Package: maxima
Version: 5.33.0-2
Severity: normal
Dear Maintainer,
In my system, Maxima cannot load Lapack. It fails after showing
this error message:
Finished loading
/home/jeronimo/.maxima/binary/binary-gcl/share/lapack/lapack/zheev.o
Compiling /usr/share/maxima/5.33.0/share/lapack/eigensys.lisp.

loadfile: failed to load /usr/share/maxima/5.33.0/share/lapack/load-lapack.lisp
-- an error. To debug this try: debugmode(true);
So, it seems that the number "2" was used as a variable name (or
prefix of a variable name), and GCL did not like it.
Fixing this is easy: the file
/usr/share/maxima/5.33.0/share/lapack/eigensys.lisp
defines a function called "lapack-maxify-matrix". In this
function, there is a temporary variable called "2d".
It is defined once and used only once. Change its name
to "two-d" and Maxima is able to load lapack.
Thank you,
Jerônimo
PS: here is the function, for reference:
(defun lapack-maxify-matrix (nrow ncol a)
"Convert an LAPACK matrix of dimensions NROW and NCOL into a Maxima
matrix (list of lists)"
(let ((2d (make-array (list ncol nrow) :element-type (array-element-type a)
:displaced-to a)))
(let (res)
(dotimes (r nrow)
(let (row)
(dotimes (c ncol)
;; Fortran arrays are column-major order!
(let ((v (aref 2d c r)))
(push (add (realpart v) (mul '$%i (imagpart v))) row)))
(push `((mlist) ,@(nreverse row)) res)))
`(($matrix) ,@(nreverse res)))))
