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.
