#
# GCC based makefile
#
# 05/24/2012 2.0 wbw - changed to handle HBIOS
#
# 01/11/2011 1.4 wbw - added support for ZSDOS/ZDDOS/ZCPR
#
# 12/22/2011 1.3 wbw - removed all built-in config stuff, operation is now entirely
#                      dependent on variables CONFIG, ROMSIZE, and CPU
#
# 12/02/2011 1.3 wbw - replaced makever functionality with built-in makefile stuff
#
# 11/29/2011 1.3 dwg - uses makever to generate stdincl.inc from the version.hpp file
#
# 11/19/2011 1.3 dwg - added n8vem_vdu to "usage" and "all" rules
#                      enhanced clean to get files in $(OUTDIR)
#                      added custom to "all" rule

#
# The operation of this makefile is entirely dependent on the setting
# of three variables: CONFIG, ROMSIZE, and CPU:
#
# CONFIG determines which configuration to build which means that
# it will determine the config_xxx.asm config settings file to
# include as well as the output file names.  So, for example,
# if CONFIG is "n8vem", the config_n8vem.asm file will be used
# for BIOS configuration settings and the output files will be
# n8vem.rom, n8vem.sys, and n8vem.com.
#
# ROMSIZE specifies the size of the ROM image to be produced and
# currently must be either "1024" for a 1MB ROM or "512" for a
# 512KB ROM.
#
# CPU specifies the instruction set to be used in assembly and
# must be either "80" for Z80 or "180" for Z180.  Currently,
# you should use 180 for N8 ROMs and 80 for everything else.
#
# SYS specifies the system variant to build in.  CPM will
# build traditional CP/M.  ZSYS will build ZSystem which
# currently means ZSDOS 1.2 & ZCPR 1.0
#
# ROMNAME names the output file.  It defaults to
# CONFIG.  The output of the build will be:
# <ROMNAME>.rom, <ROMNAME>.sys, and <ROMNAME>.com.
#
# These variables can be passed into the makefile by the command
# line, hardcoded in this file, or set as environment variables
# in the OS.  To use a command line, use the following format:
#
#   make CONFIG=<config> ROMSIZE=<romsize> CPU=<cpu> SYS=<sys> ROMNAME=<romname>
#
# An example of this is:
#
#   make CONFIG=n8vem ROMSIZE=512 CPU=80 SYS=CPM ROMNAME=n8vem
#
# Alternatively, you can specify the variables by hardcoding them
# in this file.  To do so, uncomment the five lines after these
# comments and change the values as desired.
# If the variables are specified this way, you would then invoke
# the make by simply using "make"
#
# If you want to set them as environment variables, you can
# do this with commands like the following at an OS command
# prompt or in a batch file:
#
#   SET CONFIG=n8vem
#   SET ROMSIZE=512
#   SET CPU=80
#   SET SYS=CPM
#   SET ROMNAME=n8vem
#
# Note: use "make clean" to delete temporary and output files
#
# A good idea is to do a clean with every build and this can be
# accomplished on one command line doing something like this:
#
#   make clean all CONFIG=n8vem ROMSIZE=512 CPU=80 SYS=CPM ROMNAME=n8vem
#
# or, if you are using hard coded variables above:
#
#   make clean all
#
# Uncomment and update values below to hardcode settings:
#
#CONFIG := n8vem
#ROMSIZE := 512
#CPU := 80
#SYS := CPM
#ROMNAME := n8vem
