# setup and configuration #
###########################

# Note: this Makefile may need modified depending upon which type of machine
# you are to compile the driver.  In particular, if you are using an HP,
# Sequent, or RS/6000, be sure to search the Makefile for all comments
# pertaining to your machine.

# note: Edit options.h to further configure the driver for your particular mud.
# Also, be sure to look at the EXTRALIBS macro later in the Makefile.
# Some machines require it to be set to a specific value.

# Set INSTALL_DIR to the directory where you want to install the executables.
INSTALL_DIR = ../bin

# Change this if you wish the driver binary to be named something other than
# driver.
DRIVER_BIN = driver

# uncomment RESOLV if your machine has libresolv.a in /lib or /usr/lib
#RESOLV=-lresolv

# uncomment one MALLOC if you wish to use BSD malloc or Smalloc.
# Both of these require the sbrk() system call.  Be sure to read the
# comments in the bsdmalloc.c file before deciding on BSDMALLOC.
# note: These mallocs may not work correctly on the NeXT or other systems
# that don't fully support sbrk().  It is okay not to use either of these
# two mallocs in which case you will get system malloc (read the comments
# in options.h for choices on malloc statistics and debugging).
#
# uncomment this line for BSD Malloc.
#MALLOC=bsdmalloc.c
# uncomment this line for Smalloc
#MALLOC=smalloc.c

# uncomment STR if your machine is missing memcpy(), memset(), strtol(),
# and strcspn().
#STRFUNCS=strfuncs.c

# uncomment UALARM if your machine is missing ualarm() (e.g. those
# running Linux)
#UALARM=ualarm.c

# RS/6000 AIX: use this OSFLAGS line (required).
#OSFLAGS=-D_BSD

# If you don't have strchr() and strrchr(), uncomment following STR line
#STR=-Dstrchr=index -Dstrrchr=rindex

#Enable warnings from the compiler, if wanted.
#WARN=-Wall

# define profiling if you want it
# note: the gmon.out file will likely be written in the mudlib dir.
# PROFILE_ON controls whether or not monitoring is active at driver
# startup.  Comment PROFILE_ON to make profiling not active at startup.
# Use moncontrol(1) efun to enable profiling and moncontrol(0) to turn
# it off.
#PROFILE_ON=-DPROFILE_ON
# Uncomment this if you want to enable profiling of the driver
#PROFIL=-pg -DPROFILING $(PROFILE_ON)

# define this if you want (compiler) optimization enabled.
# *WARNING* using high levels of optimization (e.g. -O3) can cause some
# compilers to produce incorrect code.  If the driver is behaving
# inexplicably, try using a lower level of optimization (or none).
# Uncomment one or none of the following optimization lines.  The
# first is the safer, the second is the one likely to produce more
# improvement in driver speed (it uses GCC flags).
#
#OPTIMIZE=-O
OPTIMIZE=-O2 -fomit-frame-pointer -fstrength-reduce

# MIRE stuff
# you can ignore this, it's for erik's custom use
#MIRE=-DMIRE
#MIRE_C=mire.c
#MIRELIBS=-ltext libDtype.a libeditor.a libdoppelganger.a -ldsys -lndcommon -lndclient -lorwant

# uncomment DEBUG to enable run time debugging.
#DEBUG=-g -DDEBUG
# uncomment DEBUG_MACRO to compile in debug() macro code
#DEBUG_MACRO=-DDEBUG_MACRO
# prevent -DDEBUG from abort()'ing the driver (when in -DDEBUG mode)
#DEBUG_NON_FATAL=-DDEBUG_NON_FATAL

# if you use gcc (including NeXT cc) and have lots of RAM, try uncommenting
#  this for speedier compiles:
#PIPE=-pipe


# try uncommenting this if you are using gcc and at runtime you see socket
# errors saying that the "set socket nonblocking" operation is not supported.
# That error is caused by old-style macros (that gcc doesn't normally grok)
# used by ioctl on some systems.
#NEED_OLD_CPP=-traditional-cpp

# set CC=cc on a NeXT (or gcc if you have a newer version than the NeXT
# comes with) and to gcc on other machines (if possible)
#
# NOTE: If you are using gcc (especially on a sun4), and the driver gives
# a runtime error regarding "operation not supported on socket", then
# try using cc instead (some installations of gcc have an error in one of
# the system include (.h) files that prevents the socket operation from
# working correctly).

# RS/6000 AIX: use this EXTRALIBS line (required).

#EXTRALIBS=-lBSD

# NeXT: link with MallocDebug if you have a NeXT with NeXTOS 2.1 or later and
# you wish to search for memory leaks (see /NextDeveloper/Apps/MallocDebug).
# Note: linking with MallocDebug will cause the virtual size of the
# driver process to reach appoximately 40MB however the amount of real memory
# used will remain close to normal.
#EXTRALIBS=-lMallocDebug -lsys_s

# Sequent DYNIX/ptx: use this EXTRALIBS line (required).
