#### CONFIGURATION

# Uncomment one of the 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


# Do you compile on Windows instead of Linux? Please note that the
# performance may not be optimal.
# (XXX: For now, only the mingw target is supported on Windows.
# Patches for others are welcome!)

# WIN=1

# To compile 64-bit version in msys2 with mingw64, uncomment the
# following line
# MSYS2_64=1

# Do you compile on MacOS/X instead of Linux? Please note that the
# performance may not be optimal.
# (XXX: We are looking for volunteers contributing support for other
# targets, like mingw/Windows.)

# MAC=1

# 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

# 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 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


# Target directories when running `make install`. Note that this is NOT
# quite supported yet - Pachi will work fine, but will always look for
# extra data files (such as pattern, joseki or fuseki database) only
# in the current directory, bundled database files will not be installed
# in a system directory or loaded from there.
PREFIX=/usr/local
BINDIR=$(PREFIX)/bin

# 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.)
