Re: [Boost-Users] Regexp: std::runtime_error, bad pattern?

non dll-interface class 'std::runtime_error' used base for dll-interface class 'boost::pattern'

Good question - Dinkumware don't give std::runtime_error a dll interface, so if you derive from it and try to export/import the result from a dll, then you get that warning. IMO it's a bug in vc7, but Dinkumware may see it differently :-( John Maddock http://ourworld.compuserve.com/homepages/john_maddock/index.htm
