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 reference
|
||
|
|
:term:`SRCPV`. Here is an example::
|
||
|
|
|
||
|
|
PV = "1.2.3+git${SRCPV}"
|
||
|
|
|
||
|
|
Then, you can add the following to your
|
||
|
|
``local.conf``::
|
||
|
|
|
||
|
|
SRCREV:pn-PN = "${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 = "${AUTOREV}"
|
||
|
|
|
||
|
|
The Yocto Project provides a distribution named ``poky-bleeding``, whose
|
||
|
|
configuration file contains the line::
|
||
|
|
|
||
|
|
require conf/distro/include/poky-floating-revisions.inc
|
||
|
|
|
||
|
|
This line pulls in the
|
||
|
|
listed include file that contains numerous lines of exactly that form::
|
||
|
|
|
||
|
|
#SRCREV:pn-opkg-native ?= "${AUTOREV}"
|
||
|
|
#SRCREV:pn-opkg-sdk ?= "${AUTOREV}"
|
||
|
|
#SRCREV:pn-opkg ?= "${AUTOREV}"
|
||
|
|
#SRCREV:pn-opkg-utils-native ?= "${AUTOREV}"
|
||
|
|
#SRCREV:pn-opkg-utils ?= "${AUTOREV}"
|
||
|
|
SRCREV:pn-gconf-dbus ?= "${AUTOREV}"
|
||
|
|
SRCREV:pn-matchbox-common ?= "${AUTOREV}"
|
||
|
|
SRCREV:pn-matchbox-config-gtk ?= "${AUTOREV}"
|
||
|
|
SRCREV:pn-matchbox-desktop ?= "${AUTOREV}"
|
||
|
|
SRCREV:pn-matchbox-keyboard ?= "${AUTOREV}"
|
||
|
|
SRCREV:pn-matchbox-panel-2 ?= "${AUTOREV}"
|
||
|
|
SRCREV:pn-matchbox-themes-extra ?= "${AUTOREV}"
|
||
|
|
SRCREV:pn-matchbox-terminal ?= "${AUTOREV}"
|
||
|
|
SRCREV:pn-matchbox-wm ?= "${AUTOREV}"
|
||
|
|
SRCREV:pn-settings-daemon ?= "${AUTOREV}"
|
||
|
|
SRCREV:pn-screenshot ?= "${AUTOREV}"
|
||
|
|
. . .
|
||
|
|
|
||
|
|
These lines allow 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.
