+
+<h3><a name="Required1" id="Required1">Required Header (.h) Files</a></h3>
+
+<p>An application that uses the CA client library functions described in this
+document will need to include the cadef.h header files as follows.</p>
+
+<p><code>#include "cadef.h"</code></p>
+
+<p>This header file is located at "&lt;EPICS base&gt;/include/". It includes
+many other header files (operating system specific and otherwise), and
+therefore the application must also specify "&lt;EPICS
+base&gt;/include/os/&lt;arch&gt;" in its header file search path.</p>
+
+<h3><a name="Required" id="Required">Required Libraries</a></h3>
+
+<p>An application that uses the CA client library functions described in this
+document will need to link with the EPICS CA Client Library and also the
+EPICS Common Library. The EPICS CA Client Library calls the EPICS Common
+Library. The following table shows the names of these libraries on UNIX and
+Windows systems.</p>

+<h3><a name="Compiler" id="Compiler">Compiler and System Specific Build
+Options</a></h3>
+
+<p>If you do not use the EPICS build environemnt (layered make files) then it
+may be helpful to run one of the EPICS make files and watch the compile/link
+lines. This may be the simplest way to capture the latest system and compiler
+specific options required by your build environment. I have included some
+snapshots of typical build lines below, but expect some risk of this
+information becoming dated.</p>
