EPICS Release base 3.14.0alpha2</h1></center>
|
|
Since the alpha1 release some major changes were made to the build system,
|
|
to some of the libCom facilities, and to the iocsh facilities.
|
|
<p>The unbundled version of the sequencer has been build and tested with
|
|
this release. You must obtain a version of the sequencer that has been
|
|
built against alpha2.
|
|
<p>A verion of the HPlanGpib support has been built and tested with this
|
|
release. Again you must obtain a version that builds with alpha2.
|
|
<p>A new update to the Application Developer's Guide is available for this
|
|
release.
|
|
<h3>
|
|
Build changes</h3>
|
|
|
|
<ul>
|
|
<li>
|
|
Operating system independant builds are now done in an O.Common subdirectory
|
|
and then installed instead of being performed directly in an install directory.</li>
|
|
|
|
<li>
|
|
Build definition names (e.g. RECTYPES, MENUS, DBDNAME, and BPTS) have been
|
|
changed to specify the name of the file to be created and installed instead
|
|
of the source file name.</li>
|
|
|
|
<li>
|
|
All db and dbd related definitions and rules have been moved into base/configure/RULES.Db
|
|
file. The rules now allow multiple dbd files and registerRecordDeviceDriver
|
|
files to be created in a single Makefile.</li>
|
|
|
|
<li>
|
|
"gnumake depends" no longer depends on a complete buildInstall.</li>
|
|
</ul>
|
|
|
|
<h3>
|
|
Converting alpha1 applications to alpha2</h3>
|
|
Build modifications in alpha2 require the following changes to existing
|
|
R3.14 applications.
|
|
<ul>
|
|
<li>
|
|
Remove the now unused RULES files</li>
|
|
|
|
<li>
|
|
</li>
|
|
|
|
<ul>./configure/RULES.Db
|
|
<br>./configure/RULES.registerRecordDeviceDriver
|
|
<br> </ul>
|
|
|
|
<li>
|
|
Delete the following line in ./configure/RULES</li>
|
|
|
|
<ul>
|
|
<br>include $(TOP)/configure/RULES.registerRecordDeviceDriver</ul>
|
|
</ul>
|
|
|
|
<ul>
|
|
<li>
|
|
In <top>/configure/Makefile change</li>
|
|
|
|
<ul>
|
|
<br>@$(PERL) $(TOOLS)/makeConfigAppInclude.pl $(T_A) $@ $(TOP)</ul>
|
|
to
|
|
<ul>@$(PERL) $(TOOLS)/makeConfigAppInclude.pl $(EPICS_HOST_ARCH) $(T_A)
|
|
$@ $(TOP)
|
|
<br> </ul>
|
|
and add the line
|
|
<ul>
|
|
<br>depends: install
|
|
<br> </ul>
|
|
to the bottom of the Makefile.
|
|
<ul> </ul>
|
|
</ul>
|
|
|
|
<ul>
|
|
<li>
|
|
In all *App/*Db/Makefileschange</li>
|
|
|
|
<ul>
|
|
<br>include $(TOP)/configure/RULES.Db</ul>
|
|
to
|
|
<ul>include $(TOP)/configure/RULES</ul>
|
|
|
|
<li>
|
|
In all *App/src/Makefile files</li>
|
|
|
|
<ul> </ul>
|
|
change DBDNAME = <name>App to
|
|
DBD += <name>
|
|
<ul> </ul>
|
|
and remove the line
|
|
<br>
|
|
<ul>DBDEXPAND = <name>Include.dbd
|
|
<br> </ul>
|
|
NOTE: If any of your *App/*Db/Makefiles contain "DBDNAME =" lines you should
|
|
make these same changes in that *Db dirctory.
|
|
<br>
|
|
<li>
|
|
In all *App/src/Makefile Makefiles</li>
|
|
|
|
<ul> </ul>
|
|
change RECTYPES=<name>.h to
|
|
DBDINC+=<name>
|
|
<ul> </ul>
|
|
change MENUS=<name>.h to
|
|
DBDINC+=<name></ul>
|
|
|
|
<ul>change BPTS to

<p>change INSTALLDB to
|
|
DB
|
|
<p>change DBDINSTALL to
|

In all example *App/src/Makefile files change</li>

|
|
to
|
|
<ul>example_SRCS_DEFAULT += <name>_registerRecordDeviceDriver.cpp
|
|
<br> </ul>
|
|
where <name> is the base name of a <name>.dbd file which was created
|
|
from a <name>Include.dbd file and which will be loaded in a st.cmd or
|
|
stcmd.host script (e.g. example).
|
|
<br>
|
|
<li>
|
|
In ./iocBoot/ioc<name>/st.cmd files change</li>
|
|
|
|
<br>
|
|
<ul>dbLoadDatabase("dbd/exampleApp.dbd")</ul>
|
|
to
|
|
<ul>dbLoadDatabase("dbd/example.dbd")
|
|
<br> </ul>
|
|
|
|
<li>
|
|
In <top>/iocBoot/ioc<name>/stcmd.host files change</li>
|
|
|
|
<ul>

|
|
</ul>
|

<h3>
|
|
EPICS_HOST_ARCH changes</h3>
|
|
GNU compiler builds are now determined by the value of EPICS_HOST_ARCH
|
|
and are no longer specified in CONFIG_SITE. All references to the
|
|
ANSI (ACC/GCC) and CPLUSPLUS (CCC/G++) macros have been removed.
|
|
<br>
|
|
<h3>
|
|
libCom</h3>
|
|
Most of the library routines and files starting with the prefix osi have
|
|
been changed to start with epics. Several also had major changes to their
|
|
user interface. See the latest version of the Application Developer's Guide
|
|
for details.

|
|
gives links to the new Application Developer's Guide and to RTEMS information.
|
|
<p>http://www.aps.anl.gov/epics/modules/base/R3-14.php
|
|
<p>Most of the Application Developer's Guide has only minor changes. The
|
|
following are new.
|
|
<ul>
|
|
<li>
|
|
Chapter 2 describes the new features for 3.14.</li>
|
|
|
|
<li>
|
|
Chapter 4 describes the build facility for 3.14</li>
|
|
|
|
<li>
|
|
Chapters 19 and 20 describe libCom, which was not previously documented.</li>
|
|
</ul>
|
|
|
|
<p><br>It must be emphasized that this is an alpha release.
|
|
<ul>
|
|
<li>
|
|
Please don't use it for existing operational systems</li>
|
|
|
|
<li>
|
|
Don't build your operational CA clients with it.</li>
|
|
|
|
<li>
|
|
The APIs for new components in libCom are still evolving so if you use
|
|
them be prepared for changes.</li>
|
|
|
|
<li>
|
|
HPUX - No support currently because we could not find good support for
|
|
multithreading.</li>
|
|
</ul>
|
|
Building Applications
|
|
<ul>
|
|
<li>

|
|
Facility) of the Application Developer's Guide.</li>
|
|
|
|
<li>

For existing applications the old config rules are still supported. Some
|
|
changes, however, are needed. Documentation is being prepared and will
