编译内核模块 - 需要什么包

Question

直到现在，当我编译内核模块时，我安装了:kernel-devel、kernel-headers。
后来，我不得不包括内核源代码。
所以现在我为了编译我的内核模块而安装的包是: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、下载必要的包并为该内核编译内核模块。
我不想安装这个包，只是想下载它，然后将文件复制到它们的位置(下载 kernel.src.rpm、rpm2cpio、cpio，然后复制到/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。

kernel-devel is needed ??，我不确定是否需要，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。 make oldconfig 将使用 .config 并将其更新到较新的内核。

您还有其他选择:

一个简单的make help | grep -i config 在内核源码目录下显示:

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
