<p>Homebrew installed Armadillo does not have this problem, because in <code>include/armadillo_bits/config.hpp</code> it has:</p>

<pre><code>#if defined(ARMA_USE_WRAPPER)
  #if defined(ARMA_USE_CXX11)
    #if !defined(ARMA_USE_EXTERN_CXX11_RNG)
/* #undef ARMA_USE_EXTERN_CXX11_RNG */
    #endif
  #endif
#endif
</code></pre>

<p>I don't know how does Homebrew do this, since I follow the same procedure to build Armadillo.</p>
