Windows, ltk-0.96. BTW, I teaching Common LISP for engineers, and using ABLE/SBCL. However, since ABLE does not compile out of the box, I am distributing binaries to the my students. It would be nice if you people could fix the compilation problems that I describe below. 1 -- able-0.21, SBCL 1.0.52, ltk-0.96, cl-fad-0.6.4, trivial-gray-streams-2008-11-02 2 -- I tried to compile and load the programs: * (require 'asdf) ("ASDF") * (asdf:oos 'asdf:load-op :able) ... debugger invoked on a ASDF:COMPILE-ERROR: Error while invoking #<COMPILE-OP NIL {24D9CEB9}> on #<CL-SOURCE-FILE "able" "utils"> 3 -- I substituted sb-introspect:function-lambda-list for all instances of sb-introspect:function-lambda-list I also corrected the obvious error (format nil "1.0" temp) 4 -- I repeated step 2. * (require 'asdf) ("ASDF") * (asdf:oos 'asdf:load-op :able) Compilation was uneventful, but I got a runtime error ---- Invalid intialization arguments: :PADY, :PADX, :CONTAINER In main.lisp, I replaced (setf *editor-frame* (make-instance 'ltk:frame)) for (setf *editor-frame* (make-instance 'ltk:frame :container nil :padx 1 :pady 1)) I compiled the editor once more: * (require 'asdf) ("ASDF") * (asdf:oos 'asdf:load-op :able) Again, the compilation was uneventful, but... Invalid initialization arguments :PADY, :PADX I substituted (setf *listener* (make-instance 'listener )) for (setf *listener* (make-instance 'listener :padx 1 :pady 1)) This time the error was Tcl/Tk error: unknown option "-background" I commented one line at the end of the controls.lisp file: (defmethod initialize-instance :after ((sb statusbar) &key) (setf (label sb) (make-instance 'ltk:label :master sb :font *buffer-font*)) ; (ltk:configure sb :background *highlight-background*) (ltk:configure (label sb) :background *highlight-background* :foreground *highlight-text*) (ltk:pack (label sb) :side :left :pady 1 :padx 5 :fill :both)) Now, ABLE works perfectly well. My suggestion is that you modify the sources, so that the user get an uneventful compilation. In the mean time, I would like to know whether I can post my modified sources in my son's website, so my students will have a working copy of ABLE. Of course, I will remove it from my site as soon as the official distribution is fixed.
