Question

我正在尝试在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内容：

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

步骤2）使ARCH = i386 CFLAGS = -m32

第1步没问题。但是第2步出现了以下错误。我做错了什么？

make ARCH=i386 CFLAGS=-m32

假设您拥有计算机上安装的构建所需的所有内容，make ARCH=i386就足够了。我几乎每天使用它来在“ubuntu 12.04”上构建i386。

如果您之前已经构建了64位内核，那么您应该拥有所有内容，而且您可能需要“干净”甚至“make mrproper”[将.config保存到后者安全的地方]，因为我例如，asm_offsets.s将在32位和64位之间有所不同。
