   Boost Multi_Index Help
  Hi guys,I'm having a big problem setting up a texture manager that is going to track textures by unique texture filename and name. What I want is to be able to add textures by passing a filename and a name for the texture, and the texture manager adds it to the list. I can do it with the std::map, but I want to try to do it with boost::multi_index since it has in-built ability to sort and retrieve items. So, how would I do that? I tried declaring a class like this:[SOURCE]class ION_ENGINE_EXPORT CTextureManager : public CSingleton<CTextureManager>, public boost::multi_index::multi_index_container<ITexture,boost::multi_index::indexed_by<boost::multi_index::sequenced<>,boost::multi_index::ordered_unique<std::string> >>{//};[/SOURCE]But it complains with heaps of strange and weird errors that I cant translate yet. Can anyone proficient with Boost give me an example or at least a pointer to what I should be doing to have a decent working texture manager?Thank you.
