<BLOCKQUOTE>The Experimental Physics and Industrial Control Systems
|
|
(EPICS) is an extensible set of software components and tools with
|
|
which application developers can create a control system. This control
|
|
system can be used to control accelerators, detectors, telescopes, or
|
|
other scientific experimental equipment. EPICS base is the set of core
|
|
software, i.e. the components of EPICS without which EPICS would not
|
|
function. EPICS base allows an arbitrary number of target systems, IOCs
|
|
(input/output controllers), and host systems, OPIs (operator
|
|
interfaces) of various types.</BLOCKQUOTE>

|
|
|
|
<BLOCKQUOTE>The list of platforms supported by this version of EPICS base
|
|
is given in the configure/CONFIG_SITE file. If you are trying to build
|
|
EPICS Base on an unlisted host or for a different target machine you
|
|
must have the proper host/target cross compiler and header files, and
|
|
you will have to create and add the appropriate new configure files to
|
|
the base/configure/os/directory. You can start by copying existing
|
|
configuration files in the configure/os directory and then make changes
|
|
for your new platforms.</BLOCKQUOTE>
|
|
|
|
<H3><A NAME="0_0_5"> Supported compilers</A></H3>
|
|
|
|
<BLOCKQUOTE>This version of EPICS base has been built and tested using the host
|
|
vendor's C and C++ compilers, as well as the GNU gcc and g++ compilers. The GNU
|
|
cross-compilers work for all cross-compiled targets. You may need the C and C++
|
|
compilers to be in your search path to do EPICS builds; check the definitions
|
|
of CC and CCC in base/configure/os/CONFIG.<host>.<host> if you have
|
|
problems.</BLOCKQUOTE>

|
|
<H3><A NAME="0_0_6"> Software requirements</A></H3>
|
|
|
|
<BLOCKQUOTE><B>GNU make</B><BR>
|
|
You must use GNU make, gnumake, for any EPICS builds. Set your path
|
|
so that a gnumake version 3.81 or later is available.
|
|
|
|
<P><B>Perl</B><BR>
|
|
You must have Perl version 5.8.1 or later installed. The EPICS configuration
|
|
files do not specify the perl full pathname, so the perl executable must
|
|
be found through your normal search path.</P>
|
|
|
|
<P><B>Unzip and tar (Winzip on WIN32 systems)</B><BR>
|
|
You must have tools available to unzip and untar the EPICS base
|
|
distribution file.</P>
|
|
|
|
<P><B>Target systems</B><BR>
|
|
EPICS supports IOCs running on embedded platforms such as VxWorks
|
|
and RTEMS built using a cross-compiler, and also supports soft IOCs running
|
|
as processes on the host platform.</P>
|
|
|
|
<P><B>vxWorks</B><BR>
|
|
You must have vxWorks installed if any of your target systems are
|
|
vxWorks systems. This provides the cross-compiler and header files
|
|
needed to build for these target systems. The absolute path to and version
|
|
number of the vxWorks installation is normally specified in the
|
|
base/configure/os/CONFIG_SITE.Common.vxWorksCommon file. Consult the EPICS web
|
|
pages about <a href="http://www.aps.anl.gov/epics/base/tornado.php">vxWorks
|
|
5.x</a> and <a href="http://www.aps.anl.gov/epics/base/vxWorks6.php">vxWorks
|
|
6.x</a> and the vxWorks documentation for information about configuring your
|
|
vxWorks operating system for use with EPICS.</P>
|
|
|
|
<P><B>RTEMS</B><BR>
|
|
For RTEMS targets, you need RTEMS core and toolset version 4.9.2 or later.</P>
|
|
|
|
<P><B>GNU readline or Tecla library</B><BR>
|
|
GNU readline and Tecla libraries can be used by the IOC shell to
|
|
provide command line editing and command line history recall and edit.
|
|
GNU readline (or Tecla library) must be installed on your target system
|
|
when COMMANDLINE_LIBRARY is set to READLINE (or TECLA) for that target.
|
|
EPICS (EPICS shell) is the default specified in CONFIG_COMMON. A
|
|
READLINE override is defined for linux-x86 in the EPICS distribution.
|
|
Comment out COMMANDLINE_LIBRARY=READLINE in
|
|
configure/os/CONFIG_SITE.Common.linux-x86 if readline is not installed
|
|
on linux-x86. Command-line editing and history will then be those
|
|
supplied by the os. On vxWorks the ledLib command-line input library is
|
|
used instead.</P>

<P><B>EPICS_HOST_ARCH</B><BR>
|
|
Before you can build or use EPICS R3.14, the environment variable
|
|
EPICS_HOST_ARCH must be defined. A perl script EpicsHostArch.pl in the
|
|
base/startup directory has been provided to help set EPICS_HOST_ARCH.
|
|
You should have EPICS_HOST_ARCH set to your host operating system
|
|
followed by a dash and then your host architecture, e.g. solaris-sparc.
|
|
If you are not using the OS vendor's c/c++ compiler for host builds,
|
|
you will need another dash followed by the alternate compiler name
|
|
(e.g. "-gnu" for GNU c/c++ compilers on a solaris host or "-borland"
|
|
for Borland c/c++ compilers on a WIN32 host). See configure/CONFIG_SITE
|
|
for a list of supported EPICS_HOST_ARCH values.</P>

<P><B>PERLLIB</B><BR>

On WIN32, some versions of Perl require that the environment
|
|
variable PERLLIB be set to <perl directory location>.</P>
|
|
|
|
<P><B>PATH</B><BR>
|
|
As already mentioned, you must have the perl executable and you may
|
|
need C and C++ compilers in your search path. For building base you
|
|
also must have echo in your search path. For Unix host builds you also
|
|
need ln, cpp, cp, rm, mv, and mkdir in your search path and /bin/chmod
|
|
must exist. On some Unix systems you may also need ar and ranlib in
|
|
your path, and the C compiler may require as and ld in your path. On
|
|
solaris systems you need uname in your path.</P>
|
|
|
|
<P><B>LD_LIBRARY_PATH</B><BR>
|
|
It is no longer necessary to have LD_LIBRARY_PATH include EPICS
|
|
directories on a Unix type system. R3.14 shared libraries and
|
|
executables will contain the full path name to libraries they require.
|
|
However, if you move the EPICS directories from their build-time
|
|
location then in order for libraries to be found at runtime
|
|
LD_LIBRARY_PATH must include the full pathname to
|
|
$(INSTALL_LOCATION)/lib/$(EPICS_HOST_ARCH) when invoking executables.
|
|
Building shared libraries is now the default setting for all Unix type
|
|
hosts. NOTE: You will still need LD_LIBRARY_PATH for R3.13 extension
|
|
shared libraries even if the R3.13 extensions are built with R3.14
|
|
base.</P>
|
|
|
|
<P><B>Win32 PATH</B><BR>
|
|
On WIN32 systems, for R3.14.7 and later, it is no longer necessary
|
|
to add fullpathname to $(INSTALL_LOCATION)/bin/$(EPICS_HOST_ARCH) to
|
|
your path for finding dlls during EPICS builds. The win32 configure
|
|
files in base now add this directory to the path definition.</P>

Instructions for building and executing the 3.14 example application
|
|
can be found in the section "Example Application" of Chapter 2,
|
|
"Getting Started", in the "IOC Application Developer's Guide" for this
|
|
release. The "Example IOC Application" section briefly explains how to
|
|
create and build an example application in a user created <top>
|
|
directory. It also explains how to run the example application on a
|
|
vxWorks ioc or as a process on the host system.
|
|
By running the example application as a host-based IOC, you will be
|
|
able to quickly implement a complete EPICS system and be able to run channel
|
|
access clients on the host system.

|
A perl script,
|
|
makeBaseExt.pl, is included in the distribution file. This script will
|
|
create a sample extension that can be built and executed. The
|
|
makeBaseApp.pl and makeBaseExt.pl scripts are installed into the
|
|
install location bin/<hostarch> directory during the base build.

<BLOCKQUOTE>You can build using a single EPICS directory structure on
|
|
multiple host systems and for multiple cross target systems. The
|
|
intermediate and binary files generated by the build will be created in
|
|
separate subdirectories and installed into the appropriate separate
|
|
host/target install directories. EPICS executables and perl scripts are
|
|
installed into the <TT>$(INSTALL_LOCATION)/bin/<arch></TT> directories.
|
|
Libraries are installed into $<TT>(INSTALL_LOCATION)/lib/<arch></TT>.
|
|
The default definition for <TT>$(INSTALL_LOCATION)</TT> is <TT>$(TOP)</TT>
|
|
which is the root directory in the distribution directory structure,
|
|
base. Created object files are stored in O.<arch> source
|
|
subdirectories, This allows objects for multiple cross target
|
|
architectures to be maintained at the same time. To build EPICS base
|
|
for a specific host/target combination you must have the proper
|
|
host/target C/C++ cross compiler and target header files and the
|
|
base/configure/os directory must have the appropriate configure files.
