        BTW, does the FLTK test program "message" work for you?
        If you recently built FLTK, run it.. the second dialog
        (which starts with "Quantum fluctuations") uses fl_alert()
        with %g as part of its format string.

        FWIW the following works OK with 1.3.2 on linux:

#include <FL/Fl.H>
#include <FL/Fl_Window.H>
#include <FL/fl_ask.H>
int main(int argc, char* argv[]) {
    int i = 12;
    float f = 34.56;
    const char *s = "hello world";
    fl_alert("Testing an int(%d) a float (%.2f) and a string (%s)",i,f,s);
    return Fl::run();
