I've been working with the ActiveMq-Cpp interface through a dll in windows and I think I've fallen into stl-dll hell.
I was attempting to use: MapMessage.h : virtual std::vector< std::string > getMapNames() const throw( CMSException ) = 0; or Message.h: virtual std::vector<std::string> getPropertyNames() const throw( CMSException ) = 0; I started getting crashes whenever the returned vector fell out of scope. I think this is related to stl and dll's not playing nicely with memory management. If this is the cause of the problem then I see two possible solutions (unless there is a more friendly way to access the map already). 1) Rework the functions MapMessage.h : virtual void getMapNames(std::vector< std::string >&) const throw( CMSException ) = 0; or Message.h: virtual getPropertyNames(std::vector< std::string >&) const throw( CMSException ) = 0; But I've never tested this so I'm not sure if it work properly, or if you still have the same problem. 2) Add accessory functions MapMessage.h : virtual size_t getMapNameCount() const throw( CMSException ) = 0; and MapMessage.h : virtual std::string getMapName(size_t) const throw( CMSException ) = 0; or MapMessage.h : virtual void getMapName(size_t, std::string &) const throw( CMSException ) = 0; I've never taken on this problem before so I have no clue what would work. Any insight would be really appreciated.
