Thanks for your reply.

I'm using boost 1.33.1.

I only compiled serialization library.The lib I use is libboost_serialization-vc71-s-1_33_1.lib.I only can use this library when using other library,like dynamic library or multi-thread library,even normal object cannot be serialized.

If you like,I can send the library I compiled to you.
