Hi there, I'm trying to track down a problem I have with building boost and quickbooks. For this I started out with a fresh download of boost 1.45. I also removed user-config.jam and all environment variables which might be used by boost. Such as BOOST_BUILD, BOOST_BUILD_PATH, BOOST_ROOT. Now I open up the command line I get his: ---------------------------------- Setting environment for using Microsoft Visual Studio 2010 x64 tools.
