<span class="subtitle"></span>
<!-- $$$linux-issues.html-description -->
<div class="descr"> <a name="details"></a>
<p>This page contains information about the X11 platforms Qt is currently known to run on, with links to platform-specific notes.</p>
<a name="linux"></a>
<h2 id="linux">Linux</h2>
<p>There are no known problems with using Qt on production versions of Linux/x86, Linux/ppc, Linux/amd64 and Linux/ia64 (including Altix(R)).</p>
<p>For information about the specific compilers supported, visit the <a href="supported-platforms.html#reference-configurations">supported platforms</a> page.</p>
<a name="installation-problems"></a>
<h3 >Installation problems</h3>
<p>Installing the source (<i>.tgz</i>) will likely conflict with the Qt version from your Linux distribution. This can result in link errors, such as:</p>
<pre class="cpp">
undefined reference to <span class="char">'_vt.11QPushButton'</span>
</pre>
<p>This is solved by removing the older version of the library.</p>
<p>If you have problems installing open source versions of Qt provided by your Linux distribution, for example, from RPM or APT repositories, please consult the maintainers of the distribution.</p>
<p>Some RPM versions have problems installing some of the Qt RPM archives where installation stops with an error message warning about a <b>Failed Dependency</b>. Use the <code>--nodeps</code> option of <code>rpm</code> as workaround this problem.</p>
<a name="intel-c-compiler-for-linux"></a>
<h3 >Intel C++ Compiler for Linux</h3>
<p>Qt can be compiled with the Intel C++ compile for Linux, though, this configuration is not tested on a regular basis.</p>
<a name="known-issues-with-intel-c-compiler-for-linux"></a>
<h3 >Known Issues with Intel C++ Compiler for Linux</h3>
<ul>
<li>Precompiled header support does not work in version 10.0.025 and older. For these compilers, you should configure Qt with -no-pch. Precompiled header support works properly in version 10.0.026 and later.</li>
<li>Version 10.0.026 for Intel 64 is known to miscompile qmake when building in release mode. For now, configure Qt with -debug. Version 10.1.008 and later can compile qmake in release mode.</li>
<li>Versions 10.1.008 to 10.1.015 for both IA-32 and Intel 64 are known crash with "(0): internal error: 0_47021" when compiling Qt XML Patterns and <a href="../qtdesigner/qtdesigner-manual.html">Qt Designer</a> in release mode. Version 10.1.017 compiles these modules correctly in release mode.</li>
</ul>
<a name="known-issues-with-gcc-compilers"></a>
<h3 >Known Issues with GCC Compilers</h3>
<p>Building Qt with certain versions of GCC has the following known issues:</p>
<ul>
<li>GCC 4.9.2 fails to build Qt:<ul>
<li><a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65309">Related bug</a> in GCC's bug tracker</li>
<li><a href="http://lists.qt-project.org/pipermail/development/2015-March/020632.html">Discussion</a> on <a href="mailto://development@qt-project.org">development@qt-project.org</a> mailing list</li>
</ul>
</li>
<li>GCC 5.2.1: Nested structs do not get their constructors called under some circumstances:<ul>
<li><a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67550">Related bug</a> in GCC's bug tracker</li>
