Kernel compilation in Ubuntu9.10

Now the latest kernel version is 2.6.32, and the kernel version that comes with MySQL 9.10 is 2.6.31-20. The difference between the two is not great. Therefore, the main purpose of this article is to familiarize yourself with the kernel compilation process and lay a good foundation for the following kernel programming. The experimental environment is Ubuntu9.10 in VirtualBox. 1, download the linux-2.6.32, a lot of ways, do not specify 2, unzip to/usr/src/root @ globus-laptop :~ # Ls/usr/src/l

Now the latest kernel version is 2.6.32, and the kernel version that comes with MySQL 9.10 is 2.6.31-20. The difference between the two is not great. Therefore, the main purpose of this tutorial is to familiarize yourself with the kernel compilation process and lay a good foundation for Kernel programming. The experimental environment is Ubuntu 9.10 In VirtualBox.

1, download the linux-2.6.32, a lot of ways, not specific description

2. decompress the package to/usr/src /.
Root @ globus-laptop :~ # Ls/usr/src/ls/usr/src
Linux-headers-2.6.31-14-generic vboxguest-3.1.0
Linux-2.6.32 linux-headers-2.6.31-20 vboxvfs-3.1.0
Linux-headers-2.6.31-14 linux-headers-2.6.31-20-generic vboxvideo-3.1.0

3. Create a new link
Root @ globus-laptop :~ # Ln-s/usr/src/linux-2.6.14/usr/src/linux
Root @ globus-laptop :~ # Ls/usr/src/
Linux linux-headers-2.6.31-14-generic vboxguest-3.1.0
Linux-2.6.32 linux-headers-2.6.31-20 vboxvfs-3.1.0
Linux-headers-2.6.31-14 linux-headers-2.6.31-20-generic vboxvideo-3.1.0

4. Configure the kernel.
This process is troublesome. We use the configuration of previous versions.
Root @ globus-laptop :~ # Cd/usr/src/linux
Root @ globus-laptop:/usr/src/linux # uname-r
2.6.31-20-generic
Root @ globus-laptop:/usr/src/linux # cp/boot/config-2.6.31-20-generic. config
Start Configuration:
Root @ globus-laptop:/usr/src/linux # make xconfig
In this step, you may encounter the following problems:
HOSTCC scripts/kconfig/kconfig_load.o
Make [1]: *** No rule to make target 'scripts/kconfig/. tmp_qtcheck', needed by 'scripts/kconfig/qconf. o'. Stop.
Make: *** [xconfig] Error 2
Solution:
Apt-get install build-essential
Apt-get install libqt3-mt-dev
This is because xconfig requires libqt3-mt-dev
Make xconfig again
On the configuration page, select the desired configuration (most of the configuration has been completed by the. config file), save, and exit.

5. Start compilation.
Root @ globus-laptop:/usr/src/linux # make-kpkg clean
If no kpkg is displayed, follow the prompts to install it.
Root @ globus-laptop:/usr/src/linux # make-kpkg -- initrd-revision = first kernel_image kernel_headers
Long wait...

6. Install the new kernel.
After the kernel is successfully built, two. deb packages can be found in the/usr/src directory. One is the kernel installation package and the other is the kernel headers installation package.
Root @ globus-laptop:/usr/src # dpkg-I/usr/src/linux-image-2.6.32_first_i386.deb
Root @ globus-laptop:/usr/src # dpkg-I/usr/src/linux-headers-2.6.32_first_i386.deb

7. Restart.
