# The following is for easier adaptation on your machine. See also README.Amiga .
# It is a derivate of the original 'Makefile' adapted for SAS' own smake.
#
# I (Reinhard) used SAS/C 6.50 to compile the driver with the smake utility
# and a port of BYacc.
# SAS/C supports a generic startup with common macro definitions, so for me
# the following macros are defined automatically:
#

CC = sc:c/sc
LD = sc:c/sc link
AS = sc:c/sc asm
CFLAGS=
SCFLAGS=

YTAB= y.tab
CP= c:copy
RM= c:delete
MV= c:rename

#
# The original makefile had 'CC= gcc' in it...
# The CFLAGS- and YFLAGS-values are modified for Mud-Stuff below.
# There is also a section below where you can add your own pet compiler.
#-----------------------------------------------------------------------------

# What type of net package do we use? Known by this Makefile are:
#   AS225 : Commodores AS225 software
#   AMITCP: The AmiTCP package from hut.fi
#
# Leave it empty for the simulation (the default).

NETTYPE= AMITCP

# DMake's default-yacc 'Bison' won't work with Amylaars lang.y,
# but byacc will.

# Unix has an option '-f' for it's 'rm' - not the Amiga, so I define
#   RMF= $(RM) -f
# and modify it for Amiga as:

# -- Compiler specifics --
#
# Set CCOPTS to any options you need to compile LPMud, what includes
# warning- and optimization options!
#
# If your compiler doesn't define the cpp-symbol AMIGA, it's a good idea
# to add it here.
# If your compiler doesn't have own code for float maths, you must
# define _NO_OWN_FLOATS so OS 1.3-versions will compile properly.
#
# interpret.c and lang.c need lots of RAM to compile, thus it might be wise
# to put the temporaries somewhere else than into T: in RAM:.
# Use these macros to insert the needed compiler-options, including any
# non-standard code-model options.
#   LOPT: The options for lang.c
#   IOPT: The options for interpret.c
#
# To compile the hosts/amiga/signal, your compiler must be able to
# generate C-Code with registerized parameters. If it needs a special
# option to do this, put it into ROPT.
#
# If your compiler needs additional sources, put them into XSRC, and
# the object files to generate into XOBJ.
# If your compiler doesn't have alloca(), add alloca.c/alloca.o to
# the additional sources.

# afp tells SAS/C to generate 32-bit references to functions
# Data=FAR tells SAS/C to use 32-bit references (no force)
# Code=FAR tells SAS/C to use 32-bit references to functions not declared in current file
# lib=scmffpnb.lib tells SAS/C to generate code to call the FFP shared library
# SAS/C uses the OS' math libraries
# AMIGA is defined automatically
