While running cl for msvc 8.0, following the tutorial directions for the example.cpp I get an error " can't find file utility - which is the include file in example. I notice that the path returned in the error has the slashes reversed after the BOOST_ROOT dir. The file definitely exits so I thought it must be a pathing type error. Anyone see this before ? Sorry, I am new to this program/list. I am trying to right some wrappers for C++ to be used by Python.
