At this I have the following GdaSqlAnyPart declaration as:

GdaSqlAnyPart *parent;

In libgda-4.0.vapi we have:
[Compact]
[CCode (cheader_filename = "libgda/libgda.h")]
public class SqlAnyPart {
public weak Gda.SqlAnyPart parent;
public Gda.SqlAnyPartType type;
public bool check_structure () throws GLib.Error;
public bool @foreach (Gda.SqlForeachFunc func, void* data) throws
GLib.Error;
}
Do I need a metadata information to "tell" vapigen to use <weak
Gda.SqlAnyPart> as the type of parent to avoid recursive?
The problem is that while in libgda-4 it was a compact class, the gir says it's a <record> which is a struct. There's no metadata currently to force a struct to become a class: if you report a bug I can take care of it, should be trivial. -- http://www.debian.org - The Universal Operating System
