Subject ActiveMQ-C++ compiler warnings
Date Mon, 06 Dec 2010 10:35:47 GMT
I am trying to build my product with the maximum level of g++ compiler 
warnings and with -std=c++0x to check for compatibility with the upcoming 
std. Where I include activemq headers this causes several warnings.

/usr/local/include/activemq-cpp-3.2.3/activemq/core/ActiveMQConnectionFactory.h:33: 
warning: ‘class activemq::core::ActiveMQConnectionFactory’ has 
pointer data members
/usr/local/include/activemq-cpp-3.2.3/activemq/core/ActiveMQConnectionFactory.h:33: 
warning:   but does not override 
‘activemq::core::ActiveMQConnectionFactory(const 
activemq::core::ActiveMQConnectionFactory&)’
/usr/local/include/activemq-cpp-3.2.3/activemq/core/ActiveMQConnectionFactory.h:33:

activemq::core::ActiveMQConnectionFactory&)’

It looks like the pointer member it is worried about is FactorySettings* 
settings.

I am using activemq-cpp version 3.2.3 on ubuntu with GCC version 4.4.3.

Is there any chance of these being fixed please? A clean compile as a user 
of activemq-cpp would be nice....

Andrew Marlow
