(2) Download  & uncompress OpenNI2 source. (branch:develop 2.1.0.4)
(26 Jan, 2013 : Both the 'master' and 'develop' were up-to-date.
It's necessary to confirm the version of  branches.) 
Please download a source zip file form Here.
  Download > OpenNI 2.0 source code is available on GitHub > branch develop
Assuming an installation directory "~/OpenNI2-develop".

(3) Set  compiler options for the ARM1176JZF-S
ARM compiler option web-site. HERE 

[root@rcmp-r03 ~]# cd OpenNI2-develop/ThirdParty/PSCommon/BuildSystem
[root@rcmp-r03 BuildSystem]# vi Platform.Arm
[root@rcmp-r03 BuildSystem]# cat Platform.Arm

ifeq "$(CFG)" "Release"
    # Hardware specifying flags
    #CFLAGS += -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp #-mcpu=cortex-a8
  CFLAGS += -mtune=arm1176jzf-s -mfloat-abi=hard
    # Optimization level, minus currently buggy optimizing methods (which break bit-exact)
    #CFLAGS += -O3 -fno-tree-pre -fno-strict-aliasing
    # More optimization flags
   # CFLAGS += -ftree-vectorize -ffast-math -funsafe-math-optimizations -fsingle-precision-constant
endif

(4) Build
[root@rcmp-r03 OpenNI2-BuildSystem]# cd ../../..
[root@rcmp-r03 OpenNI2-develop]# make                             20-30 minites

(5) Packaging 
[root@rcmp-r03 OpenNI2-develop]# cd Redist
[root@rcmp-r03 Redist]# vi Redist.py
