Building OpenNI from Source on Linux

You will find lot of tutorials on building OpenNI from source on ubuntu.
I encountered only one error and had to go through number of blogs to figure it out.

Error is something like this

/usr/bin/ld: ./x64-Release/NiSimpleViewer.o: undefined reference to symbol 'glEnd'
/usr/bin/ld: note: 'glEnd' is defined in DSO /usr/lib/libGL.so.1 so try adding it to the linker command line
/usr/lib/libGL.so.1: could not read symbols: Invalid operation
collect2: ld returned 1 exit status

Solution

Goto OpenNI/Platform/Linux/Build/Samples/

In each sample try to find the line

USED_LIBS += glut

and replace it with

 USED_LIBS += glut GL

hope it helps :)
