Environment variables
|
||||
|
||||
KCPPFLAGS
|
||||
--------------------------------------------------
|
||||
Additional options to pass when preprocessing. The preprocessing options
|
||||
will be used in all cases where kbuild do preprocessing including
|
||||
building C files and assembler files.
|
||||
|
||||
KAFLAGS
|
||||
--------------------------------------------------
|
||||
Additional options to the assembler.
|
||||
|
||||
KCFLAGS
|
||||
--------------------------------------------------
|
||||
Additional options to the C compiler.
|
||||
|
||||
KBUILD_VERBOSE
|
||||
--------------------------------------------------
|
||||
Set the kbuild verbosity. Can be assinged same values as "V=...".
|
||||
See make help for the full list.
|
||||
Setting "V=..." takes precedence over KBUILD_VERBOSE.
|
||||
|
||||
KBUILD_EXTMOD
|
||||
--------------------------------------------------
|
||||
Set the directory to look for the kernel source when building external
|
||||
modules.
|
||||
The directory can be specified in several ways:
|
||||
1) Use "M=..." on the command line
|
||||
2) Environmnet variable KBUILD_EXTMOD
|
||||
3) Environmnet variable SUBDIRS
|
||||
The possibilities are listed in the order they take precedence.
|
||||
Using "M=..." will always override the others.
|
||||
|
||||
KBUILD_OUTPUT
|
||||
--------------------------------------------------
|
||||
Specify the output directory when building the kernel.
|
||||
The output directory can also be specificed using "O=...".
|
||||
Setting "O=..." takes precedence over KBUILD_OUTPUT
|
||||
|
||||
ARCH
|
||||
--------------------------------------------------
|
||||
Set ARCH to the architecture to be built.
|
||||
In most cases the name of the architecture is the same as the
|
||||
directory name found in the arch/ directory.
|
||||
But some architectures suach as x86 and sparc has aliases.
|
||||
x86: i386 for 32 bit, x86_64 for 64 bit
|
||||
sparc: sparc for 32 bit, sparc64 for 64 bit
|
||||
|
||||
CROSS_COMPILE
|
||||
--------------------------------------------------
|
||||
Specify an optional fixed part of the binutils filename.
|
||||
CROSS_COMPILE can be a part of the filename or the full path.
|
||||
|
||||
CROSS_COMPILE is also used for ccache is some setups.
|
||||
|
||||
CF
|
||||
--------------------------------------------------
|
||||
Additional options for sparse.
|
||||
CF is often used on the command-line like this:
|
||||
|
||||
make CF=-Wbitwise C=2
|
||||
|
||||
INSTALL_PATH
|
||||
--------------------------------------------------
|
||||
INSTALL_PATH specifies where to place the updated kernel and system map
|
||||
images. Default is /boot, but you can set it to other values
|
||||
|
||||
|
||||
MODLIB
|
||||
--------------------------------------------------
|
||||
Specify where to install modules.
|
||||
The default value is:
|
||||
|
||||
$(INSTALL_MOD_PATH)/lib/modules/$(KERNELRELEASE)
|
||||
|
||||
The value can be overridden in which case the default value is ignored.
|
||||
|
||||
INSTALL_MOD_PATH
|
||||
--------------------------------------------------
|
||||
INSTALL_MOD_PATH specifies a prefix to MODLIB for module directory
|
||||
relocations required by build roots. This is not defined in the
|
||||
makefile but the argument can be passed to make if needed.
|
||||
|
||||
INSTALL_MOD_STRIP
|
||||
--------------------------------------------------
|
||||
INSTALL_MOD_STRIP, if defined, will cause modules to be
|
||||
stripped after they are installed. If INSTALL_MOD_STRIP is '1', then
|
||||
the default option --strip-debug will be used. Otherwise,
|
||||
INSTALL_MOD_STRIP will used as the options to the strip command.
|
||||
|
||||
INSTALL_FW_PATH
|
||||
--------------------------------------------------
|
||||
INSTALL_FW_PATH specify where to install the firmware blobs.
|
||||
The default value is:
|
||||
|
||||
$(INSTALL_MOD_PATH)/lib/firmware
|
||||
|
||||
The value can be overridden in which case the default value is ignored.
|
||||
|
||||
INSTALL_HDR_PATH
|
||||
--------------------------------------------------
|
||||
INSTALL_HDR_PATH specify where to install user space headers when
|
||||
executing "make headers_*".
|
||||
The default value is:
|
||||
|
||||
$(objtree)/usr
|
||||
|
||||
$(objtree) is the directory where output files are saved.
|
||||
The output directory is often set using "O=..." on the commandline.
|
||||
|
||||
The value can be overridden in which case the default value is ignored.
|
||||
|
||||
KBUILD_MODPOST_WARN
|
||||
--------------------------------------------------
|
||||
KBUILD_MODPOST_WARN can be set to avoid error out in case of undefined
|
||||
symbols in the final module linking stage.
|
||||
|
||||
KBUILD_MODPOST_FINAL
|
||||
--------------------------------------------------
|
||||
KBUILD_MODPOST_NOFINAL can be set to skip the final link of modules.
|
||||
This is solely usefull to speed up test compiles.
|
||||
|
||||
KBUILD_EXTRA_SYMBOLS
|
||||
--------------------------------------------------
|
||||
For modules use symbols from another modules.

This file contains some assistance for using "make *config".
|
||||
|
||||
Use "make help" to list all of the possible configuration targets.
|
||||
|
||||
The xconfig ('qconf') and menuconfig ('mconf') programs also
|
||||
have embedded help text. Be sure to check it for navigation,
|
||||
search, and other general help text.
|
||||

======================================================================
|
||||
General
|
||||
--------------------------------------------------
|
||||
|
||||
New kernel releases often introduce new config symbols. Often more
|
||||
important, new kernel releases may rename config symbols. When
|
||||
this happens, using a previously working .config file and running
|
||||
"make oldconfig" won't necessarily produce a working new kernel
|
||||
for you, so you may find that you need to see what NEW kernel
|
||||
symbols have been introduced.
|
||||
|
||||
To see a list of new config symbols when using "make oldconfig", use
|
||||
|
||||
cp user/some/old.config .config
|
||||
yes "" | make oldconfig >conf.new
|
||||
|
||||
and the config program will list as (NEW) any new symbols that have
|
||||
unknown values. Of course, the .config file is also updated with
|
||||
new (default) values, so you can use:
|
||||
|
||||
grep "(NEW)" conf.new
|
||||
|
||||
to see the new config symbols or you can 'diff' the previous and
|
||||
new .config files to see the differences:
|
||||
|
||||
diff .config.old .config | less
|
||||
|
||||
(Yes, we need something better here.)
|
||||
|
||||

|
||||
menuconfig
|
||||
--------------------------------------------------
|
||||
|
||||
SEARCHING for CONFIG symbols
|
||||
|
||||
Searching in menuconfig:
|
||||
|
||||
The Search function searches for kernel configuration symbol
|
||||
names, so you have to know something close to what you are
|
||||
looking for.
|
||||
|
||||
Example:
|
||||
/hotplug
|
||||
This lists all config symbols that contain "hotplug",
|
||||
e.g., HOTPLUG, HOTPLUG_CPU, MEMORY_HOTPLUG.
|
||||
|
||||
For search help, enter / followed TAB-TAB-TAB (to highlight
|
||||
<Help>) and Enter. This will tell you that you can also use
|
||||
regular expressions (regexes) in the search string, so if you
|
||||
are not interested in MEMORY_HOTPLUG, you could try
|
||||
|
||||
/^hotplug
|
||||
|
||||
|
||||

||||
Color Themes for 'menuconfig'
|
||||
|
||||
It is possible to select different color themes using the variable
|
||||
MENUCONFIG_COLOR. To select a theme use:
|
||||
|
||||
make MENUCONFIG_COLOR=<theme> menuconfig
|
||||
|
||||
Available themes are:
|
||||
mono => selects colors suitable for monochrome displays
|
||||
blackbg => selects a color scheme with black background
|
||||
classic => theme with blue background. The classic look
|
||||
bluetitle => a LCD friendly version of classic. (default)
|
||||
|
||||

|
||||
Environment variables in 'menuconfig'
|
||||
|
||||
KCONFIG_ALLCONFIG
|
||||
--------------------------------------------------
|
||||
(partially based on lkml email from/by Rob Landley, re: miniconfig)
|
||||
--------------------------------------------------
|
||||
The allyesconfig/allmodconfig/allnoconfig/randconfig variants can
|
||||
also use the environment variable KCONFIG_ALLCONFIG as a flag or a
|
||||
filename that contains config symbols that the user requires to be
|
||||
set to a specific value. If KCONFIG_ALLCONFIG is used without a
|
||||
filename, "make *config" checks for a file named
|
||||
"all{yes/mod/no/random}.config" (corresponding to the *config command
|
||||
that was used) for symbol values that are to be forced. If this file
|
||||
is not found, it checks for a file named "all.config" to contain forced
|
||||
values.
|
||||
|
||||
This enables you to create "miniature" config (miniconfig) or custom
|
||||
config files containing just the config symbols that you are interested
|
||||
in. Then the kernel config system generates the full .config file,
|
||||
including dependencies of your miniconfig file, based on the miniconfig
|
||||
file.
|
||||
|
||||
This 'KCONFIG_ALLCONFIG' file is a config file which contains
|
||||
(usually a subset of all) preset config symbols. These variable
|
||||
settings are still subject to normal dependency checks.
|
||||
|
||||
Examples:
|
||||
KCONFIG_ALLCONFIG=custom-notebook.config make allnoconfig
|
||||
or
|
||||
KCONFIG_ALLCONFIG=mini.config make allnoconfig
|
||||
or
|
||||
make KCONFIG_ALLCONFIG=mini.config allnoconfig
|
||||
|
||||
These examples will disable most options (allnoconfig) but enable or
|
||||
disable the options that are explicitly listed in the specified
|
||||
mini-config files.
|
||||
|
||||
KCONFIG_NOSILENTUPDATE
|
||||
--------------------------------------------------
|
||||
If this variable has a non-blank value, it prevents silent kernel
|
||||
config udpates (requires explicit updates).
|
||||
|
||||
KCONFIG_CONFIG
|
||||
--------------------------------------------------
|
||||
This environment variable can be used to specify a default kernel config
|
||||
file name to override the default name of ".config".
|
||||
|
||||
KCONFIG_OVERWRITECONFIG
|
||||
--------------------------------------------------
|
||||
If you set KCONFIG_OVERWRITECONFIG in the environment, Kconfig will not
|
||||
break symlinks when .config is a symlink to somewhere else.
|
||||
|
||||
KCONFIG_NOTIMESTAMP
|
||||
--------------------------------------------------
|
||||
If this environment variable exists and is non-null, the timestamp line
|
||||
in generated .config files is omitted.
|
||||
|
||||
KCONFIG_AUTOCONFIG
|
||||
--------------------------------------------------
|
||||
This environment variable can be set to specify the path & name of the
|
||||
"auto.conf" file. Its default value is "include/config/auto.conf".
|
||||
|
||||
KCONFIG_AUTOHEADER
|
||||
--------------------------------------------------
|
||||
This environment variable can be set to specify the path & name of the
|
||||
"autoconf.h" (header) file. Its default value is "include/linux/autoconf.h".
|
||||
|
||||
______________________________________________________________________
|
||||
menuconfig User Interface Options
|
||||
----------------------------------------------------------------------
|
||||
MENUCONFIG_MODE
|
||||
--------------------------------------------------
|
||||
This mode shows all sub-menus in one large tree.
|
||||
|
||||
Example:
|
||||
MENUCONFIG_MODE=single_menu make menuconfig
|
||||
|
||||
======================================================================
|
||||
xconfig
|
||||
--------------------------------------------------
|
||||
|
||||
Searching in xconfig:
|
||||
|
||||
The Search function searches for kernel configuration symbol
|
||||
names, so you have to know something close to what you are
|
||||
looking for.
|
||||
|
||||
Example:
|
||||
Ctrl-F hotplug
|
||||
or
|
||||
Menu: File, Search, hotplug
|
||||
|
||||
lists all config symbol entries that contain "hotplug" in
|
||||
the symbol name. In this Search dialog, you may change the
|
||||
config setting for any of the entries that are not grayed out.
|
||||
You can also enter a different search string without having
|
||||
to return to the main menu.
|
||||
|
||||
|
||||
======================================================================
|
||||
gconfig
|
||||
--------------------------------------------------
|
||||
|
||||
Searching in gconfig:
|
||||
|
||||
None (gconfig isn't maintained as well as xconfig or menuconfig);
|
||||
however, gconfig does have a few more viewing choices than
|
||||
xconfig does.

- Verbose kernel compile/build output:

Normally the kernel build system runs in a fairly quiet mode (but not

totally silent). However, sometimes you or other kernel developers need

to see compile, link, or other commands exactly as they are executed.
|

For this, use "verbose" build mode. This is done by inserting

"V=1" in the "make" command. E.g.:
