[Not sure whether to use Gambit or Snow list - hope duplication not a problem] I have just installed Gambit (4.0.1), Termite (tarball) and Snow (1.1.1). Things seem OK, in that the following works:
gsi Gambit v4.0.1
(self) #<thread #1 primordial>
So I then defined the following in a Snow package: (cond-expand (gambit (define (acu-pmap f lst) (let ((parent (self))) (map (lambda (pid) (recv ((,pid reply) reply))) (map (lambda (x) (spawn (lambda () (! parent (list (self) (f x)))))) lst))))) (else (define (acu-pmap f lst) (map f lst)))) However, when I try to use code that calls acu-pmap I get the error (line 30 is the "let"): *** ERROR IN ac-utils/v1#acu-pmap, "ac-utils.scm"@30.20 -- Unbound variable: ac-utils/v1#self Can anyone suggest why this doesn't work and/or how I can fix it? Thanks, Andrew
