[cells-gtk-devel] cells-gtk newbie problem no 1: style warning "can't find type for specializer MY-APP" when compiling defmodel

[Johan Ur Riise]

I have installed cells via asdf-install, and cells-gtk from cvs. My lisp is 
SBCL 1.0.10.33

This program just displays a top-level window with no functionality. The 
test-gtk program from the distribution does not have this problem, but in 
that case the symbol test-gtk is used for the asdf system-name. 
Program follows, then the full error message. If I compile again, there is no 
warnings.

(require 'cells-gtk)

(defpackage :my-package
  (:use :common-lisp :pod :cells :gtk-ffi :cells-gtk)
  (:export RUN-MY-APP) )

(in-package :my-package)

(defmodel my-app (gtk-app)
  ()
  (:default-initargs))

(defun run-my-app (&optional dbg)
  (cells-gtk-init)
  (cells-gtk:start-app 'my-app :debug dbg))
