<p>Hi there, unfortunately I can't understand this bug report or if it is even a bug report.  Please carefully read the output of the compiler before opening issues like this, and if you do open an issue like this, please include relevant details on what you have done---it is very hard to help you out unless you provide useful information.</p>

<p>In your case I can guess that you are not compiling your program in C++11 mode because this error message is in your output:</p>

<pre><code>/usr/local/include/mlpack/core/dists/gaussian_distribution.hpp:41:16: note: C++11 ‘constexpr’ only available with -std=c++11 or -std=gnu++11
</code></pre>

<p>Please try fixing that before opening an issue here.  If that does not fix your issue, I'm not 100% sure how to help since I don't have any information on how the program was compiled, what your system information is, and so forth.  Thanks!</p>
