<h4>Path for Cap5 loadable library changed</h4>
|
||||
|
||||
<p>The perl CA module makes use of a loadable library, which used to be loaded
|
||||
from the base/lib/<host-arch> directory. However different versions of
|
||||
Perl require different loadable library binaries as the Perl ABI can change.
|
||||
Now the library will be installed into and loaded from the directory
|
||||
base/lib/perl/<version>/<archname> where both <version> and
|
||||
<archname> are taken from the Perl configuration. This makes it possible
|
||||
for the same Perl script to be run on both RHEL5 and RHEL6 workstations say, even
|
||||
though they use different versions of Perl.</p>
|
||||
|
||||
<p>To achieve that, first build EPICS Base using the older OS version. Then
|
||||
on a machine running the newer version, go into the base/src/cap5 directory and
|
||||
run a <tt>make rebuild</tt> command. This will rebuild the libCap5.so file and
|
||||
install it into the location appropriate for its Perl version and architecture.</p>
|
||||
|
||||
<h4>Build configurations updated for Apple iOS targets</h4>
|
||||
|
||||
<p>The build process can now construct universal binaries containing both ARMv6
|
||||
and ARMv7 code, and several defaults have been changed when building for iOS
|
||||
targets:</p>
|
||||
|
||||
<ul>
|
||||
|
||||
<li>The default value for IOS_VERSION is now 5.0, edit the setting in
|
||||
<tt>configure/os/CONFIG_SITE.Common.iosCommon</tt> to use an older version.</li>
|
||||
|
||||
<li>With the introduction of iOS 5.0 we have switched the C++ compiler for
|
||||
ios-arm from GNU g++ to using the LLVM-based clang++ (the GNU compilers are
|
||||
apparetnly no longer included with the SDK). This can be switched back by
|
||||
editing the new <tt>CONFIG_SITE.Common.ios-arm</tt> file.</li>
|
||||
|
||||
<li>Like the Darwin builds, universal binaries can now be compiled for the
|
||||
ios-arm target, containing either or both ARMv6 and ARMv7 instructions. This is
|
||||
configured by setting ARCH_CLASS in the new <tt>CONFIG_SITE.Common.ios-arm</tt>
|
||||
file. The default is now to build for ARMv7 only, which is not compatible with
|
||||
the original iPhone 1 or 3G, or with the iPod Touch Generations 1 or 2.</li>
|
||||
|
||||
</ul>
|
||||
|
||||
<h4>Added <tt>-b</tt> option to dbExpand</h4>
|
||||
|
||||
<p>This turns off monotonic checking of breakpoint tables.</p>

<h4>Added database sanity checks to iocInit</h4>
|
||||
|
||||
<p>Two menus may legitimately be modified by users; some checks have been added
|
||||
that run at iocInit and make sure the choices haven't been changed too much for
|
||||
the IOC to function properly:</p>
|
||||
|
||||
<ul>
|
||||
<li><tt>menuConvert</tt> is checked to flag problems with IOCs converted from
|
||||
3.13.x, where the SLOPE choice didn't exist.</p>
|
||||
<li><tt>menuScan</tt> is checked to ensure the three initial choices are still
|
||||
present and that there is at least one periodic scan rate.</li>
|
||||
</ul>
|
||||
|
||||
<h4>Fix various catools issues</h4>
|
||||
|
||||
<p>Array handling in the caget and camonitor programs has been debugged, fixing
|
||||
<a href="https://bugs.launchpad.net/bugs/794749">launchpad bug 794749</a> along
|
||||
with a few other related issues dating back to the addition of variable length
|
||||
array support.</p>
|
||||
|
||||
<h4>Another race condition in errlog cleaned up</h4>
|
||||
|
||||
<p>If it was still busy when the IOC was closed down, the errlog thread could
|
||||
have preempted the exit handler and freed the various internal pvtData mutex and
|
||||
event objects too soon.</p>
|
||||
|
||||
<h4>Top-level make target changes</h4>
|
||||
|
||||
<p>Several make targets have been changed. Note that these can only be used from
|
||||
an application's <top> directory.</p>
|
||||
|
||||
<dl>
|
||||
<dt><code>make uninstall.<arch></code></dt>
|
||||
<dd>Deletes the bin/<arch> and lib/<arch> directories for
|
||||
<arch> only. Note that <arch> does not have to be an
|
||||
architecture that this host is configured to build, it works for any
|
||||
arch.</dd>
|
||||
|
||||
<dt><code>make archuninstall</code></dt>
|
||||
<dd>Deletes the bin/<arch> and lib/<arch> directories for all
|
||||
architectures that this host is configured to build. Should not affect files
|
||||
used for multiple architectures, or for host or target architectures that
|
||||
this host is not configured to build.</dd>
|
||||
|
||||
<dt><code>make uninstall</code></dt>
|
||||
<dd>Does archuninstall and also deletes the other install directories include,
|
||||
db, dbd, doc, html, templates and java. This will affect subsequent builds
|
||||
for other architectures, but it doesn't delete their bin/<arch> or
|
||||
lib/<arch> contents.</dd>
|
||||
|
||||
<dt><code>make realuninstall</code></dt>
|
||||
<dd>Deletes all install directories for all architectures.</dd>
|
||||
|
||||
<dt><code>make distclean</code></dt>
|
||||
<dd>Does realclean realuninstall as before, and also now does a cvsclean,
|
||||
which removes file remnants from CVS operations named <code>.#*</code> and
|
||||
editor backups named <code>*~</code> throughout the source tree.</dd>
|
||||
|
||||
</dl>
|
||||
|
||||
<h4>Compress record type</h4>
|
||||
|
||||
<p>This record now posts monitors on its NUSE field whenever its value changes.
|
||||
A new field OUSE was added to support this.</p>
|
||||
|
||||
<h4>Remove C++ build rule for <code>.C</code> files</h4>
|
||||
|
||||
<p>An early convention on Unix systems was to name C++ files with an upper-case
|
||||
extention, <code>.C</code>. This does not work on Windows or MacOS where the
|
||||
filesystems are case-insensitive, and the C++ build rule was causing problems so
|
||||
has been eliminated. Any remaining C++ source files that are still using this
|
||||
convention will have to be renamed, preferably to <code>.cpp</code></p>
|
||||
|
||||
<h4>Support <code>make -s</code> on Windows</h4>
|
||||
|
||||
<p>The flag to silence build output did not work on some Windows architecture
|
||||
combinations. This has now been fixed.</p>
|
||||
|
||||
<h4>iocLogServer now supports logrotate</h4>
|
||||
|
||||
<p>The feature in the iocLogServer that closed and reopened the logfile used to
|
||||
ignore the SIGHUP signal when the log filename did not change. This has now been
|
||||
changed so these logfiles can be used with the standard Linux logrotate
|
||||
package.</p>
