Along with what Paul explains you can check the library documentation 
page at https://www.boost.org/doc/libs/ for the C++ minimum mode a 
library supports. Library are free to support some of their 
functionality above their C++ minimum and should document the fact if 
they do. Libraries which have no "C++ Standard Minimum Level" field in 
the documentation page have chosen not to officially support a C++ 
minimum level for that library, although this usually means that the 
library supports C++03 and above.
