An 'include' directory is automatically created inside INSTALL_HDR_PATH and

headers are installed in 'INSTALL_HDR_PATH/include'.

|

The command "make headers_install_all" exports headers for all architectures

simultaneously. (This is mostly of interest to distribution maintainers,
|

who create an architecture-independent tarball from the resulting include
|
||||
directory.) You also can use HDR_ARCH_LIST to specify list of architectures.
|
||||
Remember to provide the appropriate linux/asm directory via "mv" or "ln -s"
|

before building a C library with headers exported this way.

KBUILD_ABS_SRCTREE
|
||||
--------------------------------------------------
|
||||
Kbuild uses a relative path to point to the tree when possible. For instance,
|
||||
when building in the source tree, the source tree path is '.'
|
||||
|
||||
Setting this flag requests Kbuild to use absolute path to the source tree.
|
||||
There are some useful cases to do so, like when generating tag files with
|
||||
absolute path entries etc.

In this example, extra-y is used to list object files that

shall be built, but shall not be linked as part of built-in.a.
|
||||
|
||||
header-test-y
|
||||
|
||||
header-test-y specifies headers (*.h) in the current directory that
|
||||
should be compile tested to ensure they are self-contained,
|
||||
i.e. compilable as standalone units. If CONFIG_HEADER_TEST is enabled,
|
||||
this builds them as part of extra-y.
|
||||
|
||||
header-test-pattern-y
|
||||
|
||||
This works as a weaker version of header-test-y, and accepts wildcard
|
||||
patterns. The typical usage is:
|
||||
|
||||
header-test-pattern-y += *.h
|
||||
|
||||
This specifies all the files that matches to '*.h' in the current
|
||||
directory, but the files in 'header-test-' are excluded.
