3.12 EPICS BASE release notes and build instructions.

3.12 EPICS BASE Notes and Build Instructions.
- By Matthew Needes
----------------------------------------------------------------------------
Notes:
1. Before you can build or really use EPICS, you must set your
path properly:
set path = ( $path EPICS/base/tools EPICS/base/bin/HOST_ARCH )
e.g.:
set path = ( $path /home/epics/base/tools /home/epics/base/bin/sun4 )
2. If you are using GNU make (which is now THE supported make utility
for the build), you probably want to invoke it with the
--no-print-directory option when you are building at the TOP level:
make --no-print-directory
This is to turn off the annoying messages GNU make produces upon
entering a directory.

CONFIG - This file is meant to be included in the low-level EPICS Makefiles.
It includes the other EPICS makefiles, and allows individual developers
and the EPICS system manager to override specific variables in the rest of
the configuration.
----------------------------------------------------------------------------
CONFIG_SITE - This file is meant to be changed only by the EPICS system
manager. It specifies:
HOST_ARCH: The system's host architecture (sun4/hp700/etc).
BUILD_ARCHS: List of architectures to be built.
VX_DIR: Location of vxWorks.
STATIC_BUILD: Whether or not to build clients statically.
etc.
----------------------------------------------------------------------------
CONFIG_ARCH.ARCH - This file defines a particular architecture. It
contains the following variables:
BUILD_TYPE: Unix / Vx
ARCH_CLASS: 68k / sun4 / hp700 / etc.
Architecture dependent build flags. The flag names / contents
depend on your architecture class.
----------------------------------------------------------------------------
CONFIG.BUILD_TYPE.ARCH_CLASS - Contains definitions pertaining to a
particular architecture class. This file's primary usefulness is to
define compile and link flags.
----------------------------------------------------------------------------
CONFIG_COMMON - Contains definitions
----------------------------------------------------------------------------
HRULES - Rules for traversing hierarchical directories.
----------------------------------------------------------------------------
RULES.Vx - Rules for building with VxWorks makefiles.
