Linux编辑内核配置

下面简单介绍一下Linux内核编译过程

该操作时在Linux redhat 6.5进行操作，Ubuntu操作同理，只需要下载对应的Linux内核就可以

1.下载linux-2.6.37.tar.bz2

2.解压内核源文件

tar -xvf linux-2.6.37.tar.bz2 

这里我将文件解压到/usr/src目录下

3.导入配置

首先查看配置文件名称，这里我们可以看到有两个文件，我们选择x86_64_defconfig文件

[ configs]# pwd
/usr/src/linux-2.6.37/arch/x86/configs
[ configs]# ls 
i386_defconfig x86_64_defconfig

执行命令： make x86_64_defconfig 

注意：这里需要到解压目录下执行,执行成功之后，目录下回生成一个.config配置文件

[ linux-2.6.37]# make x86_64_defconfig
  HOSTLD  scripts/kconfig/conf
#
# configuration written to .config
#

4.执行make meunconfig命令，这里提示缺少ncurses-devel，使用yum进行安装

在Ubuntu下没有碰到这个问题

[ linux-2.6.37]# make menuconfig
 *** Unable to find the ncurses libraries or the
 *** required header files.
 *** ‘make menuconfig‘ requires the ncurses libraries.
 *** 
 *** Install ncurses (ncurses-devel) and try again.
 *** 
make[1]: *** [scripts/kconfig/dochecklxdialog] Error 1
make: *** [menuconfig] Error 2

5.使用yum安装ncurses-devel

[ mnt]# yum install -y ncurses-devel

6.再次执行make menuconfig命令，出现以下，这样就可以进行编辑内核了
