#
# This GNU make makefile has been tested on:
#   Linux (x86 & Sparc & PPC)
#   OS X
#   Solaris (x86 & Sparc) (gcc and Sun C)
#   OpenBSD
#   NetBSD
#   FreeBSD
#   HP-UX
#   AIX
#   Windows (MinGW & cygwin)
#   Linux x86 targeting Android (using agcc script)
#   Haiku x86 (with gcc4)
#
# Android targeted builds should invoke GNU make with GCC=agcc on
# the command line.
#
# In general, the logic below will detect and build with the available
# features which the host build environment provides.
#
# Dynamic loading of libpcap is the preferred default behavior if pcap.h 
# is available at build time.  Support to statically linking against libpcap
# is deprecated and may be removed in the future.  Static linking against 
# libpcap can be enabled if GNU make is invoked with USE_NETWORK=1 on the 
# command line.
#
# Some platforms may not have vendor supplied libpcap available.  HP-UX is 
# one such example.  The packages which are available for this platform
# install include files and libraries in user specified directories.  In 
# order for this makefile to locate where these components may have been 
# installed, gmake should be invoked with LPATH=/usr/lib:/usr/local/lib 
# defined (adjusted as needed depending on where they may be installed).
#
# The default build will build compiler optimized binaries.
# If debugging is desired, then GNU make can be invoked with
# DEBUG=1 on the command line.
#
# simh project support is provided for simulators that are built with 
# dependent packages provided with the or by the operating system 
# distribution OR for platforms where that isn't directly available (OS X) 
# by packages from specific package management systems (MacPorts).  Users 
# wanting to build simulators with locally build dependent packages or 
# packages provided by an unsupported package management system can 
# override where this procedure looks for include files and/or libraries.  
# Overrides can be specified by define exported environment variables or 
# GNU make command line arguments which specify INCLUDES and/or LIBRARIES.  
# Each of these, if specified, must be the complete list include directories
# or library directories that should be used with each element separated by 
# colons. (i.e. INCLUDES=/usr/include/:/usr/local/include/:...)
#
# Some environments may have the LLVM (clang) compiler installed as
# an alternate to gcc.  If you want to build with the clang compiler, 
# invoke make with GCC=clang.
#
# Internal ROM support can be disabled if GNU make is invoked with
# DONT_USE_ROMS=1 on the command line.
#
# The use of pthreads for various things can be disabled if GNU make is 
# invoked with NOPTHREADS=1 on the command line.
#
# Asynchronous I/O support can be disabled if GNU make is invoked with
# NOASYNCH=1 on the command line.
#
# For linting (or other code analyzers) make may be invoked similar to:
#
#   make GCC=cppcheck CC_OUTSPEC= LDFLAGS= CFLAGS_G="--enable=all --template=gcc" CC_STD=--std=c99
#
# CC Command (and platform available options).  (Poor man's autoconf)
