Hi folks, We have a rather big project which we like to migrate from boost 1.49 to 1.54. I ran into several compile problems under Visual Studio 2010 SP1. The most annoying I was not able to solve yet is the following: We are using boost::serialization a lot and I now get the following error: <snip> error C2995: 'boost_132::shared_ptr<T> boost_132::dynamic_pointer_cast(const boost_132::shared_ptr<U> &)' : function template has already been defined </snip> I checked the sources but I don't understand why this broken with the new version. I removed all references to "shared_ptr_cast" and dynamic_ptr_cast in my code, but compilation still fails. Any ideas? cheers Sebastian
