[Matlisp-users] Using --with-atlas with sbcl

[Jose A. O. R. <ja...@gn...>]

Hi. As a result of a conversation with rtoy at #lisp, I've noticed
that lazy-loader.lisp is not loading libblas&c. when configure
=2D-with-atlas is used with sbcl. This quick hack of
load-blas-&-lapack-libraries works for me:

#+:sbcl
(defun load-blas-&-lapack-libraries ()
  #+@ATLAS_P@ (sb-alien:load-shared-object "@ATLAS_DIR@/libblas.so")
  #+@ATLAS_P@ (sb-alien:load-shared-object "@ATLAS_DIR@/liblapack.so")
  #(not @ATLAS_P@) (sb-alien:load-shared-object "matlisp:lib;libmatlisp.so"=
))

HTH,
jao

Thanks for the patch.

I think that to make this work right, I'll have to add another option
--enable-shared-atlas because not all platforms have shared atlas
libraries.   

I'll have to play around a bit with this, though.  I've kind of
forgotten exactly what libs are needed to build matlisp with ATLAS.
