Yep, instead of gtkada.gpr they invented gtkada2.gpr. When I use Fedora's
GtkAda I add my own gtkada.gpr and some other gpr files to keep it
consistent.

But since GNAT FSF for Fedora/Ubuntu is quite broken anyway, I would not
worry about that in your place. You better use GNAT GPL 2010 for Linux and
its GtkAda instead. BTW, the Fedora GtkAda is also outdated, when I checked
it last time. In particular pixbuf was not an gobject, if I correctly
remember. That is very nasty incompatibility. In short, see above, do not
use it.

No it does. That is C:\GtkAda\lib\gnat

1. If you are going to link using naked gnatmake, you have to add options
to the linker, like -lgtk-win32-2.0 (and whatever, the list is long).

2. If you want to use gtkada.gpr, which is preferable of course, you need
to make it available. There are many ways. One is to integrate it into the
GNAT, like win32ada is. That is a bit complicated. A simpler one is to just
add C:\GtkAda\lib\gnat to the ADA_PROJECT_PATH environment variable.
