Re: [Boost-users] [iostreams] container_device example does not compile?

Hello,

I'm using the container_device example listed here (The full example near the bottom): http://www.boost.org/doc/libs/1_39_0/libs/iostreams/doc/tutorial/container_d...

I modified this class to exist in the global namespace (i.e. not in boost::iostreams::example). It does not compile under MSVC9. I get the following errors. I have NO idea what the compiler is trying to tell me.

Are you prefixing stream_offset with the appropriate namespace? Since you put the class in the global namespace, you would need to do this where the example does not.
