I have obtained Qt5Ada from AdaStudio last July but have lost track of whic=
h website I obtained it from.
I am using a Mac OSX 10.13.6
I have built the library successfully. It generated libQtada_Lib.a.
However, I am having trouble linking the first demo. =20
It compiles OK.
I tried changing the QT version to:
Version_QAda    : string(1..6) :=3D "5.12.0";
QT_VERSION      : constant Integer :=3D  16#050C00#;
which compiled OK.

Its failing with:
Undefined symbols for architecture x86_64:
  "_QApplication_create", referenced from:
      _qt__qapplication__qapplication_create__2 in libQtada_Lib.a(qt-qappli=
cation.o)
  "_QApplication_destroy", referenced from:
      _qt__qapplication__qapplication_invoke in libQtada_Lib.a(qt-qapplicat=
ion.o)
      _qt__qapplication__qapplication_invoke__2 in libQtada_Lib.a(qt-qappli=
cation.o)
plus numerous others

My gpr file:
with "../../../../qt5ada.gpr";

project Simple is

   for Source_Dirs use ("SimpleExample");
   for Object_Dir use "obj";
   for Main use ("mywindow.adb");

   package Linker is
      for Switches ("ada") use ("-F/usr/local/Cellar/qt/5.12.0/lib", "-fram=
ework", "QtWidgets", "-framework", "QtGui", "-framework", "QtCore", "-frame=
work", "DiskArbitration", "-framework", "IOKit", "-framework", "QtMacExtras=
", "-framework",=20
         "OpenGL", "-framework", "AGL", "-L/Ada_Source/AdaStudio/qtada/lib"=
, "-lQtada_Lib");
   end Linker;

end Simple;

I added the "-L/Ada_Source/AdaStudio/qtada/lib", "-lQtada_Lib" but this did=
n't fix the problem.

Any assistance will be appreciated,
Roger
