It looks like for some reason boost::filesystem thinks that you are on Windows, not Linux, and thus is using Windows style pathnames (separated by \). Can you post a bit more information about how you are building Boost and how you're including the headers? Are you perhaps building a Windows version of Boost on Linux?
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
