<h2>Device Support, which does not implement special_linconv, is broken</h2>
|
|
<p>In release beta1 changes were made to allow ESLO EOFF to be
|
|
database design fields. Because of changes that were made to aiRecord and
|
|
aoRecord device support that does not implement special_linconv
|
|
may no longer work.<p>
|
|
<p>To fix aiRecord.c, in init_record replace</p>
|

<pre> if ((pai->linr == menuConvertLINEAR) && pdset->special_li
|

<h2>CA puts to disabled record</h2>
|
|
<p>If a CA client issues a put to a disabled record then, when the record is ena
|
|
bled, database puts to the record will not make the record process until a CA pu
|
|
t is again issued. The fix is:</p>

<h2>config - Old build rules</h2>
|
|
|
|
<p>The following files should be added in the base/config directory to allow
|
|
builds of R3.13 (Makefile.Host) extensions with beta1.</p>
|
|
<pre>win32-x86-borland builds need:
|
|
File name: CONFIG.Host.win32-x86-borland
|
|
File contents: -include $(EPICS_BASE)/config/CONFIG.Host.Borland
|
|
File name: CONFIG_HOST_ARCH.win32-x86-borland
|
|
File contents: -include $(EPICS_BASE)/config/CONFIG_HOST_ARCH.Borland
|
|
File name: CONFIG_SITE.Host.win32-x86-borland
|
|
File contents: -include $(EPICS_BASE)/config/CONFIG_SITE.Host.Borland
|
|
|
|
hpux-m68k builds need:
|
|
File name: CONFIG.Host.hpux-m68k
|
|
File contents: -include $(EPICS_BASE)/config/CONFIG.Host.hp700
|
|
File name: CONFIG_HOST_ARCH.hpux-m68k

<h2>configure - New build rules</h2>
|
|
|
|
<p>The following change is needed for shared library builds on Unix hosts.</p>
|
|
<pre>Index: CONFIG_BASE
|
|

<h2>vxWorks TIMEZONE pentium</h2>
|
|
|
|
<p>If the name of the timezone has more than a few characters a crash can
|
|
occur on pentium vxWorks iocs. See ansiTime in the vxWorks reference manual
|
|
for details about TIMEZONE.</p>
|
|
|
|
<h2>epicsReadLine</h2>
|
|
|
|
<p>src/libCom/osi/os/default/epicsReadline.c used a char variable to hold the
|
|
return value from getc(), and compared this against EOF. getc() returns int
|
|
not char because ANSI C allows char to be unsigned if the architecture finds
|
|
that easier, thus EOF can never be stored in a char on a PowerPC CPU. char
|
|
should be changed to int or signed char.</p>
|
|
|
|
<h2>RTEMS and NTP</h2>
|
|
|
|
<p>The RTEMS startup routine waits until a time synchronization packet is
|
|
received from an NTP server. This causes the RTEMS intialization to loop
|
|
endlessly if there is no NTP server on the network. This problem has been
|
|
fixed in the CVS version by allowing the initialization to time out after a
|
|
minute or so and to set the IOC time to January 1, 2001.</p>
