Converting an EPICS R3.13 application to R3.14.0.beta1</h2></center>
|
|
|
|
<p><br>This document describes how to convert a R3.13 vxWorks application
|
|
so that it builds with release R3.14.0beta1. It describes procedures
|
|
such that:
|
|
<ul>
|
|
<li>
|
|
The application uses the configure rules which are new to R3.14.</li>
|
|
</ul>
|
|
|
|
<ul>
|
|
<li>
|
|
The OSI (Operating System Independent) features of R3.14 are available,
|
|
i.e. iocCore products can be build for vxWorks as well as other platforms,
|
|
e.g. solaris and linux.</li>
|
|
</ul>

Gnumake clean uninstall</h3>

directory to remove all files created by earlier builds.</blockquote>

<h3>

Record support changes</h3>
|
|
|
|
<blockquote>The steppermotor, scan, and pid records are no longer in base.
|
|
If these records are not used in your application, comment out references
|
|
to them in base.dbd. If these record types are used at your site, they
|
|
should be downloaded and built with base R3.14 by your EPICS administrator.
|
|
To update the R3.14 location of these record types in your application
|
|
you must add appropriate module definitions to your application's
|
|
config/RELEASE file and change the <tt>LIBOBJS</tt> definitions.
|
|
<p>For example add</blockquote>
|
|
|
|
<blockquote> <tt>PID=<full
|
|
path to modules directory>/pid</tt>
|
|
<p>to config/RELEASE.
|
|
<br>Remove</blockquote>
|
|
|
|
<blockquote> <tt>LIBOBJS
|
|
+= $(EPICS_BASE_BIN)/pidRecord.o</tt>
|
|
<p>from baseLIBOBJS, and add</blockquote>
|
|
|
|
<blockquote>
|
|
<blockquote><tt>LIBOBJS += $(PID_BIN)/pidRecord.o</tt></blockquote>
|
|
to your application src/Makefile.</blockquote>
|
|
|
|
<blockquote>You should consider changing any existing old steppermotor
|
|
records to the new EPICS motor record module supported by Beamline
|
|
Controls and Data Acquisition at APS.</blockquote>
|
|
|
|
<h3>
|
|
RecDynLink.o and devPtSoft changes</h3>
|
|
|
|
<blockquote>recDynLink.o and devPtSoft.o are no longer in EPICS base and
|
|
now exist as separate EPICS modules.You must now add the appropriate module
|
|
full path definitions to your application config/RELEASE file, and change
|
|
<tt>LIBOBJS</tt>
|
|
location definition <tt>$(EPICS_BASE_BIN)</tt> to the module definition
|
|
bin directory in your application src directory files. See "Hardware
|
|
support changes" below for instructions.</blockquote>
|
|
|
|
<h3>
|
|
Hardware support changes</h3>
|
|
|
|
<blockquote>All hardware support (dev, drv and dbd files) except soft support
|
|
has been unbundled from base R3.14. This support includes the files symb.dbd,
|
|
drvHp1404a.o, drvEpvxiMsg.o, and drvEpvxi.o. If these are not used by your
|
|
application, comment out references to them in base.dbd.</blockquote>

<blockquote>Hardware support now exists as separate EPICS modules. The

hardware support for your site should be downloaded and built with base

<tt>LIBOBJS</tt>

<h3>

dbLoadtemplate tool changes</h3>

|
<blockquote>The host tool dbLoadTemplate has been replace by a new EPICS

|
extension, msi, which should be downloaded and built with base R3.14 by
|
|
your EPICS administrator. dbLoadTemplate is still supported on iocs.
|
|
If, in your application, db files are created from template and substitution
|
|
files you should add the definition
|
|
<p> <tt>EPICS_EXTENSIONS=<full
|
|
path name to epics extensions directory></tt>

<p>to your application config/RELEASE file.</blockquote>
