How to build x64 app on x86 win7 system, using windows sdk

Thanks for your attention.

I'm using x86 windows开发者_StackOverflow社区 sdk 7.1 to build x64 app. here is my build bat file:

cd "%SDK_PATH%"

SETLOCAL ENABLEDELAYEDEXPANSION

call "%SDK_PATH%\Bin\setenv.cmd" /Debug /x64 /xp

nmake /B /NOLOGO clean

nmake /B /NOLOGO

But the build tool is still using x86 environment, here is the cl.exe command line:

cl -c -DCRTAPI1=_cdecl -DCRTAPI2=_cdecl -nologo -GS -D_X86_=1 -DWIN32 -D_WIN32 -W3 -_WINNT -D_WIN32_WINNT=0x0501 -DNTDDI _VERSION=0x05010000 -D_WIN32_IE=0x0600 -DWINVER=0x0501 -D_MT -MTd -Zi -Od -DDEBUG /EHsc DDRVMGR_EXPORTS /TP /DUNICODE /D_UNICODE /W0 /WX /Fo"Debug\" /Fd"Debug\" .\main.c

Any idea why this would be happening? Thanks in adv.

This is probably the makefile messing things up. The _WIN32 and WIN32 defines are OK, they're always supposed to be there.
