<p>Hello!  I successfully installed the dependencies on a Mac (and I've compiled programs using them so I know they work), and I even managed to install mlpack without error using cmake, however when I try to compile one of the sample programs, I get this error:</p>

<p>/usr/local/include/mlpack/core/data/serialization_shim.hpp:48:56: error: a space is required between consecutive right angle brackets (use '&gt; &gt;')<br>
            typename boost::enable_ifboost::is_class&lt;U&gt;::type*,</p>

<p>Actually, I get many errors similar to that, until it gives up and quits (fatal error: too many errors emitted, stopping now [-ferror-limit=]).  It basically dies on nearly every line in every mlpack header.</p>

<p>I googled and found very little on this, except another project that ran into a similar issue:<br>
<a href="https://github.com/symengine/symengine/issues/344" class="issue-link js-issue-link" data-url="https://github.com/symengine/symengine/issues/344" data-id="52074566" data-error-text="Failed to load issue title" data-permission-text="Issue title is private">symengine/symengine#344</a></p>

<p>I just haven't the faintest idea how to do what they did.</p>

<p>I'm presently using Clang version 7.3.0, recently downgraded from 8 because 8 breaks CUDA :-(</p>

<p>I'm willing to entertain the idea of installing gcc (or an even older Clang) if it's possible to do that without completely breaking everything that's already installed and working with Clang.  But I'm really hoping someone here has seen this before and knows what to do.</p>
