无法在 Ubuntu 20.04 上安装 Linux 内核

Question

我是内核社区的新手，我正在学习如何编译和安装 Linux 内核，但我无法安装它。我正在运行ning 6 核 Ryzen 5 和 Ubuntu 20.04 LTS，我的编译器使用 gcc。我当前的内核版本是 5.11.0-38-generic，我正在尝试编译和安装 5.14.14 版本。我使用 Greg Kroah Heartman 的 Linux 内核简而言之作为指南。首先，我从 kernel.org 下载最新的主线内核。然后，我运行 make menuconfig 为我的系统生成一个 .config。接下来，我运行 make -j12 编译内核，运行没问题 return 没有任何错误。我在安装它时遇到了运行麻烦。在运行ning make install 之后，我得到以下错误输出：

arch/x86/Makefile:148: CONFIG_X86_X32 enabled but no binutils support
sh ./arch/x86/boot/install.sh \
    5.14.14 arch/x86/boot/bzImage \
    System.map "/boot"

 *** Missing file: arch/x86/boot/bzImage
 *** You need to run "make" before "make install".

make[1]: *** [arch/x86/boot/Makefile:161: install] Error 1
make: *** [arch/x86/Makefile:280: install] Error 2

install.sh 告诉我在我的 arch 目录中没有 bzImage 文件。我检查了一下，确实文件丢失了。我尝试查找“丢失的 bzImage 文件”，但找不到任何有用的信息。为什么不生成一个大的 zImage 文件？

我在上面的评论中尝试了 Justin Iurman 的建议，它适用于安装内核。我需要在 make 之前运行 make bzImage。在 make bzImage 成功之前，我必须在配置文件中编辑一行。但是，sudo make install 给出了一些奇怪的输出：

arch/x86/Makefile:148: CONFIG_X86_X32 enabled but no binutils support
sh ./arch/x86/boot/install.sh \
    5.14.14 arch/x86/boot/bzImage \
    System.map "/boot"

看来我虽然可以安装内核，但没有正常启动，但由于我的问题是安装内核，所以我将此问题标记为已关闭。
