Re: [Vala] .typelib support in Vala

Thanks for the quick reply, Evan.  To answer some of your questions:

Sometimes you may have to install an extra package, but the GIRs should

I'll probably open a ticket with Ubuntu about this.

You should pass the pkg-config names of whatever dependencies you need 
to valac. valac will parse those VAPIs first, and there is an 
annotation which will tell valac what GIR namespace the Vala namespace 
corresponds to.

At first I thought you'd figured it out, but I'm still seeing the problem.  The .gir file in question has 
these annotations inside it:

<include name="GLib" version="2.0"/>
<include name="GObject" version="2.0"/>
<include name="Gio" version="2.0"/>

To see my problem, rename GLib-2.0.gir.  I use a simple Vala program (Vala 0.17.5 installed):

void main() {
}

If I build like this, no problem:

valac test.vala --pkg=glib-2.0 --pkg=gobject-2.0 --pkg=gio-2.0

If I build like this, I get the error messages I mentioned earlier:

valac test.vala --pkg=glib-2.0 --pkg=gobject-2.0 --pkg=gio-2.0 --pkg=DBusGLib-1.0

I do see the VAPI annotations in the glib-2.0.vapi file (and the others), but it looks like valac isn't 
properly making the connection you mentioned.
