Environment variables
|
|
|
|
KCPPFLAGS
|
|
--------------------------------------------------
|
|
Additional options to pass when preprocessing. The preprocessing options
|
|
will be used in all cases where kbuild does preprocessing including
|
|
building C files and assembler files.
|
|
|
|
KAFLAGS
|
|
--------------------------------------------------
|
|
Additional options to the assembler (for built-in and modules).
|
|
|
|
AFLAGS_MODULE
|
|
--------------------------------------------------
|
|
Additional module specific options to use for $(AS).
|
|
|
|
AFLAGS_KERNEL
|
|
--------------------------------------------------
|
|
Additional options for $(AS) when used for assembler
|
|
code for code that is compiled as built-in.
|
|
|
|
KCFLAGS
|
|
--------------------------------------------------
|
|
Additional options to the C compiler (for built-in and modules).
|
|
|
|
CFLAGS_KERNEL
|
|
--------------------------------------------------
|
|
Additional options for $(CC) when used to compile
|
|
code that is compiled as built-in.
|
|
|
|
CFLAGS_MODULE
|
|
--------------------------------------------------
|
|
Additional module specific options to use for $(CC).
|
|
|
|
LDFLAGS_MODULE
|
|
--------------------------------------------------
|
|
Additional options used for $(LD) when linking modules.
|
|
|
|
KBUILD_VERBOSE
|
|
--------------------------------------------------
|
|
Set the kbuild verbosity. Can be assigned 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) Environment variable KBUILD_EXTMOD
|
|
3) Environment 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 specified using "O=...".
|
|
Setting "O=..." takes precedence over KBUILD_OUTPUT.
|
|
|
|
KBUILD_DEBARCH
|
|
--------------------------------------------------
|
|
For the deb-pkg target, allows overriding the normal heuristics deployed by
|
|
deb-pkg. Normally deb-pkg attempts to guess the right architecture based on
|
|
the UTS_MACHINE variable, and on some architectures also the kernel config.
|
|
The value of KBUILD_DEBARCH is assumed (not checked) to be a valid Debian
|
|
architecture.
|
|
|
|
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 in some setups.
|
|
|
|
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.
|
|
|
|
INSTALLKERNEL
|
|
--------------------------------------------------
|
|
Install script called when using "make install".
|
|
The default name is "installkernel".
|
|
|
|
The script will be called with the following arguments:
|
|
$1 - kernel version
|
|
$2 - kernel image file
|
|
$3 - kernel map file
|
|
$4 - default install path (use root directory if blank)
|
|
|
|
The implementation of "make install" is architecture specific
|
|
and it may differ from the above.
|
|
|
|
INSTALLKERNEL is provided to enable the possibility to
|
|
specify a custom installer when cross compiling a kernel.
|
|
|
|
KBUILD_EXTRA_SYMBOLS
|
|
--------------------------------------------------
|
|
For modules that use symbols from other modules.
|
|
See more details in modules.txt.
|
|
|
|
KBUILD_ENABLE_EXTRA_GCC_CHECKS
|
|
--------------------------------------------------
|
|
If enabled over the make command line with "W=1", it turns on additional
|
|
gcc -W... options for more extensive build-time checking.
|
|
|
|
KBUILD_BUILD_TIMESTAMP
|
|
--------------------------------------------------
|
|
Setting this to a date string overrides the timestamp used in the
|
|
UTS_VERSION definition (uname -v in the running kernel). The value has to
|
|
be a string that can be passed to date -d. The default value
|
|
is the output of the date command at one point during build.
