You can use the gtkada-config script to get the required compiler and 
linker arguments:

gnatmake test01 `gtkada-config`

Alternatively, you can 'with "gtkada"` in your .gpr file, as discussed here:

<http://stackoverflow.com/a/7464775/230513>

Both approaches are covered in "Getting started with GtkAda":
