I managed to fix my linking error by adding lablgnomecanvas.cma to my compile line
However, now I have another problem; I'd like to add widgets to a gnome canvas and have them resize automatically. Furthermore, I want to move my widgets around the canvas

this is my first attempt:

(* compiled with ocamlc -I +lablgtk2 lablgtk.cma lablgnomecanvas.cma gtkInit.cmo test.ml*)
open Gobject
let _ =
let source_window = GWindow.window () in
let buffer = GText.buffer () in
let view = GText.view ~buffer:buffer ~show:true () in
let canvas = GnoCanvas.canvas ~show:true ~packing:source_window#add () in
let item = GnoCanvas.widget ~widget:view ~width:100.0 ~height:100.0 canvas#root   in
    buffer#insert "some text";
    source_window#show ();
    source_window#maximize ();
    GMain.Main.main ()


unfortunately, the size of the widget is fixed. I can resize it with item#set [`HEIGHT 50.0], but there's no way of knowing the widget's natural size (or is there?) this is my second attempt:

open Gobject
let _ =
let source_window = GWindow.window () in
let buffer = GText.buffer () in
let canvas = GnoCanvas.canvas ~show:true ~packing:source_window#add () in
let _ = GText.view ~buffer:buffer ~show:true ~packing:canvas#add () in
    buffer#insert "some text";
    source_window#show ();
    source_window#maximize ();
    GMain.Main.main ()

So now my widget (created with GText.view) resizes automatically, but I can't move it around! in fact, canvas#root#get_items is empty! Is there any way out of the conundrum?
