<p>Hi guys,<br>
I am trying to build mlpack under mac Marvericks over the weekend. So far I failed again and again. </p>
<p>(Again, I am sorry the quote text does not appear as I expected. I try few wikitags I learned, but non of them work for me... Sorry.)</p>
<ol>
<li><p>The library is built successfully with compiler c++ (in fact, clang, clang++), but gives a weird error in passing arguments in logistic regression, see here <a href="https://github.com/mlpack/mlpack/issues/428#issuecomment-111815633" class="issue-link" title="segmentation fault with LogisticRegression API">#428 (comment)</a></p></li>
<li><p>I suspected it was the issue of the compiler c++ that does not understand the arma::vec constructor by reference. Therefore I tried to build mlpack with gcc and g++, with all versions I have (g++-5.1, g++-mp-5, g++-mp-4.8, g++-mp-4.9), but they failed to recognise boost symbols. For example:</p></li>

<p>My armadillo is the 5.200.1.</p>

CMake Warning at CMakeLists.txt:88 (message):<br>
This is a 64-bit system, but Armadillo was compiled without 64-bit index<br>
support. Consider recompiling Armadillo with ARMA_64BIT_WORD to enable<br>
64-bit indices (large matrix support). MLPACK will still work without<br>
ARMA_64BIT_WORD defined, but will not scale to matrices with more than 4<br>
billion elements.</p>

<p>I have no idea what else to try. If you can give me some hint, it would be great. I am very grateful.</p>
<p>PS: Thanhk you for your project. I really like the name mlpack, perhaps because I am also a fan of lapack.</p>
