You don't need to link to any external library to use that function.  Since 
you don't give the actual code that's failing it's hard to be sure what the 
issue is, unless you forgot to either:

1) Prefix the function call with boost::
or
2) Add an appropriate using statement to put the function in the global 
scope?
