[Boost-users] operators << and >> on boost serialization

Ok!
I'm starting to freaking out, because I just can't figure it out some
compilation errors when trying to use the boost serialization library.
I just can't manage what I'm doing wrong.
Ok, I think that the best way to translate my problem is to post the
code and the changes I'm trying to do:
So ans as you can see on the attached file:
My project and all of my classes are inside a namespace the FlowEngine.

I have 3 classes: A; B and C to test the boost serialization.

As it is now it compiles and runs good.

But I take the comments of class A to split member serialization, just
doing that I get this errors when compiling:

\3rdparty\include\boost\serialization\access.hpp(93) : error C2662:

And if I just change the operator & with the operators << or >> on the
silv task class I get  this compilation errors:

Anyone???

Pleaaaaseeeee???????????
