Debian kernel compilation experience

Debian kernel compilation experience-Linux Release Technology-Debian information. See the following for details. 1. Install the kernel compilation tool
Basic tools: gcc, libc5-dev or libc6-dev, binutils, make, bin86, modutils, mawk Or gawk, gzip, shellutils, grep, kernel-package, fakeroot
To use menuconfig for configuration, you need to install libncursesX. X-dev (for example: libncurses5-dev)
For kernels later than version 2.4, you can use xconfig on the graphic interface. You need to install tkX. X-dev (for example, tk8.4-dev)
For the 2.6 kernel, select more. If xconfig is used, you need to install the libqt3-mt-dev. If you do not want to use xconfig, you can use gconfig, you need to install libglade2-dev

# Apt-get install kernel-package ncurses-dev fakeroot initrd-tools select the basic tool based on your Linux release.

2. Install the kernel source code, such:
# Apt-get kernel-source-2.6.22.9 kernel directly downloads kernel-source-2.6.22.9.tar.gz and directly stores it in the/usr/src directory.

3. decompress the kernel source code
# Tar zxvf/usr/src/kernel-source-2.6.22.9.tar.gz
# Cd linux-2.6.22.9
# Cp/boot/config-2.6.22.9. config // The current Kernel configuration as a template/boot/config-2.6.22.9 depends on your own kernel version file.

4. Compile the kernel

1) Configuration
Make config uses the text dialog method (very troublesome, not easy to use)
Make menuconfig)
Make xconfig or make gconfig use GUI (very useful, but not stable)

Configuration is also the most troublesome step. N multiple choices. If you want to use. config as a template, load it at the beginning of configuration.

2) Clear the source code tree and restore the kernel-package parameter.
# Make-kpkg clean

3) Compile
# Make-kpkg -- revision = mykernel.1.0 -- initrd kernel_image

Mykernel.1.0 can be customized to indicate that it may take longer to compile the kernel by kernel name and number (generally more than one hour), depending on the performance of different machines.

5. Install the kernel
The compiled kernel is a deb package, which is placed in the/usr/src directory and can be directly installed using the dpkg command, such:

# Dpkg-I ../kernel-image-2.6.22.9-mykernel.1.0_i686.deb

If the installation is successful without any errors, the kernel has been compiled successfully, and the menu. lst's boot menu has been automatically modified.

VFS: Cannot open root device "hdb7" or unknown-block (0, 0)
Please append a correct "root =" boot option
Kernel panic-not syncing: VFS: unable to mount root fs on unknow-block (0, 0)

If this is prompted, some of the basic tools for Kernel compilation may not be installed. Let's take a look at them and compile them several times!
