The program should now compile !?
Saddly, the problem persists. Perhaps it is something other than the library. Here are some code snippets in case there are issues there.
Included in the serialization library is a directory VC7IDE In tihs directory there is a solution as well as projects for demos and tests. in a new solution. add the project demo. this is the simplest demo and includes one file. a) Select Debug runtime-dynamic as the project confguration b) Check the properties. c) Try to build as is. Most likely this will fail for inability to find the serialization library. d) Tweak the properties to link to your recently built libboost_serialization.lib. e) Try to build again f) if you get linker errrors, try tweaking the properties - especially the C++ code model - multi-threading DLL Debug. Let me know what happens. Robert Ramey
