linux内核配置与编译

时间:2021-03-23 16:35:27

清除临时文件、中间文件和配置文件命令:

make clean //remove most generated files but keep the config
make mrproper //remove all generated files + config files
make distclean //mrproper + remove editor backup and patch files

配置内核命令:

make config:基于文本模式的交互式配置。

make menuconfig ARCH=i386:基于文本模式的菜单型配置。//“*”编译成内核(按y)(生成镜像),“m”编译成模块(按m)(生成点o文件),“ ”为不编译(按n)

配置完成之后会在当前文件夹下生成.config文件。

Linux内核提供了一系列可供参考的内核配置文件,位于./arch/$cpu/configs

编译内核:

make zImage//获取详细信息make zImage V=1

make bzImage//获取详细信息make bzImage V=1

区别:在X86平台,zImage只能用于小于512K的内核

编译好的内核文件位于./arch/$cpu/boot/(文件名为bzImage)。

编译内核模块:

make modules 

安装内核模块:

make modules_install

将编译好的内核模块从内核源代码目录copy至/lib/modules下,文件夹名为该内核版本号如2.6.29。

制作init ramdisk:

即将/lib/modules下的内核文件夹生成init ramdisk文件。

mkinitrd initrd-$version $version //例mkinitrd initrd-2.6.29  2.6.29

内核安装:

将bzImage文件和init ramdisk文件都复制到/boot/ 下。

如上文中的initrd-2.6.29,以及编译好的内核文件bzImage如重命名为vmlinuz-2.6.29。

并且修改/etc/grub.conf 或者 /etc/lilo.conf。

如:

default=1
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Red Hat Enterprise Linux Server (2.6.18-53.el5)
root (hd0,0)
kernel /vmlinuz-2.6.18-53.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.18-53.el5.img
title newlinux
root (hd0,0)
kernel /vmlinuz-2.6.29 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.29
