Chapter 11.
Kernel build command line reference
As discussed in Chapter 5,
Configuring and Building
, the tool that
ties together kernel builds is the
make
program, to
which you pass a target that specifies what you want to build. Chapter 5,
Configuring and Building
went over the basic targets needed
to build the kernel properly, but the kernel build system also has a
wide range of other targets. This chapter details these targets, and
what they can be used for.
All of these targets are passed to the
make
program on
the command line, and a number of them can be grouped together if
desired. For example:
$
make mrproper xconfig
The targets are broken down into different types in the following
sections.
You can get a summary of most of these targets by running, within the build directory:
$
make help
This target prints out a lot of the common
make
targets that are described in the rest of this chapter.
These targets print the kernel version, based on a number of different
options. They are commonly used by scripts to determine the
version of the kernel being built.

Target
|
Description
|
kernelrelease
|
Displays the current kernel version, as determined by the build
system.
|
kernelversion
|
Displays the current kernel version, as told by the main Makefile. This differs from the
kernelrelease target in that it doesn't use
any additional version
information based on configuration options or localversion files.
