How to compile a C++03 project that uses a C++11 library API?

I am required to use a shared library A and its API which was compiled using C++11. It uses C++11 features like std::mutex and std::shared_ptr in its API. I have no control over library A.

However, I am also being required to compile my code using C++03 which uses library A's API.

I am pretty sure that this cannot be done because I get compiler errors stating that the uses of std::mutex, std::shared_ptr, and others in the API are not found. (My understand is, if library A didn't use C++11 specific types then I should be able to do this.)

But I just want to make sure that there isn't something I am not understanding that I need to do in order to compile my code against the C++11 library A.

So the question is, can I compile my code using C++03 against a shared library and its API that uses C++11?
