[Boost-users] Newbie problems resolving header paths

I downloaded 1_33_1 and it built and installed. Actually, I'm still not sure what is meant by "install" in the docs. Does something happen than copying a bunch of files to C:\Boost ? VC71 is having trouble resolving paths to the headers. I have: In the project properties, Additional Include Directories: C:\Boost\include\boost-1_33_1; In my .cpp file, I use, for example: #include <boost/date_time/gregorian/gregorian.hpp> I still get: C:\Dev\VS2003\MyProject\Engine.h(3): fatal error C1083: Cannot open include file: 'boost/date_time/gregorian/gregorian.hpp': No such file or directory Hoping I'm overlooking something simple here. Thanks! - JC
