Re: [racket-users] "Link: bad variable linkage" when trying to work through tutorial
How did you install Racket? Via the Mac installer from ‘download’?

Re: [racket-users] "Link: bad variable linkage" when trying to work through tutorial
Onno, That happens when the .zo files produced by plain command-line racket conflict with ones that come from DrRacket. Or the other way around, I am not sure. Or something else related to .zo files that are no longer valid for some reason. Anyway, try removing the 'compiled' directories from your source tree and restarting.

[racket-users] "Link: bad variable linkage" when trying to work through tutorial
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.
