<p>Qt's support for different Linux platforms is extensive and mature.</p>
<a name="downloading-and-installing-qt"></a>
<h2 id="downloading-and-installing-qt">Downloading and Installing Qt</h2>
<p>There are two ways to install Qt:</p>
<ol class="1" type="1"><li>through the Qt Installers - downloads and installs Qt</li>
<li>through the <i>Qt sources</i>.</li>
</ol>
<p>You can download the Qt 5 installers and sources from the <a href="http://qt.io/download">Downloads</a> page. For more information, visit the <a href="gettingstarted.html">Getting Started with Qt</a> page.</p>
<a name="requirements-for-development-host"></a>
<h3 >Requirements for Development Host</h3>
<p>The Qt installers for Linux assume that a C++ compiler, debugger, make, and other development tools are provided by the host operating system. In addition, building graphical Qt applications requires OpenGL libraries and headers installed. Most Linux distributions do not install all of these by default, but setting up a development environment is still straightforward.</p>
<p>Use the following commands to install the basic requirements for building Qt applications:</p>
<a name="debian-ubuntu-apt-get"></a>
<h4 >Debian/Ubuntu (apt-get)</h4>
<pre class="cpp plain">

  sudo apt-get install build-essential libgl1-mesa-dev

</pre>
<a name="fedora-rhel-centos-yum"></a>
<h4 >Fedora/RHEL/CentOS (yum)</h4>
<pre class="cpp plain">

  sudo yum groupinstall &quot;C Development Tools and Libraries&quot;
  sudo yum install mesa-libGL-devel

</pre>
<a name="opensuse-zypper"></a>
<h4 >openSUSE (zypper)</h4>
<pre class="cpp plain">

  sudo zypper install -t pattern devel_basis

</pre>
<a name="building-qt-5-from-source"></a>
<h3 >Building Qt 5 from Source</h3>
<p>You can also build Qt 5 from the source package and configure it according to your target platform. The source packages are obtained from <a href="http://www.qt.io/download/">http://www.qt.io/download/</a>.</p>
<p>Below, you will find more information about building Qt from source.</p>
