I have several versions of racket installed on Ubuntu linux at default linux locations. I think I should uninstall them all. Then after downloading a PPA from the racket web site install the version I want to a single directory. (I would be downloading version: 7.8) Does this sound like a plan sound okay?
I gather from the comments I have received from John Clements, that he suspects I am having some sort of problem that is motivating the desire to return to an earlier version of Racket. I believe the problem is where I have placed my racket code files. I've been putting off moving them and would like to continue putting off moving them. I inadvertently upgraded to Racket v8.0 a couple of days ago. Welcome to Racket v8.0 [cs]. > (current-library-collection-paths) '(#<path:/home/don/.plt-scheme/4.2.1/collects> #<path:/home/don/.racket/8.0/collects> #<path:/usr/share/racket/collects/>) My code files all begin here: /home/don/.plt-scheme/4.2.1/collects/... Racket error message when I run: $ my-prog read-compiled-linklet: version mismatch expected: "8.0" found: "7.8" in: /home/don/.plt-scheme/4.2.1/collects/DG/all/a/b/fn/filename-from-path-and-filename/compiled/filename-from-path-and-filename_ss.zo So, since my compiled file was compiled under Racket version 7.8, there is a mismatch since the Racket now installed is Racket v. 8.0. Thus the reason I'd like to return to running Racket v. 7.8. Thanks for your advice. Don -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
