# To build crafty:## You want to set up for maximum optimization, but typically you will# need to experiment to see which options provide the fastest code. The# following option descriptions explain each option. To use one or more# of these options, to the "opt =" line that follows the explanations and# add the options you want, being careful to stay inside the single quote# marks.## -DAFFINITY Include code to set processor/thread affinity on Unix# systems. Note this will not work on Apple OS X as it does# not support any sort of processor affinity mechanism.# -DBOOKDIR Path to the directory containing the book binary files.# The default for all such path values is "." if you don't# specify a path with this macro definition.# -DCPUS=n Defines the maximum number of CPUS Crafty will be able# to use in a SMP system. Note that this is the max you# will be able to use. You need to use the smpmt=n command# to make crafty use more than the default 1 process.# -DDEBUG This is used for testing changes. Enabling this option# greatly slows Crafty down, but every time a move is made,# the corresponding position is checked to make sure all of# the bitboards are set correctly.# -DEPD If you want full EPD support built in.# -DINLINEASM Compiles with the Intel assembly code for FirstOne(),# LastOne() and PopCnt(). This is for gcc-style inlining# and now works with the Intel C/C++ compiler as well. It# also has a MSVC compatible version included.# -DLOGDIR Path to the directory where Crafty puts the log.nnn and# game.nnn files.# -DNODES This enables the sn=x command. Crafty will search until# exactly X nodes have been searched, then the search# terminates as if time ran out.# -DNOEGTB Eliminates the egtb code for compilers that can't deal# with the large egtb.cpp code/templates.# -DNUMA Says this system is NUMA, which is mainly used for Linux# or Windows systems, and references libnuma, needed for the# NUMA calls (crafty doesn't use many of these, it does the# memory setup stuff itself)# -DPOPCNT Says this system is a newer Intel/AMD processor with the# built-in hardware popcnt instruction.# -DPOSITIONS Causes Crafty to emit FEN strings, one per book line, as# it creates a book. I use this to create positions to use# for cluster testing.# -DRCDIR Path to the directory where we look for the .craftyrc or# crafty.rc (windows) file.# -DSKILL Enables the "skill" command which allows you to arbitrarily# lower Crafty's playing skill so it does not seem so# invincible to non-GM-level players.# -DTBDIR Path to the directory where the endgame tablebase files# are found. default = "./TB"# -DTEST Displays evaluation table after each move (in the logfile)# -DTRACE This enables the "trace" command so that the search tree# can be dumped while running.# -DUNIX This identifies the target O/S as being Unix-based, if this# option is omitted, windows is assumed.default:$(MAKE) -j unix-gcchelp:@echo "You must specify the system which you want to compile for:"@echo ""@echo "make
