？

make ARCH=i386 CFLAGS=-m32

假设您已经在机器上安装了构建所需的一切，这make ARCH=i386应该足够了。我几乎每天都使用它在“ubuntu 12.04”上构建 i386。

如果您之前构建了一个 64 位内核，那么您应该拥有一切，并且您可能需要“make clean”甚至“make mrproper”[将您的 .config 保存在对后者安全的地方]，因为我知道例如asm_offsets.s 在 32 位和 64 位之间会有所不同。
