Re: [Boost-users] date_time | VC71 | dynamic link

You usually don't need to specify the boost lib, that is done
automatically depending on your project settings.

For dynamic linking you also need to have a .lib file. But this time
the .lib file only contains functions declaration, but no
implementation. Those are in the DLL.

Does that help?
