Primitive line strip and loop Not working

Hi ! Im new at openframeworks and Im trying to learn how to mesh with this tutorial :
http://openframeworks.cc/tutorials/graphics/generativemesh.html
Im having the problem that when I tryed :

mesh.setMode(OF_PRIMITIVE_LINE_STRIP);
mesh.setMode(OF_PRIMITIVE_LINE_LOOP);

wont work, allthought :

 mesh.setMode(OF_PRIMITIVE_LINES); works just fine. 

Im getting this error :

 src/ofApp.cpp|5|error: ‘OF_PRIMITIVE_LINES_LOOP’ was not declared in this scope|

the same thing happens with OF_PRIMITIVE_LINE_STRIP

OF_PRIMITIVE_LINES_LOOP is a typo I believe – should be OF_PRIMITIVE_LINE_LOOP

Valid values are:

OF_PRIMITIVE_TRIANGLES,
OF_PRIMITIVE_TRIANGLE_STRIP,
OF_PRIMITIVE_TRIANGLE_FAN,
OF_PRIMITIVE_LINES,
OF_PRIMITIVE_LINE_STRIP,
OF_PRIMITIVE_LINE_LOOP,
OF_PRIMITIVE_POINTS
