Up to <em>calc</em> release R2-6 (<em>synApps</em> release R5_1),
the <em>scalcout</em> record needs a fix.
(See separate <a href="scalcout.html"><em>scalcout</em> page</a>.)
Support for the scalcout is optional. <em>StreamDevice</em> works
as well without scalcout or SynApps.

Make sure that the <em>asyn</em> library (and the <em>calc</em> module of
<em>synApps</em>, if desired) can be found, e.g. by
adding <code>ASYN</code>
and (if installed) <code>CALC</code> or <code>SYNAPPS</code>
to your <kbd>&lt;top&gt;/configure/RELEASE</kbd> file:
</p>
<pre>
ASYN=/home/epics/asyn/4-5

If you want to enable regular expression matching, you need the <em>PCRE</em> package.
For most Linux systems, it is already installed. In that case add the locations
of the <em>PCRE</em> header and library to your <kbd>RELEASE</kbd> file:
</p>
<pre>
PCRE_INCLUDE=/usr/include/pcre
PCRE_LIB=/usr/lib
</pre>
<p>
If you want to build <em>StreamDevice</em> for platforms without <em>PCRE</em> support,
it is the easiest to build <em>PCRE</em> as an EPICS application.
Download the <em>PCRE</em> package from <a target=ex href="http://www.pcre.org">www.pcre.org</a>
and compile it with my EPICS compatible
<a target=ex href="http://epics.web.psi.ch/software/streamdevice/pcre/Makefile">Makefile</a>.
Then define the location of the application in your RELEASE file.

Regular expressions are optional. If you don't want them, you don't need this.
