# 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.# WARNING: know what you are doing before using this. If# you test multiple copies of Crafty (each copy using just# one thread) you can have bogus results because if compiled# with -DAFFINITY, even a single-cpu execution will lock led# itself onto processor zero (since it only has thread #0)# which is probably NOT what you want. This is intended to# be used when you run Crafty using a complete dedicated# machine with nothing else running at the same time.# -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.# -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.# -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.# -DSYZYGY This enables syzygy endgame tables (both WDL and DTC)# -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.## Note: If you compile on a machine with the hardware popcnt# instruction, you should use the -mpopcnt compiler option# to make the built-in intrinsic use the hardware rather than# the "folding" approach. That is the default in this# Makefile so if you do NOT have hardware popcnt, remove all# of the -mpopcnt strings in the Makefile lines below.#default:$(MAKE) -j unix-clanghelp:@echo "You must specify the system which you want to compile for:"@echo ""@echo "make unix-clang Unix w/clang compiler (MacOS usually)"@echo "make unix-gcc Unix w/gcc compiler"@echo "make unix-icc Unix w/icc compiler"@echo "make profile profile-guided-optimizations"@echo " (edit Makefile to make the profile"@echo " option use the right compiler)"@echo ""quick:$(MAKE) target=UNIX \CC=clang \opt='-DSYZYGY -DTEST -DTRACE -DCPUS=4' \CFLAGS='-mpopcnt -Wall -Wno-array-bounds -pipe -O3' \LDFLAGS='$(LDFLAGS) -lstdc++' \crafty-makeunix-gcc:$(MAKE) -j target=UNIX \CC=gcc \opt='-DSYZYGY -DTEST -DCPUS=4' \CFLAGS='-Wall -Wno-array-bounds -pipe -O3 -fprofile-use \-mpopcnt -fprofile-correction -pthread' \LDFLAGS='$(LDFLAGS) -fprofile-use -pthread -lstdc++' \crafty-makeunix-gcc-profile:$(MAKE) -j target=UNIX \CC=gcc \opt='-DSYZYGY -DTEST -DCPUS=4' \CFLAGS='-Wall -Wno-array-bounds -pipe -O3 -fprofile-arcs \-mpopcnt -pthread' \LDFLAGS='$(LDFLAGS) -fprofile-arcs -pthread -lstdc++ ' \crafty-makeunix-clang:@/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/llvm-profdata merge -output=crafty.profdata *.profraw$(MAKE) -j target=UNIX \CC=clang \opt='-DSYZYGY -DTEST -DCPUS=4' \CFLAGS='-Wall -Wno-array-bounds -pipe -O3 \-mpopcnt -fprofile-instr-use=crafty.profdata' \LDFLAGS='$(LDFLAGS) -fprofile-use -lstdc++' \crafty-makeunix-clang-profile:$(MAKE) -j target=UNIX \CC=clang \opt='-DSYZYGY -DTEST -DCPUS=4' \CFLAGS='-Wall -Wno-array-bounds -pipe -O3 \-mpopcnt -fprofile-instr-generate' \LDFLAGS='$(LDFLAGS) -fprofile-instr-generate -lstdc++ ' \crafty-makeunix-icc:$(MAKE) -j target=UNIX \CC=icc \opt='-DSYZYGY -DTEST -DCPUS=4' \CFLAGS='-Wall -w -O2 -prof_use -prof_dir ./prof -fno-alias \-mpopcnt -pthread' \LDFLAGS='$(LDFLAGS) -pthread -lstdc++' \crafty-makeunix-icc-profile:$(MAKE) -j target=UNIX \CC=icc \opt='-DSYZYGY -DTEST -DCPUS=4' \CFLAGS='-Wall -w -O2 -prof_gen -prof_dir ./prof -fno-alias \-mpopcnt -pthread' \LDFLAGS='$(LDFLAGS) -pthread -lstdc++ ' \crafty-makeprofile:@rm -rf *.o@rm -rf log.*@rm -rf game.*@rm -rf prof@rm -rf *.gcda@mkdir prof@touch *.c *.h$(MAKE) -j unix-clang-profile@echo "#!/bin/csh" > runprof@echo "./crafty <<EOF" >>runprof@echo "bench" >>runprof@echo "mt=0" >>runprof@echo "quit" >>runprof@echo "EOF" >>runprof@chmod +x runprof@./runprof@rm runprof@touch *.c *.h$(MAKE) -j unix-clang## one of the two following definitions for "objects" should be used.
