[Gsll-devel] MAKE-SYMBOL-FROM-STRINGS does the wrong thing?
by Zach 03 Mar '08

03 Mar '08

Okay, so this is my first post, so I may be completely misguided, After loading asdf loading GSLL, I find that I cannot do any matrix or permutation stuff with it, unless I did it from withing the package itself. After a while I tracked this to MAKE-SYMBOL-FROM-STRINGS (init/utility.lisp) which interns symbols on the fly. The problem is that it creates symbols in whatever package you happen to be in when it is called. This matters because it is used create class name symbols which should be in the package GSLL not where ever I happen to be using GSLL from. For example: (gsl:letm ((perm-1 (gsl:permutation 4 t))) (gsl:set-identity perm-1) (gsl:maref perm-1 2) ) ==> Error: There is no class named GSL-PERMUTATION. (use-package :gsll) (gsl:letm ((perm-1 (gsl:permutation 4 t))) (gsl:set-identity perm-1) (gsl:maref perm-1 2) ) ==> Error: There is no class named GSL-PERMUTATION. So I think we want to change... (defun make-symbol-from-strings (&rest strings) "Construct a symbol by concatenating words with hyphens." (intern (format nil "~{~:@(~a~)~^-~}" (mapcar #'string strings)))) ...to... (defun make-symbol-from-strings (&rest strings) "Construct a symbol by concatenating words with hyphens." (intern (format nil "~{~:@(~a~)~^-~}" (mapcar #'string strings)) :gsll)) With the change the test works (returns 2). What do you think? Zach

[Gsll-devel] Bug with image
by Jason Nielsen 01 Mar '08

01 Mar '08

First of all, thank you for making these bindings available. They are great! Much better that the bare-bones cffi wrappers I've been using for the small subset of gsl I've needed. I think there is a small bug with exceptions in the code. I usually make my own image with code that I use regularly (sbcl 1.0.14), i.e. (require 'asdf) (require 'asdf-install) (require 'cffi) (require 'gsll) (sb-ext:save-lisp-and-die "sbcl-with-slime.core") then start up sbcl with "sbcl --core sbcl-with-slime.core". In this mode of operation gsll hangs when an exception is caught, e.g. (jacobian-elliptic-functions 0.61802d0 1.5d0) just sits and the repl prompt is not returned (endless loop or something). If I just fire up sbcl and load gsll normal everything works fine and I get the expected warning that |m|>1. Hope this is a useful enough description of the problem for you to track it down. With kind regards, Jason
