In the Debian Policy for Ada, I strongly recommend you use a project
file for your program.  Since you use GtkAda, look at the comments in
/usr/share/ada/adainclude/gtkada2.gpr: these will tell you how to
write your own project file.

If you follow these guidelines and still have problems, that would be
a good time to start posting detailed error messages so we can help
you further.

As for the OpenGL component: it requires not only libgtkada-gl-2.8
(which you probably have installed already) but also it requires
hardware support depending on your particular graphics card, the
proper display driver, and the Mesa libraries (which you probably have
installed already, since libgtkada-gl-2.8 depends on them).  If OpenGL
is critically important to you, tell us about your hardware.  You may
also be interested in http://dri.freedesktop.org/wiki/.
