<p>
Despite the fact the x32 psABI support is in development state for this release of the
Yocto Project, you can follow these steps to use the x32 spABI:
</p>
<div class="itemizedlist"><ul class="itemizedlist" type="disc">
<li class="listitem"><p>Add the <code class="filename">experimental/meta-x32</code> layer to your local
<a class="link" href="../dev-manual/build-directory.html" target="_self">Build Directory</a>.
You can find the <code class="filename">experimental/meta-x32</code> source repository at
<a class="ulink" href="http://git.yoctoproject.org" target="_self">http://git.yoctoproject.org</a>.</p></li>
<li class="listitem">
<p>Edit your <code class="filename">conf/bblayers.conf</code> file so that it includes
the <code class="filename">meta-x32</code>.
Here is an example:
</p>
<pre class="literallayout">
BBLAYERS ?= " \
/home/nitin/prj/poky.git/meta \
/home/nitin/prj/poky.git/meta-yocto \
/home/nitin/prj/poky.git/meta-yocto-bsp \
/home/nitin/prj/meta-x32.git \
"
</pre>
</li>
<li class="listitem">
<p>Enable the x32 psABI tuning file for <code class="filename">x86_64</code>
machines by editing the <code class="filename">conf/local.conf</code> like this:
</p>
<pre class="literallayout">
MACHINE = "qemux86-64"
DEFAULTTUNE = "x86-64-x32"
baselib = "${@d.getVar('BASE_LIB_tune-' + (d.getVar('DEFAULTTUNE', True) \
or 'INVALID'), True) or 'lib'}"
#MACHINE = "atom-pc"
#DEFAULTTUNE = "core2-64-x32"
</pre>
</li>
<li class="listitem">
<p>As usual, use BitBake to build an image that supports the x32 psABI.
Here is an example:
</p>
<pre class="literallayout">
$ bitake core-image-sato
</pre>
</li>
<li class="listitem">
<p>As usual, run your image using QEMU:
</p>
<pre class="literallayout">
$ runqemu qemux86-64 core-image-sato
</pre>
</li>
</ul></div>
<p>
</p>
</div></body>
</html>
