It looks to me like the headers you are including are from a different 
Boost version to the library you are linking against - all recent 
Boost.Regex versions mangle the namespace of their functions with the 
Boost version number, but as these missing symbols aren't mangled, I'm 
guessing you're picking up headers from an older version than 1.62.

HTH, John.
