<title>Threading libraries</title>
<para>The threading library must be linked to the binaries
using a special linker flag <literal>-pthread</literal> on
&os;. If a port insists on linking
<literal>-lpthread</literal> or <literal>-lc_r</literal>
directly, patch it to use <makevar>PTHREAD_LIBS</makevar>
variable provided by the ports framework. This variable
usually has the value of <literal>-pthread</literal>, but
on certain architectures and &os; versions it can have
different values, so do not just hardcode
<literal>-pthread</literal> into patches and always use
<makevar>PTHREAD_LIBS</makevar>.</para>
