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
