hi, it is the first time that i try to use gnat-glade and compiling an example
i got this from gnatdist :

gnatdist: building controller caller stubs from controller.ads
distribution feature not supported
compilation abandoned
gnatdist: /usr/bin/gnatgcc failed
gnatdist: *** can't continue

I use debian sarge, gnat 3.15p-7 gnat-glade3.15p-2.
