Hi Bob, Unfortunatly dot-scheme is currently suffering a bit of bit rot. I was planning on a major revision for PLT 3.0 but I never got around to do it. I did hack a simpler version that worked for PLT 3.0 but only with v1.1 of the CLR. Would that be of any interest? -pp <div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Message: 8 Date: Tue, 18 Apr 2006 12:49:27 -0600 From: "Bob McCormick" <<a href="mailto:mccormick.bob@gmail.com">mccormick.bob@gmail.com</a>> Subject: [plt-scheme] make-extension.ss:6:4: module: identifier         already imported (from a different source) in: string-upcase To: <a href="mailto:plt-scheme@list.cs.brown.edu">plt-scheme@list.cs.brown.edu</a> Message-ID:         <<a href="mailto:5bbec2c0604181149w12be5a74lfebc695e8fff28e2@mail.gmail.com">5bbec2c0604181149w12be5a74lfebc695e8fff28e2@mail.gmail.com </a>> Content-Type: text/plain; charset="iso-8859-1" I've downloaded the dot scheme library (<a href="http://www.rivendell.ws/dot-scheme/">http://www.rivendell.ws/dot-scheme/</a>), and I'm trying to get it to build under the current version of mzscheme (301).   When I run build.ss, I get the following message: "make-extension.ss:6:4: module: identifier already imported (from a different source) at: string-upcase in: (require (lib "make.ss" "make") (lib "process.ss") (lib "13.ss" "srfi"))" Any ideas on how to fix this?  I'm new to plt-scheme, but I'm assuming that there's a variable or function being imported that classes with the the name of another variable or function.  Am I correct?  But I can't figure out from the error message *what* variable or function name is clashing. Any help would be appreciated. Alternatively, I guess I could just install an older version of PLT-Scheme? Thanks! -------------- next part -------------- An HTML attachment was scrubbed...
