This suggests that the graphical user interface is missing. Do you have
the lablgtk library installed? If not, neither why nor frama-c will
complain (you can see a warning about lablgtk in config.log though), but
they will only build the command-line tools. If you have some provers
installed (e.g. alt-ergo), you can directly select one of them with
-jessie-atp <prover> (e.g. -jessie-atp alt-ergo).

Hope this helps,
