signatureHmm, I just compiled it with VC 7.1, it passes gcc 3.3 and borland 5.64 as well. Note, my personal version is 1.32+ so that could explain it It did fail for me (with the same error) with Comeau - same message more or less ? Its a mystery to me. Does test_map pass in your environment? Robert Ramey "Martin Proulx" wrote in message news:41B8C1AB.8030507@okiok.com... Hello, While evaluating the serialization library, I've ran into a problem while modifying my code to add name value pairs to the serialized objects in order to be able to serialize them to an xml file. before doing this, everything worked fine, but now that I'm using NVPs, I get the following error: c:\projects\dev_tools\libs\c++\boost_1_32_0\boost\serialization\access.hpp(1 06): error C2039: 'serialize' : is not a member of 'std::map<_Kty,_Ty>' with [ _Kty=std::string, _Ty=std::string ] I'm using VC 7.1, and a stripped-down but compilable version of the code that causes the problem is included at the end of this mail. I'm really puzzled at this problem as the following modifications to the code will have things compile: -) Comment out only the 'oa << BOOST_SERIALIZATION_NVP(instanceOfB);' line. -) Comment out only the 'ia >> BOOST_SERIALIZATION_NVP(instanceOfB);' line. -) Serializing and unserializing directly the instanceOfA object instead. -) redefining BOOST_SERIALIZATION_NVP to 'BOOST_SERIALIZATION_NVP(x) x' is this really a bug or am I missing something ? Thanks!
