Are there any special compiler flags that I need to use to build a C++ project using boost with Visual Studio 2005? I am getting a C2220 compiler error that an object cannot be created: 1>------ Build started: Project: data_containers, Configuration: Debug Win32 ------ 1>Compiling... 1>Memory_Map.cpp 1>C:\Program Files\boost\boost_1_33_1\boost/format/group.hpp(124) : error C2220: warning treated as error -
