It sounds a bit like the initial connection is not working. Unless you are using a connection proxy, you do have to disconnect from the console (where you were running kdb) in order to successfully connect gdb. Generally speaking you would not need kgdb if you can make use of the virtualbox debugger backend, but in this case I'll assume you have some reason you want to use this particular configuration. :-) Cheers, Jason. _______________________________________________ kdb mailing list [email protected] http://oss.sgi.com/mailman/listinfo/kdb
