Hi John,

I'm running Octave with fltk/GL a few days now. It was a little bit tricky to 
make the fltk/GL libs working, but now I have a nice FLTK window displaying graphs.

I downloaded two new source packages that we need on MacOSX -> fltk 1.1.9 and 
ftgl 2.1.2. I compiled both from source against MacOSX's OpenGL libs.

For fltk I had to use the configure flags "--enable-shared --enable-quartz 
--enable-gl" - I also tried other flags but without better results. I also 
needed to remove the optimization flag "-ftree-vectorize" from my 
C-,CPP-,CXXFLAGS - with this flag the fltk/GL engine doesn't work. No changes 
necessary for LDFLAGS here. Once you have compiled fltk, make sure that in the 
fltk/test directory the programs gl_overlay and glpuzzle display the graphs - 
otherwise you won't have a chance to compile fltk/GL with Octave.

For ftgl I had to call "autoreconf" before "configure". I also needed to add 
"-I/usr/X11R6/include" to my C-,CPP-,CXXFLAGS and "-framework OpenGL" to my 
LDFLAGS. Then the steps configure, make, make install work very well.

Finally, I also added "-I/usr/X11R6/include" to my C-,CPP-,CXXFLAGS before 
configuring the Octave sources and "-Wl,-framework -Wl,OpenGL" to the LDFLAGS. I 
must say here that I haven't tried to configure the Octave sources without these 
flags - I think I must check this out, ideally they should automatically be 
found by the configure script on a Mac system.

Once compiled everything, I had and still have a problem resizing the figure 
window, but I'm already in contact with Shai about that. I think there is still 
a bug in the fltk sources but I currently cannot really figure out the problem - 
so help is wanted ;)

But that's it already, all the sources are ok and can be compiled without error 
as long as the dependencies do work pretty. The window appears and display of 
the fltk/GL window is really great, thanks to Shai and Michael,

Regards,
