Hi, Im new to boost and after building the libraries to c:\boost, I wanted to go through the [String Algorithm First Example]. Im using visual c++ 2005 with windows xp SP2 and when I tried to build my project I get the following error: fatal error C1083: Datei (Include) kann nicht geöffnet werden: "boost/algorithm/string.hpp" corrosponding to that line of code: #include <boost/algorithm/string.hpp> All # include calls have a unix like path description and not a common windows path like : c:\boost\include\algorith\string.hpp. That seems to be a general problem with all #include calls in all boost *.hpp files. I have included the the path[c:\boost] and [c:\boost\include] to my VC++ INCLUDE Path. Can somebody please help. -Frank
