Makefile

############################ CONFIGURATION ############################

# Tweak options below to change the way Pachi is built.
# Alternatively, you can pass the option to make itself, like:
# 	make MAC=1 DOUBLE_FLOATING=1
# or use the short aliases (make fast, make generic ...)

################################ Build ################################

# Generic build ?
# If binary will be distributed you need this !
# Otherwise you may do without to enable more aggressive optimizations
# for this machine only.

# GENERIC=1

# Do you compile on Windows instead of Linux ?
# Please note that performance may not be optimal.
# To compile in msys2 with mingw-w64, uncomment the following line.
# See Makefile.msys2 for further configuration.

# MSYS2=1

# Do you compile on MacOS/X instead of Linux?
# Please note that performance may not be optimal.

# MAC=1

############################ Deep Learning ############################

# Compile Pachi with dcnn support ?
# You'll need to install Boost and Caffe libraries.
# If Caffe is in a custom directory you can set it here.

DCNN=1
# CAFFE_PREFIX=/usr/local/caffe

# Supported networks:
# Comment out those you don't need for speed.

DCNN_DETLEF=1
DCNN_DARKFOREST=1

############################ Special Builds ###########################

# Fixed board size. Set this to enable more aggressive optimizations
# if you only play on 19x19. Pachi won't be able to play on other
# board sizes.

# BOARD_SIZE=19

# Build josekifix module ?
# Provides fixes for joseki lines that dcnn plays poorly, and more varied
# fusekis when playing as black.

JOSEKIFIX=1

# Running multiple Pachi instances ? Enable this to coordinate them so that
# only one takes the cpu at a time. If your system uses systemd beware !
# Go and read note at top of fifo.c

# FIFO=1

# By default, Pachi uses low-precision numbers within the game tree to
# conserve memory. This can become an issue with playout counts >1M,
# e.g. with extremely long thinking times or massive parallelization;
# 24 bits of floating_t mantissa become insufficient then.

# DOUBLE_FLOATING=1

# Enable distributed engine for cluster play ?

# DISTRIBUTED=1
# NETWORK=1

# Compile Pachi with external plugin support ?
# If unsure leave disabled, you most likely don't need it.

# PLUGINS=1

# Build extra engines used for development ?
# EXTRA_ENGINES=1

# Compile extra tests ? Enable this to test board implementation.
# BOARD_TESTS=1

############################## Profiling ##############################

# Enable performance profiling using gprof. Note that this also disables
# inlining, which allows more fine-grained profile, but may also distort
# it somewhat.

# PROFILING=gprof

# Enable performance profiling using google-perftools. This is much
# more accurate, fine-grained and nicer than gprof and does not change
# the way the actual binary is compiled and runs.

# PROFILING=perftools

############################### Install ###############################

# Target directories when running 'make install'.
# Pachi will look for its data files (dcnn, pattern, joseki etc) in
# system directory below (in addition to current directory / DATA_DIR
# environment variable if present).
PREFIX=$(DESTDIR)/usr
BINDIR=$(PREFIX)/bin
DATADIR=$(PREFIX)/share/pachi-go

# Generic compiler options. You probably do not really want to twiddle
# any of this.
# (N.B. -ffast-math breaks us; -fomit-frame-pointer is added below
# unless PROFILING=gprof.)
