- I have further information about my problem it has something to
- do with the aref setup for lucid....
-
- The following was mentioned in the CHANGES file for CLX
-
- o In Lucid lisp, the functions aref-card8, aref-int8, aset-card8,
- aset-int8, aref-card16, aref-int16, aref-card32, aref-int32,
- aref-card29, aset-card16, aset-int16, aset-card32, aset-int32,
- and aset-card29 Have been fixed so that they can be used inline
- with the development compiler.
-
- **but in the dependents.lisp file there is the following:
-
-
- (declaim (inline aref-card8 aset-card8 aref-int8 aset-int8))
-
- #-(or Genera lcl3.0 excl akcl)
- (progn
-
- (defun aref-card8 (a i)
- (declare (type buffer-bytes a)
- (type array-index i))
- (declare (values card8))
- #.(declare-buffun)
- (the card8 (aref a i)))
- .
- .
- .
-
- **then later
-
-
- #+lcl3.0
- (progn
-
- (defun aref-card8 (a i)
- (declare (type buffer-bytes a)
- (type array-index i)
- (values card8))
- #.(declare-buffun)
- (the card8 (lucid::%svref-8bit a i)))
-
- (defun aset-card8 (v a i)
- (declare (type card8 v)
- (type buffer-bytes a)
- (type array-index i))
- #.(declare-buffun)
- (setf (lucid::%svref-8bit a i) v))
-
- .
- .
- .
-
-
- **but when I try to compile it I get:
-
- ;;; You are using the compiler in development mode (compilation-speed = 3)
- ;;; Generation of runtime error checking code is disabled (safety = 0)
- ;;; Optimization of tail calls is enabled (speed = 3)
- ;;; Reading source file "dependent.lisp"
- >>Error: LUCID::%SVREF-8BIT is not a known location specifier for SETF.

- ***Also note I had this working until reciently, though I am not sure why
- it stopped working, we had
-
- "The X11R5 binaries and libraries have been updated after patch #17
- (previously, we were only at patch #12)"
-
- at the same time though I cannot see how this would be causing
- the error!!!!!!
-
-
- If anyone can help, or are able to tell me who wrote CLX (there is
- no note in the documentation), it be very much appreciated....
-
- Thanks Tony Travers
