Hello there,

I try to compile my first GTK+2 code "base.ml" taken from the GTK Ocaml tutorial
from

-------------
(* file: base.ml *)

let main () =
let window = GWindow.window () in
window#show ();
GMain.Main.main ()

let _ = main ()
-------------------
You can compile the above program with ocamlc using:

ocamlc -I +lablgtk2 -o base lablgtk.cma gtkInit.cmo base.ml

HOWEVER when I do that i get the following error message

File "base.ml", line 4, characters 15-29:
Unbound value GWindow.window

anyone got any idea what it is ?
thanks

It seems that you don't have lablgtk2 installed.
Please check whether $(OCAMLLIB)/lablgtk2 exists or not.

It is likely that lablgtk2 is not correctly installed on your system.
Did you checked for gWindow.cmi in `ocamlc -where`/lablgtk2 for instance?

To check your lablgtk2 installation, you can also try to launch the
lablgtk2 toplevel, with the "lablgtk2" command. Then you can type in the
sample code above directly in the toplevel. (But it is likely that
you'll get the same error message, since it means that gWindow.cmi is
not found).
