Hi all, I'm currently working on a large software project having an unchangeable dependency on boost 1.33, but I would like to use functionality from a more up-to-date version of the library (say 1.54). Can it be done? If so, how ? One of the things we aim to achieve is use the std::hash and unoredered_map from boost 1.54, while also using othe containers from boost 1.33. Since boost if mostly header only and template-based, using an intermediary interface doesn't work well. Any ideas ? Are we better off using another library instead of boost to avoid conflicts ? Help appreciated, thanks. Kind regards, Wilfried K. ----- Cordialement, Wilfried Kirschenmann "Ma femme, si elle croit que je vis, croit que je marche. Les camarades croient que je marche.
