Hello Arkadiy, I could solve the problem with gcc-4.1.2. In file expression_registry.hpp the tags struct key_index_tag; struct iterator_index_tag; struct cache_tag; struct cover_tag; Are forward declared. The class expression_registry_traverse_functor uses this tags as type switches for the function operator template<class R> void operator()(R& r, key_index_tag tag) const; template<class R> void operator()(R& r, iterator_index_tag tag) const; template<class R> void operator()(R& r, cache_tag tag) const; template<class R> void operator()(R& r, cover_tag tag) const; Because the tags are forward declared the compiler doen't know the complete type. I change your implemention with passing the tags as const&. Then the gcc-4.1.2 accepts now the code. template<class R> void operator()(R& r, key_index_tag const& tag) const; template<class R> void operator()(R& r, iterator_index_tag const& tag) const; template<class R> void operator()(R& r, cache_tag const& tag) const; template<class R> void operator()(R& r, cover_tag const&) const; With regards, Oliver

I saw RTL from Dmitriy Arapov and Arkadiy Vertleyb in teh Vault but it seams not to reviewed yet?!
We never submitted it for review.
If I try to compile the example (EarthCoord) I get following errors:
I'll take alook at this.
Regards, Arkadiy
