No; assuming you are using boost::noncopyable appropriately, it means the diagnostic mechanism is not detecting that, in this case, your class simply isn't copyable. The warning is useful because, if your class holds dynamically allocated resources, the default copy constructor and copy assignment operator generated by the compiler won't be appropriate. For this kind of classes you must define what "copying" means, to deal with the "shared resource" problem. -- Pedro Lamarão _______________________________________________ help-gplusplus mailing list help-gplusplus@gnu.org http://lists.gnu.org/mailman/listinfo/help-gplusplus
