Hi all, While working through the first bits of the HtDP2e book, in DrRacket 6.9 on Mac, I get the following error whenever I try to run any program in the "Definitions" window that contains (require 2htdp/universe):
link: bad variable linkage; reference to a variable that is not a procedure or structure-type constant across all instantiations reference phase level: 0 variable module: "/Applications/Racket v6.9/share/pkgs/string-constants-lib/string-constants/string-constant.rkt" variable phase: 0 reference in module: "/Applications/Racket v6.9/share/pkgs/htdp-lib/2htdp/private/world.rkt" Googling the error didn't help me out, and I'm afraid I'm too much of a noob right now to understand what's going on. What's more, I'm really sure this worked fine a few days ago. Restarting DrRacket doesn't help either. Any suggestions would be most welcome! Thanks in advance :-) Best regards, Onno -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
