Re: [Quantlib-users] Regarding compilations issue

[Luigi B. <lui...@gm...>]

I'm guessing you chose to configure the library with thread-safe observer
and using std::shared_ptr instead of boost::shared_ptr?  In that case,
you'll need to use -std=c++17.  If you use boost::shared_ptr, c++11 is
enough.
