Compile 2.6.X Kernel

Compile 2.6.X kernel-general Linux technology-Linux programming and kernel information. The following is a detailed description. We have compiled a new kernel 2.6.24 today. The following is a reference article for compilation.

1. Obtain the linux source file
Download linux-2.6.x.tar.gz to/usr/src from ftp://ftp.kernel.org/pub/linux/kernel/v2.6

2. su to root user

3. The next command sequence is to compile the kernel.
# Cd/usr/src
# Tar xzvf linux-2.6.x.tar.gz unzip to linux-2.6.x directory
# Mv linux-2.6.x linux-2.6.x-1 modify directory name
# Ln-s linux-2.6.x-1 linux creation Link
# Cd linux
# Vi Makefile modify kernel extension version
Modify EXTRAVERSION to-1 (or other characters, which corresponds to the directory name)
# Make mrproper clear garbage
# Make menuconfig select the kernel Option
This step is the most troublesome. There are a lot of things to choose from, using the IBM Library
Students can be in http://www.w-m-p.com/kconfig-2.6.2-rc2-mm1.txt
Find a configuration file. If it is found (maybe not found), copy it
/Usr/src/linux/and rename it to. config, and then run this command to fine tune

# Make bzImage compile the kernel
# Make modules compilation Module
# Make modules_install installation Module
(Note: it is best for debian IBM users to install module-init-tools)

# Depmod-
(It seems you can do it without using it)

4. Modify startup (for lilo and grub, you can see the configuration file)
# Cp/usr/src/linux/System. map/boot/System. map-2.6.x-1
# Cp/usr/src/linux/arch/i386/boot/bzImage/boot/vmlinuz-2.6.x-1
Use the specific version number to differentiate different kernels. In this way, you can select different kernels to start at the beginning.
# Vi/etc/lilo (Add the following content, which will be displayed in the lilo boot list in the future)

Image =/boot/vmlinuz-2.6.x-1
Label = Linux-2.6.x-1
Read-only
Optional

# Lilo-v
(Note: This step is very important !!)

5. # reboot
Then you can select a new kernel to start. If you do not like it, you can select the previous kernel.
