Question

到现在为止，当我编译内核模块时，我安装了：kernel-devel，kernel-headers 后来，我不得不包含内核源代码所以我现在安装的软件包是为了编译我的内核模块：kernel-devel，kernel-headers和kernel.src.rpm（内核源代码）。
我正在创建一个“构建机器”，它将检查可用的最新内核，下载必要的软件包并为该内核编译内核模块。
我不想安装软件包，只是为了下载它，并将文件复制到它们的位置（下载kernel.src.rpm，rpm2cpio，cpio，并复制到/ lib / modules / kernel-X-Y /）我注意到如果安装了内核src，则不需要内核头文件。

需要kernel-devel ??，我不确定是什么，当尝试在没有kernel-devel的情况下安装时，我得到以下异常：

make[2]: Entering directory `/usr/src/kernels/3.10.0-693.el7.x86_64'

  ERROR: Kernel configuration is invalid.
         include/generated/autoconf.h or include/config/auto.conf are missing.
         Run 'make oldconfig && make prepare' on kernel src to fix it.
  WARNING: Symbol version dump ./Module.symvers
           is missing; modules will have no dependencies and modversions.

我错过了什么？如果我安装kernel-devel，那么我不会得到这个异常，我不想安装kernel-devel。

在运行make编译内核之前，您需要运行make oldconfig或将.config文件复制到构建树中。然后make oldconfig将使用.config并将其更新为更新的内核。

您还有其他选择：

内核源目录中的简单make help | grep -i config显示：

Configuration targets:
  config      - Update current config utilising a line-oriented program
  nconfig         - Update current config utilising a ncurses menu based
  menuconfig      - Update current config utilising a menu based program
  xconfig     - Update current config utilising a Qt based front-end
  gconfig     - Update current config utilising a GTK+ based front-end
  oldconfig   - Update current config utilising a provided .config as base
  localmodconfig  - Update current config disabling modules not loaded
  localyesconfig  - Update current config converting local mods to core
  silentoldconfig - Same as oldconfig, but quietly, additionally update deps
  defconfig   - New config with default from ARCH supplied defconfig
  savedefconfig   - Save current config as ./defconfig (minimal config)
  allnoconfig     - New config where all options are answered with no
  allyesconfig    - New config where all options are accepted with yes
  allmodconfig    - New config selecting modules when possible
  alldefconfig    - New config with all symbols set to default
  randconfig      - New config with random answer to all options
  listnewconfig   - List new options
  olddefconfig    - Same as silentoldconfig but sets new symbols to their
  kvmconfig   - Enable additional options for kvm guest kernel support
  xenconfig       - Enable additional options for xen dom0 and guest kernel support
  tinyconfig      - Configure the tiniest possible kernel
  kselftest-merge - Merge all the config dependencies of kselftest to existing
                    .config.
  configuration. This is e.g. useful to build with nit-picking config.
  i386_defconfig           - Build for i386
  x86_64_defconfig         - Build for x86_64
  make O=dir [targets] Locate all output files in "dir", including .config
