Should be std::ostream, there is no using directive.

The message really was "link error". It appears that there was a mismatch of characteristics like "const" between a function declaration and implementation, which led a misspelled unresolved external. But the message didn't say that.

I attempted to delete the post, and it's deleted on Google groups, but no one else accepts a cancel.

Google just deletes a post from its Usenet client. Usenet is over decade
older than web, Google can't delete anything from it.

That seems unlikely. I'll believe it _started_ link error
