‘FL_NORMAL_SIZE’ does not name a type

    Make sure you've got:

        #include <FL/Fl.H>
    ..at the top of your program.

Fl_Fontsize FL_NORMAL_SIZE = 11;

    Yea, no, don't do that. That just tries to /create/ another global variable of the
    same name as the one in FLTK, and fails at link time with the conflict.

    Here's a complete program showing where you should put what:

#include <FL/Fl.H>#include <FL/Fl_Window.H>#include <FL/Fl_Button.H>#include <FL/Fl_Box.H>int main(int argc, char **argv) { FL_NORMAL_SIZE = 20; Fl_Window *window = new Fl_Window(340, 180); new Fl_Button(20, 40, 300, 50, "Hello World!"); new Fl_Box(   20, 100, 300, 50, "Some text."); window->end(); window->show(); return Fl::run();}
    If you change the value for FL_NORMAL_SIZE to something else, that should affect
    the size of all fonts.
