[Filesystem] v3 using wide url with boost::iostreams::mapped_file

We recently flipped the switch from v2 to v3 of the boost file system. Now that boost:filesystem::wpath is no longer a valid type, how do you work with the wide url and boost:iostreams::mapped_file? With v2 we would void doSomethingWithMapfile(std::wstring& url) { boost::iostreams::basic_mapped_file_paramsboost::filesystem::wpath attribs; // initialize attribs, including attribs.path = url; // create our mapped file boost::iostreams::mapped_file mapFile(attribs); // An then do something with the map file. } Regards, Joe

There is a ticket #4485 which seems to cover this issue https://svn.boost.org/trac/boost/ticket/4485 It looks like someone has proposed a patch to address this, so hopefully it will get applied soon... You could always apply the patch and see if it works for you.

It's not really a patch in the true sense. You need to wrap the path that you pass to mapped_file at the client call site. I've not gotten feedback on how to fix the issue internally to iostreams. Jeff
