Install Windows SDK 7.0 - version 7.1 doesn't work with cuda toolkit 3.2 and doesn't contain OpenMP.

Create directory C:\Program Files\Microsoft Visual Studio 9.0\Common7\Tools
Copy vcvars32.bat there, from C:\Program Files\Microsoft Visual Studio 9.0\VC\bin.
Rename vcvars32.bat to vsvars32.bat; only if does not already exist.
CUDA Toolkit requires that file.

Run "Windows SDK 7.0 Command Prompt" from
Start->All programs->Microsoft Windows SDK->Windows SDK 7.0 Command Prompt

Run SetEnv for platform
example SetEnv /xp

Go to bd_box\src directory.

Run nmake -f bd_box.mak
example: nmake -f bd_box.mak nodebug=1 openmp=1 CPU=AMD64
example: nmake -f bd_box_gpu.mak nodebug=1 openmp=1 CPU=AMD64

or use VS and bd_box.sln and bd_box_gpu.sln.
