I am quite new to programming, however, I decided to install the boost library as it looks very good. The first two lines of my program are: #include ""boost/filesystem/operations.hpp"" #include ""boost/filesystem/fstream.hpp"" Yet when I include the statement: using boost::filesystem; just after, I get an error message saying: ""error C2873: 'boost::filesystem' : symbol cannot be used in a using-declaration"" I am using Microsoft Visual Studio 2005. Where could I have gone wrong? I have tried to find documentation that will help, but I haven't found anything. I have followed the installation to the letter. }}}" Support Requests deleted filesystem None Cosmetic None
