BitBake also contains a set of "fetcher" modules that allow
|
|||
|
|
retrieval of source code from various types of sources.
|
|||
|
|
For example, BitBake can get source code from a disk with the metadata, from websites,
|
|||
|
|
from remote shell accounts or from Source Code Management (SCM) systems
|
|||
|
|
like <code class="filename">cvs/subversion/git</code>.
|
|||
|
|
</p>
|
|||
|
|
<p>
|
|||
|
|
Fetchers are usually triggered by entries in
|
|||
|
|
<code class="filename"><a class="link" href="ref-variables-glos.html#var-SRC_URI" title="SRC_URI">SRC_URI</a></code>.
|
|||
|
|
You can find information about the options and formats of entries for specific
|
|||
|
|
fetchers in the BitBake manual located in the
|
|||
|
|
<code class="filename">bitbake/doc/manual</code> directory of the
|
|||
|
|
<a class="link" href="../dev-manual/source-directory.html" target="_self">Source Directory</a>.
|
|||

One useful feature for certain Source Code Manager (SCM) fetchers is the ability to
|
|||
|
|
"auto-update" when the upstream SCM changes version.
|
|||
|
|
Since this ability requires certain functionality from the SCM, not all
|
|||
|
|
systems support it.
|
|||
|
|
Currently Subversion, Bazaar and to a limited extent, Git support the ability to "auto-update".
|
|||
|
|
This feature works using the <code class="filename"><a class="link" href="ref-variables-glos.html#var-SRCREV" title="SRCREV">SRCREV</a></code>
|
|||
|
|
variable.
|
|||
|
|
See the
|
|||
|
|
"<a class="link" href="../dev-manual/platdev-appdev-srcrev.html" target="_self">Using an External SCM</a>" section
|
|||
|
|
in the Yocto Project Development Manual for more information.
