Hi, Changed the version in 2005 vcproject file (vs2005-activemq.vcproj) to 7.10 and tried to compile it with VS2003. Got errors that looked like (not posting all, just a few to keep the post readable) ----------------------------------------------------------------------------------------------------- ----------------------------------------------------------------------------------------------------- ..\src\main\activemq\connector\ConnectorException.h(80) : error C2511: 'decaf::lang::Throwable *activemq::connector::ConnectorException::clone(void)' : overloaded member function not found in 'activemq::connector::ConnectorException' ..\src\main\activemq\connector\ConnectorException.h(29) : see declaration of 'activemq::connector::ConnectorException' ..\src\main\activemq\connector\ConnectorException.h(80) : error C2511: 'activemq::exceptions::ActiveMQException *activemq::connector::ConnectorException::clone(void)' : overloaded member function not found in 'activemq::connector::ConnectorException' ..\src\main\activemq\connector\ConnectorException.h(29) : see declaration of 'activemq::connector::ConnectorException' ----------------------------------------------------------------------------------------------------- -----------------------------------------------------------------------------------------------------
VS2005 compiler doesn't complain about this but VS2003 compiler does. Investigated a bit to find out that the return type of virtual function clone() is different in the inherited classes. For e.g: ---------------------------------------------------------------------------------------------------- for ConnectorException : public exceptions::ActiveMQException virtual ConnectorException* clone() const{ return new ConnectorException( *this ); } ---------------------------------------------------------------------------------------------------- Return type above is ConnectorException* but the base class has following definition: ---------------------------------------------------------------------------------------------------- virtual ActiveMQException* clone() const; ---------------------------------------------------------------------------------------------------- Return type above is ActiveMQException* I feel this is not right. Cloning should return the base type. Moreover VS2003 compiler is pretty unhappy about it. Please let me know what you guys think about this. Meanwhile I have changed it in my activemq-cpp distribution to cheer up the compiler.
