[Vala] DBUS warnings (I don't understand)

[Brian Duffy <brduffy gmail com>]

Hello everyone,

I have a simple dbus example working, but I am getting some compiler
warnings that I don't understand.

eg.  warning: passing argument 3 of ‘g_cclosure_new’ from incompatible
pointer type [enabled by default].

I have narrowed it down to the Bus.own_name call ...

Bus.own_name (BusType.SESSION, "org.example.Demo", BusNameOwnerFlags.NONE,
                  on_bus_aquired,
                  () => {},
                  () => stderr.printf ("Could not aquire name\n"));

Any idea what I am doing wrong?

Here is my code and compiler output ...

Thanks

Brian
