ubuntu 内核源码下载及编译

1.查看当前系统原码版本

$ apt-cache search linux-source

linux-source - Linux kernel source with Ubuntu patches

linux-source-2.6.35 - Linux kernel source for version 2.6.35 with Ubuntu patches

2.下载源码

$ sudo apt-get install linux-source-2.6.35

下载完成后，在/usr/src目录中，可以看到压缩包

$ ls

linux-headers-2.6.35-22 linux-source-2.6.35

linux-headers-2.6.35-22-generic linux-source-2.6.35.tar.bz2

3.编译

$ sudo tar -xjvf linux-source-2.6.35.tar.bz2

$ sudo make menuconfig

HOSTCC scripts/basic/fixdep

HOSTCC scripts/basic/docproc

*** 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] 错误 1

make: *** [menuconfig] 错误 2

缺少ncurses库，安装

$ sudo apt-get install libncurses5-dev

重新编译成功。也可以使用系统原来的配置来编译，oldconfig

$ sudo make oldconfig #编译内核
