GLCD was not declared in this scope ERROR

Hi I am trying to compile GLCD example programs but I get the error above. Am I missing a header file or is it in the wrong location or is there a specific location that the header files have to go in?

Need additional information. Is the for the glcd v3 library? If so, what arduino board are you using and what example sketch is causing problems? In other words, describe how to re-create the problem.
