Works for v2. Patches pushed to my bug902 branch on gitorious (discard the last two patches, that just demonstrate the problem). NB I also had to add Release calls for GlobalService and PluginLoader. Please verify the order that I placed things in.
These are the Instance() calls we cover now in RTT v2
shell$ egrep -R "Instance\(\);" rtt | grep hpp | egrep -v "LocalOp|FactoryMap"
rtt/internal/GlobalEngine.hpp: RTT_API static ExecutionEngine* Instance();
rtt/internal/GlobalService.hpp: RTT_API static Service::shared_ptr Instance();
rtt/os/MainThread.hpp: static ThreadInterface* Instance();
rtt/os/StartStopManager.hpp: static StartStopManager* Instance();
rtt/os/TimeService.hpp: static TimeService* Instance();
rtt/plugin/PluginLoader.hpp: static boost::shared_ptr<PluginLoader> Instance();
rtt/types/GlobalsRepository.hpp: static shared_ptr Instance();
rtt/types/Operators.hpp: static shared_ptr Instance();
rtt/types/TypeInfoRepository.hpp: static shared_ptr Instance();
# along with Logger::Instance(...)
I'll take a look at v1 also, which I really need. Is it the same basic process? Any other considerations?
