ubuntu14.04 安装openNI2

1.安装 OpenNI2依赖项

1. $sudo apt-get install -y g++ python libusb-1.0-0-dev freeglut3-dev doxygen graphviz  
2. $sudo apt-get install libudev-dev  

2.从github将openni2源码clone下来

1. $git clone https://github.com/occipital/OpenNI2.git  
2. $cd OpenNI2  

3.修改两处配置Platform.Arm和CommonCppMakefile，适用于arm设备

1. $gedit ThirdParty/PSCommon/BuildSystem/Platform.Arm  

Change:

CFLAGS+= -march=armv7-a -mtune=cortex-a9 -mfpu=neon -mfloat-abi=softfp#-mcpu=cortex-a8

to:

CFLAGS+= -march=armv7-a -mtune=cortex-a15 -mfpu=neon-vfpv4 -mfloat-abi=hard

1. $gedit ThirdParty/PSCommon/BuildSystem/CommonCppMakefile

4.修改makefile，增加sample，即在makefile文件末尾添加：

1. core_samples: $(CORE_SAMPLES)  
2. tools: $(ALL_TOOLS)  

5.编译

1. $make  
2. $make core_samples # this probably isn't necessary, they should already be built  
3. $GLUT_SUPPORTED=1 make tools#GLUT_SUPPORTED tells the make to compile NiViewer for OpenGL
