[Vala] Question about vala-gen-introspect

["W. Michael Petullo" <mike flyn org>]

I am trying to figure out how to generate a Vala API file for
libdmapsharing, http://www.flyn.org/projects/libdmapsharing/. This
library may be used to create DAAP and DPAP servers and clients. I have
read the document at http://live.gnome.org/Vala/Bindings.

I am using vala-0.10.0 and have tried the following sequence:

        mkdir libdmapsharing-2.2
        echo "include/libdmapsharing-2.2" > libdmapsharing-2.2/libdmapsharing-2.2.files
        echo "lib64/libdmapsharing.so" >> libdmapsharing-2.2/libdmapsharing-2.2.files
        echo "DMAP" > libdmapsharing-2.2/libdmapsharing-2.2.namespace
        vala-gen-introspect libdmapsharing-2.2 libdmapsharing-2.2
        vapigen --library libdmapsharing-2.2 libdmapsharing-2.2/libdmapsharing-2.2.gi

When I run "vala-gen-introspect," I get the following output:

[...]

Later, I run "vapigen --library libdmapsharing-2.2
libdmapsharing-2.2/libdmapsharing-2.2.gi" and get:

error parsing GIDL file: Error on line 1 char 1: Document must begin with an element (e.g. <book>)
Generation succeeded - 0 warning(s

The resulting libdmapsharing-2.2.vapi is empty, aside from default
heading comment.

I have not been able to find a definition of the "Unknown function
directive" error. What does this error message mean?
