Compiling Apache under UnixWare

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.

UnixWare 1.x

Make sure that USE_FCNTL_SERIALIZE_ACCEPT is defined (if not defined by Apache autoconfiguration). If using the UnixWare cc compiler, and you still see accept() errors, don't use compiler optimization, or get gcc.

UnixWare 2.0.x

SCO patch tf2163 is required in order for Apache to work correctly on UnixWare 2.0.x. See http://www.sco.com for UnixWare patch information.

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).

UnixWare 2.1.x

SCO patch ptf3123 is required in order for Apache to work correctly on UnixWare 2.1.x. See http://www.sco.com for UnixWare patch information.

NOTE: Unixware 2.1.2 and later already have patch ptf3123 included

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).
