Thanks for your reply, but unfortunately, it really WAS the first thing I did
- but because X is not reference counted, it resulted in errors like this:
oldlib.vapi:61.33-61.36: error: duplicating X instance, use unowned variable or
explicitly invoke copy method
public static GLib.List<X> old_lib_make_x_list();
^
And I don't really want to copy the "X" structure, because it's rather large
and there are a lot of them..
Maybe I don't see something obvious, I'm still not fully comfortable in vala
and I may have missed something..
But anyway, thanks.
Regards,
Jan Spurny
