 <simplesect xml:id="parallel.requirements">
  &reftitle.required;
  <para>
 parallel requires a build of PHP with ZTS (Zend Thread Safety) enabled
 (<option role="configure">--enable-zts</option>, or on non-Windows systems prior to PHP 8.0.0,
 <option role="configure">--enable-maintainer-zts</option>)
  </para>
  <caution>
  <para>
 Zend Thread Safety cannot be enabled post build; it is a build time configuration option.
  </para>
  </caution>
  <para>
 parallel should build anywhere there is a working Posix Threads header (pthread.h) and ZTS build of PHP, including Windows (using the pthread-w32 project from redhat).
  </para>

 <simplesect xml:id="parallel.installation">
  &reftitle.install;
  <para>
   parallel releases are hosted by PECL and the source code by 
    <link xlink:href="&url.git.hub;krakjoe/parallel">github</link>, 
   the easiest route to installation is the normal PECL route:
   <link xlink:href="&url.pecl.package;parallel">&url.pecl.package;parallel</link>.
  </para>
  <para>
 Windows users can download prebuilt release binaries from the <link xlink:href="&url.pecl.windows.releases;parallel">PECL</link> website.
  </para>
  <caution>
   <para>
 Windows users need to take the additional step of adding pthreadVC2.dll (distributed with Windows releases) to their <envar>PATH</envar>.
   </para>
  </caution>
