Runtime Emulator</SPAN></A></H3>

<P>The sources may be used to built two versions of the emulator. By 
default, the <EM>development emulator</EM> is built. This emulator 
contains all features for interactive development of Prolog 
applications. If the system is configured using
<STRONG>--enable-runtime</STRONG>, <STRONG>make</STRONG>(1) will create 
a
<EM>runtime version</EM> of the emulator. This emulator is equivalent to 
the development version, except for the following features:

<P>
<UL>
<LI><I>No input editing</I><BR>
The GNU library <CODE>-lreadline</CODE> that provides EMACS compatible 
editing of input lines will not be linked to the system.
<LI><I>No tracer</I><BR>
The tracer and all its options are removed, making the system a little 
faster too.
<LI><I>No profiler</I><BR>
<A NAME="idx:profile3:1520"></A><A class="pred" href="profile.html#profile/3">profile/3</A> 
and friends are not supported. This saves some space and provides better 
performance.
<LI><I>No interrupt</I><BR>
Keyboard interrupt (Control-C normally) is not rebound and will normally 
terminate the application.
<LI><I>current_prolog_flag(runtime, true) succeeds</I><BR>
This may be used to verify your application is running in the runtime 
environment rather than the development environment.
<LI><I>clause/[2,3] do not work on static predicates</I><BR>
This Prolog flag inhibits listing your program. It is only a very 
limited protection however.
</UL>

<P>The following fragment is an example for building the runtime 
environment in <CODE>\env{HOME}/lib/rt-pl-3.2.0</CODE>. If possible, the 
shared-library interface should be configured to ensure it can serve a 
large number of applications.

<PRE class="code">
% cd pl-3.2.0
% mkdir runtime
% cd runtime
% ../src/configure --enable-runtime --prefix=$HOME
% make
% make rt-install
</PRE>

<P>The runtime directory contains the components listed below. This 
directory may be tar'ed and shipped with your application.
