linux kernel内核的头文件获取、安装等方法，手动计算添加version.h

  • Post author:
  • Post category:linux


交叉编译时经常会用到这些头文件。


下载合适版本的linux


地址：

mirrors.aliyun.com/linux-kernel/

mirrors.edge.kernel.org/pub/linux/kernel/


解压：
 

biren@ubuntu:~/crossbuild/src$ tar jxf linux-3.9.tar.bz2


配置内核：
 

biren@ubuntu:~/crossbuild/src/linux-3.9$ make ARCH=arm menuconfig
  HOSTCC  scripts/kconfig/conf.o
  HOSTCC  scripts/kconfig/lxdialog/checklist.o
  HOSTCC  scripts/kconfig/lxdialog/inputbox.o
  HOSTCC  scripts/kconfig/lxdialog/menubox.o
  HOSTCC  scripts/kconfig/lxdialog/textbox.o
。。。

在这里插入图片描述


检查源文件中的头文件：


命令：make ARCH=arm headers_check

ARCH用于指定目标架构 

biren@ubuntu:~/crossbuild/src$ cd linux-3.9/
biren@ubuntu:~/crossbuild/src/linux-3.9$ make mrproper
biren@ubuntu:~/crossbuild/src/linux-3.9$ make ARCH=arm headers_check
  CHK     include/generated/uapi/linux/version.h
  UPD     include/generated/uapi/linux/version.h   此时会生成version.h文件
  HOSTCC  scripts/basic/fixdep
  WRAP    arch/arm/include/generated/asm/auxvec.h
  WRAP    arch/arm/include/generated/asm/bitsperlong.h
  WRAP    arch/arm/include/generated/asm/cputime.h
。。。
  WRAP    arch/arm/include/generated/asm/types.h
  WRAP    arch/arm/include/generated/asm/unaligned.h
  HOSTCC  scripts/unifdef
  INSTALL include/asm-generic (35 files)
。。。
  INSTALL include/uapi (0 file)
  INSTALL include/asm (34 files)
  CHECK   include/asm-generic (35 files)
  。。。
  CHECK   include/linux (382 files)
/home/biren/crossbuild/src/linux-3.9/usr/include/linux/kexec.h:49: userspace cannot reference function or variable defined in the kernel
/home/biren/crossbuild/src/linux-3.9/usr/include/linux/soundcard.h:1054: userspace cannot reference function or variable defined in the kernel
 。。。
  CHECK   include/uapi (0 files)
  CHECK   include/asm (34 files)


生成头文件：


make ARCH=arm INSTALL_HDR_PATH=./jwj/ headers_install

INSTALL_HDR_PATH=./jwj用于指定新的头文件存放目录 

biren@ubuntu:~/crossbuild/src/linux-3.9$ make ARCH=arm INSTALL_HDR_PATH=./jwj/ headers_install
  CHK     include/generated/uapi/linux/version.h  
  INSTALL jwj//include/asm-generic/ (35 files)
  INSTALL jwj//include/drm/ (15 files)
  INSTALL jwj//include/linux/byteorder/ (2 files)
  INSTALL jwj//include/linux/caif/ (2 files)
  INSTALL jwj//include/linux/can/ (5 files)

其中重要的几个是：asm, asm-generic, linux , uapi

uapi是从各模块抽取出来的用于启动内核相关的。

====================================


低版本的内核头文件获取

不需要以上步骤，只需从源码文件中复制出来即可。

如linux-2.6.10版本

存放在linux-2.6.10/include里 

biren@ubuntu:~/crossbuild/src/linux-2.6.10/include$ ls
acpi       asm-generic  asm-m68k       asm-ppc64  asm-sparc64  math-emu  rxrpc
asm-alpha  asm-h8300    asm-m68knommu  asm-s390   asm-um       media     scsi
asm-arm    asm-i386     asm-mips       asm-sh     asm-v850     mtd       sound
asm-arm26  asm-ia64     asm-parisc     asm-sh64   asm-x86_64   net       video
asm-cris   asm-m32r     asm-ppc        asm-sparc  linux        pcmcia

其中：asm-xxx对应asm, 选择适合的将它改名为asm即可，低版本中没有uapi目录

高版本中的asm存放在arch/arm/include下面。

====================================


如果要在系统中安装头文件可用如下命令：


apt-get install linux-headers 

sudo apt-get install linux-headers

  linux-headers-5.3.0-1044-gke 5.3.0-1044.47
。。。。。。


其它说明 ：

include/linux目录里必须有version.h，如果没有可以手动添加

方法如下：

（198912是版本0x03/0x09/0x00组合而成的0x030900的十进制) 

#define UTS_RELEASE "3.9.0"
#define LINUX_VERSION_CODE 198912
#define KERNEL_VERSION(a,b,c) (((a) << 16) + ((b) << 8) + (c))

获取本源码内核所支持的架构： 

biren@ubuntu:~/crossbuild/src/linux-2.6.10$ ls -d include/asm-* | sed 's/.*-//'
alpha
arm
arm26
cris
generic
h8300
i386
ia64
m32r
m68k
m68knommu
mips
parisc
ppc
ppc64
s390
sh
sh64
sparc
sparc64
um
v850
x86_64

或查看linux-2.6.10/arch目录
