<h2>Building Against Qt v5<a class="headerlink" href="#building-against-qt-v5" title="Permalink to this headline">¶</a></h2>
<p>PyQt4 can be built against Qt v5 in exactly the same way that it is built
against Qt v4. However only a Qt v4 compatible subset of Qt v5 is supported,
specifically:</p>
<ul class="simple">
<li>any classes added in Qt v5 <em>are not</em> supported</li>
<li>any new features added in Qt v5 to classes that exist in Qt v4 <em>are</em>
supported</li>
<li>any features that are marked as deprecated in Qt v5 <em>are</em> supported.</li>
</ul>
<p>The <a class="reference internal" href="installation.html#cmdoption-configure.py--no-deprecated"><em class="xref std std-option">--no-deprecated</em></a> option to PyQt4’s
<strong class="program">configure.py</strong> can be used to disable the support for the deprecated
features. This can be useful in the porting of PyQt4 applications to PyQt5.</p>
