It appears that the symbols used to select the various random number sample functions are not exported. I was getting "The symbol "UNIFORM" is not external in the GSLL package." when I ran the following code.
(clc:clc-require :gsll) (defparameter *rng* (gsl:make-random-number-generator gsl:+default-type+)) (gsl:sample *rng* 'gsl:uniform)
I've created a patch to merge into the git repository, but I'm not a Lisp expert, so my solution may be wrong.
Thanks to all who have contributed to this very useful library.

A related question for Liam: It seems like keywords would make more sense for the selector symbols (e.g., :uniform rather that 'gsl:uniform). Is there any particular reason that the selection symbols are in the GSL package instead?
Thanks, James

No, in fact when I first looked at this patch I wondered myself why I hadn't put them in the keyword package. I guess it was because these were originally functions with their own names, e.g. sample-uniform, so I just carried the symbol over when they became methods of #'sample. Is the consensus that they be in the keyword package?

A related question for Liam: It seems like keywords would make more sense for the selector symbols (e.g., :uniform rather that 'gsl:uniform). Is there any particular reason that the selection symbols are in the GSL package instead?
Thanks, James

It appears that the symbols used to select the various random number sample functions are not exported. I was getting "The symbol "UNIFORM" is not external in the GSLL package." when I ran the following code.
(clc:clc-require :gsll) (defparameter *rng* (gsl:make-random-number-generator gsl:+default-type+)) (gsl:sample *rng* 'gsl:uniform)
I've created a patch to merge into the git repository, but I'm not a Lisp expert, so my solution may be wrong.
Thanks to all who have contributed to this very useful library.
