<p>Hi there Anukul,</p>

<p>This seems weird to me because if Armadillo is detecting SuperLU, then SuperLU should be installed.  Can you try installing SuperLU with <code>dnf install SuperLU-devel</code> and then try compiling again?</p>

<p>I will check to see that the Fedora Armadillo package (and the Fedora mlpack package) have the correct install dependencies.  I wonder if the Armadillo package has SuperLU-devel as a build requirement but not an install requirement...</p>
