<p>We are currently allowing a subset of C++11 to be used in Cactus and the Einstein Toolkit. Looking at configure.in the supported features are:</p>
<ul>
<li>the auto specifier</li>
<li>C++ lambdas</li>
<li>C++ range based for</li>
</ul>
<p>To support all interesting features one would need at least icpc 15 as well as g++ 4.8 and clang 3.3.</p>
<h2 id="markdown-header-compiler-support">Compiler support</h2>
<p>The major compilers provide the following information on the features they support:</p>

<li><a data-is-external-link="true" href="http://clang.llvm.org/cxx_status.html" rel="nofollow">Features supported by clang compilers</a></li>
</ul>
<p>This summarizes the specific C++11 <strong>language</strong> features.</p>
