Does linker recognise namespace alias?

I'm compiling a program on Windows using vs2008, I get a linker error LNK2019, my object file has a unresolved symbol 

func(boost::shared_ptr<Type> x)

The library A I'm linking is supposed to define this symbol, but dumpbin shows the symbol defined is

func(boost_1_53_0::shared_ptr<Type> x)

I think the boost library is using bcp to make boost a alias of boost_1_53_0, but does the linker know about namespace alias?

If not, where does this build go wrong?

I think the answer is: no, the linker doesn't care about namespace alias, all symbols should be unified, the problem here is library A was not build correctly with boost 1.53.

no, this is not the problem. Could we see your code? probably you need to include the header. It look like forwarding, but shared_ptr is a template class. so forwarding is not a good idea
