Rene, Sorry to be stupid here, but after rereading the things you suggested, I still don't know the answer to either of my questions. For question 1), are you saying that if I want to stream a string stored in a class as an old C style char * pointer, I would have to write a specific streamer for that class that knew how to write out an object (presumably by doing a strlen(), streaming the count, and then streaming the bytes)? For question 2), I am not sure how the ios references in the Dict.cxx file (it has code that does G__search_typename2("ios& (*)(ios&) ") ultimately get resolved. Is there a file or library I need to include? I am including all the libraries that are used in building make Event. -----Original Message----- From: Rene Brun [mailto:brun@pcbrun.cern.ch] Sent: Tuesday, September 24, 2002 10:39 AM To: Salkind, Lou Cc: 'roottalk@pcroot.cern.ch' Subject: Re: [ROOT] A couple of root dictionary questions Hi Lou, Please read chapter about Streaming at page 201 of the Users Guide. Read section "Dynamic Arrays" See a concrete example at $ROOTSYS/test/Event.h,cxx, MainEvent.cxx. To build this example, run gmake Event You do not need to include <iostream.h> on Linux. Should be <iostream> by the way.
