Thanks for your response, Igor. If nothing else, I'm glad to hear I'm not the only one dealing with this.
I'm now trying to move the necessary Boost source into my project and build it directly instead of linking to a lib. I need ASIO and System. The error of the moment is "system_error' is not a member of 'boost::system".
If anyone has hints about compiling (non-header-only) parts of Boost directly in a project, I'd appreciate hearing them.
