problem getting gtkada to work

problem getting gtkada to work

[Michel Simeon]

I am learning Ada and would like to use gtkAda.

I tried the exemple below, found in the web:

with Gtk.Main, Gtk.Window;
procedure Simple is
W : Gtk.Window.Gtk_Window;
begin
  Gtk.Main.Init;
  Gtk.Window.Gtk_New(W);
  Gtk.Window.Show(W);
  Gtk.Main.Main;
end Simple;

I am using Windows XP with GNAT 3.15p, AdaGIDE, and GtkAda 2.4.0

I put -IC:\GNAT\gtkada-2.4.0\include\gtkada as a compiler option in AdaGIDE
The program compiles, and then I get the following:

gnatlink -g simple.ali
:\GNAT\gtkada-2.4.0\include\gtkada\\libgtkada.a(misc.o.b)(.text+0x327f:1:
undefined reference to `SetCursorPos@8'
gnatlink: cannot call C:\GNAT\bin\gcc.exe
gnatmake: *** link failed.

I also tried to compile other exemples that come with the gtkada 
distribution and got exactly the same problem.

Could somebody help with some advise.

Have you specified -mwindows for gnatmake?

Follow this thread 
http://lists.adacore.com/pipermail/gtkada/2005-March/003268.html

In short you need to fix gtk.ads file.
Add line
   pragma Linker_Options ("-luser32");
After
private
   pragma Linker_Options ("-lgtkada");
