Peter do this:
use this makefile, named "makefile.nt"
# Base compiler flags needed for build:
BFLAGS = /D_CONSOLE /DWIN32
# Compiler flags:
# /O2 optimize for speed
# /Oa assume no aliasing (no good for VC 6 without SP3)
# /Gr fastcall calling convention
# /G5 target Pentium (but will run on all x86 architectures)
# /G6 target Pentium Pro (but will run on all x86 architectures)
# /Ob2 inline function calls if suitable
#
# For debugging use these flags instead:
# CFLAGS = /Od /Zi
# LDFLAGS = /DEBUG /DEBUGTYPE:CV
#
CFLAGS = /GL /O2 /Ox /Ot /Gr /Ob2 /w
#/GL
#CFLAGS = /Od /Zi
#CFLAGS = /Ox /G6 /Gr /Ob2
# Linker flags, normally not needed except for debug builds:
#LDFLAGS =
LDFLAGS =/ltcg:pgi /pgd:wcrafty.pgd
#LDFLAGS = /ltcg:pgo /pgd:wcrafty.pgd
#Nmake /A -f makefile.nt
#Nmake -f makefile.nt
#LDFLAGS = /DEBUG /DEBUGTYPE:CV
# See the default crafty makefile for a description of the options below.
# With VC++, defines like COMPACT_ATTACKS, etc, makes the code slower, so
# those # options are disabled by default. FAST is normally not defined
# so that hash statistics are reported -- for the fastest possible
# executable, define FAST below. for 6 piece EGTB support, add /DEGTB6.
#COPTS = /DFAST
# For an SMP build use/add the following build options.
# NT_INTEREX is defined if you want to use the built-in InterlockedExchange()
# function for thread resource locking, instead of the inline asm routine.
# (This shouldn't be needed, at least on Intel.)
# /MT is a compiler flag needed for multithreaded builds.
#COPTS = /MT /DSMP /DCPUS=4 /DNT_INTEREX /DNUMA /DFUTILITY
COPTS = /MT /DSMP /DCPUS=2 /DFAST /D_M_AMD64 /DFUTILITY
# If you are using any external assembler routines, put the name of the
# object code file(s) here. Any such files will need to be generated
# separately -- there is no assembler step defined in the makefile.
asmobjs =
# To enable assembly optimizations in vcinline.h, use
/DVC_INLINE_ASM.DINLINE_AMD

===============================================
select your command compiler
->START>PROGRAMS>MICROSOFT VISUAL STUDIO 5 BETA>VISUAL STUDIO TOOLS><select
command compiler>
navigate through the "dos" window to where your crafty sources are and copy
paste this into the window:
Nmake craftyx /A -f makefile.nt
start the wcrafty.exe and type bench - let it run ...
quit wcraftyx
type/copy this at the command prompt
"link =/ltcg:pgi /pgd:wcrafty.pgd"
Best,
Mike
