[boost] [serialization]: 1.32/VC7.1:error C2039: 'serialize' : is not a member of 'std::vector<_Ty>'

Hi Robert I got the following error from the serialization access.cpp: : Schema.cpp c:\boost\boost\serialization\access.hpp(106) : error C2039: 'serialize' : is not a member of 'std::vector<_Ty>' with [ _Ty=GLOB::SUB::Key ] ... ... For sure, I have doubled checked that the "boost/serialization/vector.hpp" file is well included at the very beginning of Schema.cpp This error appears only with binary archive. With an XML archive, the source Schema.cpp does not produce any error. I am not able to reproduce it on a small case. Is there anyway to trace/or activate an helper that could show up be the underlying problem?? Regards Francis ANDRE
