Hi all,

When I try building from the tip of default I get :

    CXX libgui/graphics/libgui_graphics___init_qt___la-

libgui/graphics/QtHandlesUtils.cc: In function ‘octave_scalar_map

                                                 ^~~~~~~~~~

Is it still supposed to be possible to build with Qt4 ?  (I have Qt
4.8.)

Hi Julien,

This was discussed in thread
http://lists.gnu.org/archive/html/octave-maintainers/2019-03/msg00041.html

Thank you Torsten.

I read the thread but the last email says "If we drop checking for Qt 4..." and "If we come to a consensus on this..." so I don't know what the actuall conclusion is.

Currently, configure silently accepts my configuration (with Qt4) but then make fails.

If Qt4 support was actually dropped, I should file a bug report concerning the build system.  If Qt4 is still supported, I should file a bug report concerning the above issue with angleDelta.

Which one is it ?
