It sounds very nice.
It seems that it requires a newer version of GObject (2.44+) than I have
on my system (2.42), based on its use of GListModel
G_DECLARE_FINAL_TYPE, so I can't easily compile it. I guess if we're
going to require a new Glib, then I'll have to upgrade to Debian
"testing" or "unstable". I'm willing to do that; I hope that it's not a
big deal for our users.Like you say, it needs a recent version of Glib. If and when this becomes ready for serious use in pspp, I think it likely that debian will have made a new release. In the meantime, what I did is to locally install Glib2.47 (you must also install libffi-3.2.1). J' -- Avoid eavesdropping. Send strong encryted email.
