once i got the same error. then i changed the order of include files
then it worked.
in my case, previous
#include <FL/Fl.H>
#include <FL/Fl_Double_Window.H>
#include <FL/fl_ask.H>
#include "general.h"
#include <FL/Fl_File_Chooser.H>
ths order gives me the same error.
then i changed it to
#include <FL/Fl.H>
#include <FL/Fl_Double_Window.H>
#include <FL/Fl_File_Chooser.H>
#include <FL/fl_ask.H>
#include "general.h"
then it worked.
