All, This is probably a bit more of a mac question, but here goes. (Admission: I posted this to ruby-talk as well…) I am trying to use rdoc -d to generate class diagrams on a mac running Tiger (OS X 10.4) for a rails app. I managed to get dot installed, but now am running into problems with dot looking for libraries that either do not exist or are apparently in the wrong place. I probably made things worse by trying (at various times) both Darwin ports and i-installer. Can anyone point me to instructions on getting this working? BTW, the current error I am getting is dyld: Library not loaded: /Local/DarwinPorts/lib/libpng.3.dylib Referenced from: /usr/local/bin/dot Reason: image not found TIA, Keith ---

This would be kinda hackish, but you could download Graphviz[1] and use the prebuilt dot buried inside of the .app package.[2] Or maybe you just need Graphviz. I find quite a bit handier, especially for large graphs. Corey 1.

Guess I am still doing something not quite right, since the output appears to be many diagrams, each of one source file. I am looking for an overall class diagram. Keith ---

How do you tell rdoc to use that one? Keith
