Hello John,

I aim to build the GTKAda bindings with the fixed version of GTK for macOS 12.
I dig in my building configuration without success.
In fact the issue is coming from my Ada compiler which is stuck to macOS 11, the internal compilation is done 
with -mmacosx-version-min=11.0.0.

So I got:
otool -l /usr/local/xnadalib-2021/lib/gtkada/gtkada.relocatable/gtkada/libgtkada.dylib
      cmd LC_BUILD_VERSION
  cmdsize 32
 platform 1
    minos 11.0
      sdk 10.17

Thus the warning.

The test program is nevertheless running but fails with:
Gtk:ERROR:../../../../gtk+-3.24.30/gtk/gtkiconhelper.c:494:ensure_surface_for_gicon: assertion failed (error 
== NULL): Failed to load /usr/local/xnadalib-2021/share/icons/Adwaita/24x24/status/image-missing.png: 
Unrecognized image file format (gdk-pixbuf-error-quark, 3)
Bail out! Gtk:ERROR:../../../../gtk+-3.24.30/gtk/gtkiconhelper.c:494:ensure_surface_for_gicon: assertion 
failed (error == NULL): Failed to load 
/usr/local/xnadalib-2021/share/icons/Adwaita/24x24/status/image-missing.png: Unrecognized image file format 
(gdk-pixbuf-error-quark, 3)

However the GTKAda source code is the same since I built it on macOS 11 with success.

Well now, should I specify setup_sdk(target="11") in jhbuildrc-custom and rebuild all GTK stuff?

Thanks for your advice, Pascal.
