We have several Paul's here, but I'll refer to Paul DeLeeuw as Paul until such a time as one of other Pauls enters into the conversation, at which point we may have to resort to another naming convention (apologies to Paul N. Lee) :-) I have uploaded the file compiler error file Paul sent me here: http://www.fractint.org/ftp/experimental/XFract_Errors_5April2002.zip Paul, you can upload files yourself since Damien has created an account for you. If you need help, email me privately. Right off the bat, you need to follow Jonathan's advice and define XFRACT. That will immediately clear up all the near, far, and segname stuff. Of course you will still get some errors, because anything to do with Xwindows won't be appropriate, but you will be way ahead of the game. Tim
