]> Hello I created 2 files : point.ml and point.mli. The first one contained a simple class definition. class point = object value mutable x = 0; method addunit v = v+1 ; end; The second one contained class type point = object value mutable x : int; method addunit : int -> int ; end; I used this class in another file, test.ml which contained open Point; value parse t = match t with [ "" -> let a = new point in () | _ -> () ]; My compilation command was: ocamlopt -pp "camlp4r pa_extend.cmo" -I +camlp4 -c point.mli point.ml test.ml However, on compilation I got an error message: File "t2.ml", line 4, characters 18-27: Unbound class point make: *** [code] Error 2 I am not able to create a new point object from outside the file. Could you help me solve this problem ?
