[[package-name-variable-relation]]

|
Package name, config entry name and makefile variable relationship
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
In Buildroot, there is some relationship between:
|
|
|
|
* the _package name_, which is the package directory name (and the
|
|
name of the +*.mk+ file);
|
|
|
|
* the config entry name that is declared in the +Config.in+ file;
|
|
|
|
* the makefile variable prefix.
|
|
|
|
It is mandatory to maintain consistency between these elements,
|
|
using the following rules:
|
|
|
|
* the package directory and the +*.mk+ name are the _package name_
|
|
itself (e.g.: +package/foo-bar_boo/foo-bar_boo.mk+);
|
|
|
|
* the _make_ target name is the _package name_ itself (e.g.:
|
|
+foo-bar_boo+);
|
|
|
|
* the config entry is the upper case _package name_ with `.` and `-`
|
|
characters substituted with `_`, prefixed with +BR2_PACKAGE_+ (e.g.:
|
|
+BR2_PACKAGE_FOO_BAR_BOO+);
|
|
|
|
* the +*.mk+ file variable prefix is the upper case _package name_
|
|
`.` and `-` characters substituted with `_` (e.g.:
|
|
+FOO_BAR_BOO_VERSION+).

How to add a package from github
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Packages on github often don't have a download area with release tarballs.
|
|
However, it is possible to download tarballs directly from the repository
|
|
on github.
|
|
|
|
------------------------
|
|
FOO_VERSION = v1.0 # tag or full commit ID
|
|
FOO_SITE = http://github.com/<user>/<package>/tarball/$(FOO_VERSION)
|
|
------------------------
|
|
|
|
.Notes
|
|
- The FOO_VERSION can either be a tag or a commit ID.
|
|
- The tarball name generated by github matches the default one from
|
|
Buildroot (e.g.: +foo-f6fb6654af62045239caed5950bc6c7971965e60.tar.gz+),
|
|
so it is not necessary to specify it in the +.mk+ file.
|
|
- When using a commit ID as version, you should use the full 40 hex characters.
