<para>
<link xlink:href="http://dlib.net/">DLib</link> is a modern, C++-based toolkit which provides several machine learning algorithms.

<title>Compiling without AVX support</title>
<para>
Especially older CPUs don't support <link xlink:href="https://en.wikipedia.org/wiki/Advanced_Vector_Extensions">AVX</link> (<abbrev>Advanced Vector Extensions</abbrev>) instructions that are used by DLib to optimize their algorithms.
</para>
<para>
On the affected hardware errors like <literal>Illegal instruction</literal> will occur. In those cases AVX support needs to be disabled:
<programlisting>self: super: {
dlib = super.dlib.override { avxSupport = false; };
}</programlisting>
