Hi,

This appears again to be an inconsistency between
configure and make check on OSX:

When running configure FLTK and OpenGL appear
to be correctly detected [1]:


checking for fltk-config... /usr/local/bin/fltk-config
checking for OpenGL support in FLTK... yes


but, when running 'make check' all tests related to the
fltk toolkit fail [2]:


***** testif HAVE_OPENGL, HAVE_FLTK
 hf = figure ("visible", "off");
 graphics_toolkit (hf, "fltk");
 unwind_protect
   subplot(2,1,1); plot(rand(10,1)); subplot(2,1,2); plot(rand(10,1));
   hax = findall (gcf (), "type", "axes");
   positions = cell2mat (get (hax, "position"));
   outerpositions = cell2mat (get (hax, "outerposition"));
   looseinsets = cell2mat (get (hax, "looseinset"));
   tightinsets = cell2mat (get (hax, "tightinset"));
   subplot(2,1,1); plot(rand(10,1)); subplot(2,1,2); plot(rand(10,1));
   hax = findall (gcf (), "type", "axes");
   assert (cell2mat (get (hax, "position")), positions, 1e-4);
   assert (cell2mat (get (hax, "outerposition")), outerpositions, 1e-4);
   assert (cell2mat (get (hax, "looseinset")), looseinsets, 1e-4);
   assert (cell2mat (get (hax, "tightinset")), tightinsets, 1e-4);
 unwind_protect_cleanup
   close (hf);
 end_unwind_protect
!!!!! test failed
graphics_toolkit: fltk toolkit is not available


the message about missing fltk toolkit seems inconsistent
with HAVE_FLTK evaluating to true ...
