make</userinput></screen>

    <para>To test the results, issue: <command>make check</command>.
    Owing to various reports of mis-compilations, the maintainer strongly
    recommends running the test-suite and report any failures. The libraries
    should not be used in a production environment if there are problems
    running <command>make check</command>.</para>
