The code snippet for listing AUTOREV-enabled recipes needs updating since it now inherits the "poky-bleeding" class file.

Using an External SCM
|
|
*********************
|
|
|
|
If you're working on a recipe that pulls from an external Source Code
|
|
Manager (SCM), it is possible to have the OpenEmbedded build system
|
|
notice new recipe changes added to the SCM and then build the resulting
|
|
packages that depend on the new recipes by using the latest versions.
|
|
This only works for SCMs from which it is possible to get a sensible
|
|
revision number for changes. Currently, you can do this with Apache
|
|
Subversion (SVN), Git, and Bazaar (BZR) repositories.
|
|
|
|
To enable this behavior, the :term:`PV` of
|
|
the recipe needs to include a ``+`` sign in its assignment.
|
|
Here is an example::
|
|
|
|
PV = "1.2.3+git"
|
|
|
|
:term:`Bitbake` later includes the source control information in :term:`PKGV`
|
|
during the packaging phase.
|
|
|
|
Then, you can add the following to your
|
|
``local.conf``::
|
|
|
|
SRCREV:pn-PN = "${AUTOREV}"
|
|
|
|
:term:`PN` is the name of the recipe for
|
|
which you want to enable automatic source revision updating.
|
|
|
|
If you do not want to update your local configuration file, you can add
|
|
the following directly to the recipe to finish enabling the feature::
|
|
|
|
SRCREV = "${AUTOREV}"
|
|
|
|
The Yocto Project provides a distribution named ``poky-bleeding``, whose
|
|
configuration file contains the line::
|
|
|
|
require conf/distro/include/poky-floating-revisions.inc
|
|
|
|
This line pulls in the listed include file that defines the set of
|
|
AUTOREV-enabled recipes::
|
|
|
|
INHERIT += "poky-bleeding"
|
|
|
|
POKY_AUTOREV_RECIPES = "\
|
|
libmatchbox \
|
|
opkg-utils \
|
|
matchbox-config-gtk \
|
|
matchbox-desktop \
|
|
matchbox-keyboard \
|
|
matchbox-panel-2 \
|
|
matchbox-terminal \
|
|
matchbox-theme-sato \
|
|
matchbox-wm \
|
|
pseudo \
|
|
puzzles \
|
|
sato-icon-theme \
|
|
sato-screenshot \
|
|
settings-daemon \
|
|
"
|
|
|
|
This allows you to
|
|
experiment with building a distribution that tracks the latest
|
|
development source for numerous packages.
|
|
|
|
.. note::
|
|
|
|
The ``poky-bleeding`` distribution is not tested on a regular basis. Keep
|
|
this in mind if you use it.
