Re: Making chaos system - errors

[Alfred M. Szmidt]

   It would appear that the CONVERSE system needs to be loaded in
   order to get the ZWEI::CONVERSE-FRAME flavor loaded — which would
   resolve the first error.

   It would appear that the FED system needs to be loaded in order to
   resolve the second error.

   It would appear that the ZMAIL system needs to be loaded in order
   to resolve the third.

Yes, and you probobly also want CADR loaded too to reduce even more
warnings.

   The error in CHAOS comes from this function:

Why do you think it is an error?  Looks like a warning.

   (DEFUN USER-ACTIVITY-STRING ()
     (LET ((W (DO ((W TV:SELECTED-WINDOW (SEND W :SUPERIOR))
   (W1 NIL W))
         ((OR (NULL W) (TYPEP W 'TV:SCREEN)) W1))))
       (OR (IGNORE-ERRORS
    (TYPECASE W
      (SUPDUP "Supdup")
      (ZWEI:ZMACS-FRAME "Zmacs")
      (TV:PEEK-FRAME "Peek")
      (ZWEI:CONVERSE-FRAME "Converse")
      (TV:INSPECT-FRAME "Inspect")
      (TV:LISP-LISTENER "Lisp")
      (TELNET "Telnet")
      (FED:FED-FRAME "Font Edit")
      (ZWEI:ZMAIL-FRAME "ZMail")))
   SI:LOCAL-HOST-NAME)))

   I wonder if this code can be written in another way such that the
   compiler will not have to know about these types at compile time,
   but rather at runtime. Seems that the issue is that the compiler
   checks the types used in TYPECASE, and therefore those types have
   to be defined.

I don't think it is worth it.  When dumping a full system all those
will vanish since we should have CONVERSE, ZMail, etc loaded.

What we are doing is a sub-set cause we are lazy, and it makes it much
faster to do things.
