<h1 align="CENTER">Compiling Apache under UnixWare</h1>
To compile a working copy of Apache under UnixWare, there are
several other steps you may need to take. These prevent such
problems as zombie processes, bind errors, and accept errors,
to name a few.
<h2>UnixWare 1.x</h2>
Make sure that USE_FCNTL_SERIALIZE_ACCEPT is defined (if not
defined by Apache autoconfiguration). If using the UnixWare
<em>cc</em> compiler, and you still see accept() errors, don't
use compiler optimization, or get <em>gcc</em>.
<h2>UnixWare 2.0.x</h2>
SCO patch <a
href="ftp://ftp.sco.com/UW20/tf2163.txt">tf2163</a> is required
in order for Apache to work correctly on UnixWare 2.0.x. See <a
href="http://www.sco.com">http://www.sco.com</a> for UnixWare
patch information.
<p>In addition, make sure that USE_FCNTL_SERIALIZE_ACCEPT is
defined (if not defined by Apache autoconfiguration). To reduce
instances of connections in FIN_WAIT_2 state, you may also want
to define NO_LINGCLOSE (Apache 1.2 only).</p>
<h2>UnixWare 2.1.x</h2>
SCO patch <a
href="ftp://ftp.sco.com/UW21/ptf3123b.txt">ptf3123</a> is
required in order for Apache to work correctly on UnixWare
2.1.x. See <a href="http://www.sco.com">http://www.sco.com</a>
for UnixWare patch information.
<p><strong>NOTE:</strong> Unixware 2.1.2 and later already have
patch ptf3123 included</p>
<p>In addition, make sure that USE_FCNTL_SERIALIZE_ACCEPT is
defined (if not defined by Apache autoconfiguration). To reduce
instances of connections in FIN_WAIT_2 state, you may also want
to define NO_LINGCLOSE (Apache 1.2 only).</p>

builds.</p>
