#ifndef FLTK_GUARD
#define FLTK_GUARD 1

#include "FL/Fl.H"
#include "FL/Fl_Window.H"
#include "FL/Fl_Button.H"
#include "FL/Fl_Input.H"

this worked for me
On your own Linux/Mac: Download the source for fltk 1.1.10 and unpack it in a directory of your choice. You should be able to execute "configure", "make", and "sudo make install" to install fltk in /usr/local/lib and /usr/local/include.
