No, I'm using the latest svn. svn diff shows no differences with my
stuff. I looked at the source code and I know that it is broken and why
that is.

Okay. Here's the difference. You are getting fltk2_images. That's
clearly not what happens with latest SVN.
Greg sets --use-images in the main makefile, but not in the
Makefile-fltk2, which is obviously a problem if you run it alone without
the switch, but regardless of that latest svn of fltk2-config is broken.
If you look at fltk2-config.in (or fltk2-config latest), you will see this:
if test x$use_images = xyes; then
LDLIBS="-lfltk2_images$SHAREDSUFFIX $IMAGELIBS $LDLIBS"
LDSTATIC="$libdir/libfltk2_images.a $LDSTATIC $IMAGELIBS"
fi
That is, unlike other switches, LIBS is not being set for --use-images.
However, later this is the stuff printed.
if test "$echo_libs" = "yes"; then
echo $LIBS
fi
Thus, the libfltk2_images is never printed, regardless of switch. Even
if you fix that, you will still get a reference problem due to the order
of libs and libfltk2_images appearing twice. It is several bugs in
fltk2-config.in and configure.in, which has this unneeded crap in it:
IMAGELIBS="-lfltk2_images"
instead of:
IMAGELIBS=""

To further test how much fltk2-config is broken, try this:
> fltk2-config --libs
> fltk2-config --use-images --libs
> fltk2-config --ldflags
> fltk2-config --ldstaticflags
> fltk2-config --ldflags --libs
> fltk2-config --ldstaticflags --libs
> fltk2-config --ldflags --use-images --libs
> fltk2-config --ldstaticflags --use-images --libs
If your fltk2-config is correctly coded, it should return (on linux):
> fltk2-config --libs
-lfltk2 -lX11 -lXi -lXinerama -lXft -lpthread -lm -lXext -lsupc++
> fltk2-config --use-images --libs
-lfltk2_images -lpng -ljpeg -lz -lfltk2 -lX11 -lXi -lXinerama -lXft
-lpthread -lm -lXext -lsupc++
> fltk2-config --ldflags
-Wl,-rpath,/usr/local/lib -L/usr/local/lib
> fltk2-config --ldflags --libs
-Wl,-rpath,/usr/local/lib -L/usr/local/lib -lfltk2 -lX11 -lXi -lXinerama

> fltk2-config --ldstaticflags --libs
-L/usr/local/lib /usr/local/libfltk2.a -lX11 -lXi -lXinerama -lXft
-lpthread -lm -lXext -lsupc++
> fltk2-config --ldstaticflags --use-images --libs
-L/usr/local/lib /usr/local/libfltk2_images.a /usr/local/libfltk2.a
-lX11 -lXi -lXinerama -lXft -lpthread -lm -lXext -lsupc++
Notice that: fltk2_images should appear only once and that it does not
appear without the --use-images.
Also, try using --ld-flags and --ldstaticflags and not using either
flag. On latest SVN the ONLY way to get the libs is by using
--ld-flags, which is obviously incorrect. That should only print the
flags, not add new libraries or repeat them.
With svn fltk2, --use-images switch does nothing without some other flag
triggering the printing.
The versions I posted fixes some problems and is simpler, too, albeit
looking even more at fltk2-config, I realize I did not fix all the issues.
