[Vala] Issue with TypeInterface in a gir file

[Emmanuel Pacaud <emmanuel gnome org>]

Hi,

I'm developing a gobject based library, in C, which already has
gobject-introspection support.

http://git.gnome.org/browse/aravis/commit/

I'm now trying to write a simple test of the introspection support,
using vala (0.7.10).

The valac command line looks like this:

/usr/bin/valac  --girdir=. --pkg Aravis-1.0 --pkg gtk+-2.0 -C aravis.vala

But I get the following error:

error: The type name `GLib.TypeInterface' could not be found
error: The type name `GLib.TypeInterface' could not be found
error: The type name `GLib.TypeInterface' could not be found
Compilation failed: 3 error(s), 0 warning(s)

I guess valac fails on the following lines in Aravis-1.0.git:

    <record name="ArvGcIntegerInterface"
            c:type="ArvGcIntegerInterface"
            glib:is-gtype-struct-for="ArvGcInteger">
      <field name="parent">
        <type name="GObject.TypeInterface" c:type="GTypeInterface"/>
      </field>
      <field name="get_value">
        <callback name="get_value" c:type="get_value">
          <return-value transfer-ownership="none">
            <type name="int64" c:type="gint64"/>

But I don't know why. Any idea ?

Thanks in advance,

Emmanuel.
