Although the asciidoc toolchain accepts any number of ~ to delimit a listing block (i.e. a code block), it is actually specified to be exactly four, i.e. ~~~~. Currently, a mix of diffrent numbers of ~ are being used - sometimes even a different number at the beginning and at the end of the block. Normalize this to always use exactly four ~ for the delimiter. Signed-off-by: Arnout Vandecappelle <arnout@mind.be>

=== Adding project-specific packages
|
|
|
|
In general, any new package should be added directly in the +package+
|
|
directory and submitted to the Buildroot upstream project. How to add
|
|
packages to Buildroot in general is explained in full detail in
|
|
xref:adding-packages[] and will not be repeated here. However, your
|
|
project may need some proprietary packages that cannot be upstreamed.
|
|
This section will explain how you can keep such project-specific
|
|
packages in a project-specific directory.
|
|
|
|
As shown in xref:customize-dir-structure[], the recommended location for
|
|
project-specific packages is +package/<company>/+. If you are using the
|
|
br2-external tree feature (see xref:outside-br-custom[]) the recommended
|
|
location is to put them in a sub-directory named +package/+ in your
|
|
br2-external tree.
|
|
|
|
However, Buildroot will not be aware of the packages in this location,
|
|
unless we perform some additional steps. As explained in
|
|
xref:adding-packages[], a package in Buildroot basically consists of two
|
|
files: a +.mk+ file (describing how to build the package) and a
|
|
+Config.in+ file (describing the configuration options for this
|
|
package).
|
|
|
|
Buildroot will automatically include the +.mk+ files in first-level
|
|
subdirectories of the +package+ directory (using the pattern
|
|
+package/\*/*.mk+). If we want Buildroot to include +.mk+ files from
|
|
deeper subdirectories (like +package/<company>/package1/+) then we
|
|
simply have to add a +.mk+ file in a first-level subdirectory that
|
|
includes these additional +.mk+ files. Therefore, create a file
|
|
+package/<company>/<company>.mk+ with following contents (assuming you
|
|
have only one extra directory level below +package/<company>/+):
|
|
|
|
----
|
|
include $(sort $(wildcard package/<company>/*/*.mk))
|
|
----
|
|
|
|
For the +Config.in+ files, create a file +package/<company>/Config.in+
|
|
that includes the +Config.in+ files of all your packages. An exhaustive
|
|
list has to be provided since wildcards are not supported in the source command of kconfig.
|
|
For example:
|
|
|
|
----
|
|
source "package/<company>/package1/Config.in"
|
|
source "package/<company>/package2/Config.in"
|
|
----
|
|
|
|
Include this new file +package/<company>/Config.in+ from
|
|
+package/Config.in+, preferably in a company-specific menu to make
|
|
merges with future Buildroot versions easier.
|
|
|
|
If using a br2-external tree, refer to xref:outside-br-custom[] for how
|
|
to fill in those files.
