# 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.
#   
#   -DBOOKDIR      N  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       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.
#   -DEPD          Y  if you want full EPD support built in.
#   -DINLINE32     N  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.
#   -DINLINE64     N  Compiles with the Intel assembly code for FirstOne(),
#                     LastOne() and PopCnt() for the AMD opteron, only tested
#                     with the 64-bit opteron GCC compiler / Intel ICC compiler.
#   -DLIMITEXT     N  limit extensions as search gets deeper
#   -DLOGDIR       N  path to the directory where Crafty puts the log.nnn and
#                     game.nnn files.
#   -DNOEGTB       N  eliminates the egtb code for compilers that can't deal
#                     with the large egtb.cpp code/templates.
#   -DNOFUTILITY   N  disables classic futility pruning
#   -DNUMA         N  says this system is NUMA, which is mainly used for Linux
#                     systems, and references libnuma, needed for the NUMA calls
#                     (crafty doesn't use many of these, it does the memory
#                     setup stuff itself)
#   -DPOPCNT       N  Compiles with the Intel assembly code for hardware popcnt
#                     instruction, only applies to Nehalem and beyond (I think
#                     this is SSE 4.2 or something similar).
#   -DPOWERPC      N  enables PPC spinlock inline function for SMP boxes only
#   -DRCDIR        N  path to the directory where we look for the .craftyrc or
#                     crafty.rc (windows) file.
#   -DTBDIR        N  path to the directory where the endgame tablebase files
#                     are found.  default = "./TB"
#   -DTRACE        N  This enables the "trace" command so that the search tree
#                     can be dumped while running.
