EPICS R184.108.40.206 Release Notes
Little Endian Support
Little endian support has been added to source files (dct and ? ). For little
endian architectures, "-DLITTLE_ENDIAN" should be added to the ARCH_DEP_CFLAGS
definition in the architecture specific CONFIG file (e.g. CONFIG.Unix.alpha).
Compumotor 1830 Driver
The calling sequence for compu_driver in the compumotor driver source code has
been updated to match the call in the compumotor device source code.
The proper calling sequence is now:
compu_driver(card, channel, value_flag,arg1,arg2).
Previously the channel parameter was missing.
Pentek high speed ADC device support
The Pentek high speed ADC device support had a bug that was corrected.
Only one card could exist in the IOC at a time.
Time Stamp Driver Changes
Changes to base/src/db/drvTS.c and base/include/drvTS.h, the time stamp
driver. Here is a summary of the changes made.
Added ability to get high resolution time stamps (for the current time).
Currently event 0 is the current time, updated at 60Hz. A new special
event has been added, event -1, which returns the high resolution
current time stamp. The event number is specified in the field EVNT of a
Added a simplified GPS interface (direct time interface).
Corrected a bug concerning the vxWorks time clock. I set the clock to
the wrong time stamp, which meant that the vxWorks ansiTime library
function would not work. I also set the TIMEZONE vxworks environment
variable from the EPICS variable EPICS_TS_MIN_WEST variable.
Added an environment variable that points to an NTP server.
dbLoadTemplate and dbLoadRecords
Changed dbLoadTemplate and dbLoadRecords to accept the tilda (~).
cpp Step Added to snc Rule
A cpp preprocessing step has been added to the state notation
language build rule in RULES.Vx.
Target Specific Flags and Load Libraries Now Supported
Target specific flags and target specific load libraries in the EPICS
Makefiles are now supported by specifying definitions for <name>_CFLAGS,
<name>_CCFLAGS, <name>_LDFLAGS and/or <name>_LDLIBS in the Makefiles, where
<name> is the basename of the makefile target. For example, to specify the
compiler option -fshared-data for the target drvAt5Vxi.o the line
"drvAt5Vxi_CFLAGS = -fshared-data" should be placed in the Makefile.Vx file.
RANLIB Only Used If Defined
A test for the definition of RANLIB has been added to the RULES.Unix file so
RANLIB only needs to be defined if it will be used in building libraries.
cpp Definition Fixed in CONFIG.Vx.68k
The definition of CPP has been changed to "$(VX_GNU_BIN)/cpp68k -nostdinc".
Multiple Architecture Builds
The definitions of CROSS_COMPILER_HOST_ARCHS and CROSS_COMPILER_TARGET_ARCHS
were added to the CONFIG_SITE file to allow a site to optionally specify only
a subset of their host architectures to do cross compiling.
New epics/startup Directory
A new startup directory has been created within the epics tree containing files
which set HOST_ARCH and the epics user's path.
HOST_ARCH Definition Changed
HOST_ARCH now obtained by execution of the /usr/local/epics/startup/HostArch
script in CONFIG_SITE and makesdr.
Solaris Native Build Now Default
Config file changes mad to make solaris native build default
Config files and base/tools/sgiinstall file added to support EPICS sgi build
CONFIG_ENV was split to create the new file CONFIG_SITE_ENV
Clean Rule Modified
The clean rule in RULES.Unix and RULES.Vx now removes all *.c, *.i,
and *.st files in the O. directories.
Vx Library Build Rule Now Used By base Directories
The Makefiles.Vx files in many of the base/src directories
have been changed to use the library build rule in RULES.Vx.
Top Level Rules clean & uninstall Modified
Top level base Makefile was modified so that the rules clean and
uninstall affect only the current BUILD_ARCHS directories.
Builds Of base And extensions No Longer Have Path Requirements
Modifications were make to GetVar, getrel, blderrSymTbl, bldEnvData,
and makesdr to remove the $DVL/base/tools and $DVL/base/bin/$(T_A)
build path requirements. When $DVL/base/tools is removed from developer's
path, he/she should invoke gnumake (not gmake). New EPICS parameter added
to bldEnvData and blderrSymTbl
epics/base Files Moved And Removed
Moved from the libCom directory to the db directory to allow libCom
to build without first building the ascii directory (record headers).
bldEnvData blderrSymTbl makeStatTbl
Moved from base/tools to base/src/libCom directory since they are
only used for builds of libCom.
Moved from base/tools to base directory because it is only used by
base toplevel Makefiles
removed files CheckArch,Clean,MakeDirs
Added the script functionality to base/Makefile
EPICS now passed as a param to scripts that need it
base toplevel Makefile changed so that MakeDirs no longer necessary
Fixed cmments at end of #endif statements.
ACC_STRICT Definitions Added For hp700
Added definitions for ACC_STRICT_INVOKE_W_NO, ACC_STRICT_INVOKE_W_YES,
HPACC_STRICT_INVOKE_W_NO, and HPACC_STRICT_INVOKE_W_YES.
Motif directories definitions changed for sun5.4 SDK
MOTIF_INC from /opt/SUNWmotif/include to /usr/dt/include
MOTIF_LIB from /opt/SUNWmotif/lib to /usr/dt/lib
