Build GTK+ application in Ada - GtkAda

I'm trying to develop to the first time a GTK+ application in Ada, with GtkAda. I installed it, and I could build a Hello World application from the "Simple Window" template proposed by GPS.

But, when I want to run it, I become an error popup with this message:

"gdk_device_get_last_event_window" could not be found in the DLL "[path_to_my_project]\obj\main.exe".

It was linked with the static library. If I try to link with the relocatable library (using GPS scenario variable LIBRARY_TYPE), I got almost the same error:

"gdk_cairo_surface_create_from_pixbuf" [...]

This second error appears too if I try to launch sample applications (testgtk.exe or test_rtree.exe) from [gtkada_dir]\share\examples\gtkada\testgtk.

So, did I missed something at the installation of GtkAda?

I run Windows 8.1, I installed GtkAda into the default folder (C:\GtkAda - note I tried to install it into C:\GNAT\2016 too, but the problem is the same).

My PATH includes C:\GtkAda\bin;C:\GtkAda\lib, I added another environment variable ADA_PROJECT_PATH=C:\GtkAda\lib\gnat.

I installed Gnat from the latest version (20160515-49).

Any idea to get GtkAda applications running?

Thanks for your help.

I find that GtkAda works best with GNAT in Windows when installed in the GNAT directory. In the case of your installation that should be C:\Gnat\2016. Also make sure you add the following line to the beginning of your project file:

with "gtkada";
