I am trying to rebuild an existing demo program for Johan Rade's nonfinite facets from François Mauger The program was previously tested with Boost 1.44, gcc 4.4.1, Linux/i686 (32bits) Using MSVC 10, it compiles OK, but fails to link. Can anyone gives me any clues what I am doing wrong? Thanks!

Library directory is I:\boost-trunk\stage\lib;$(LibraryPath) and appears to searching in the right lib file. Runtime library is /MT for release (I have also tried debug with similar results). The following includes are used in the demo program #include <boost/cstdint.hpp> #include <boost/serialization/nvp.hpp> #include <boost/archive/text_oarchive.hpp> #include <boost/archive/text_iarchive.hpp> #include <boost/archive/xml_oarchive.hpp> #include <boost/archive/xml_iarchive.hpp> #include <boost/archive/codecvt_null.hpp> Is there anywhere I should have told serialization/archive not to use exceptions?
