NEWBIE question: Undefined references: How do I find the library that resolves an undefined reference. For example, the output for the gcc linker running in MinGW shows:

C:/boost/boost/asio/detail/impl/winsock_init.ipp:39: Undefined reference to `***@8'

I have googled the documentation a number of ways, but I cannot find the library that will resolve this error. I am sure that this is a common problem. Please point me to the documentation so I can fix this and the undefined references.

Thanks!

That would be the winsock library.

In the future, you can check Microsoft's documentation [1] for info on
their functions. I searched for "WSAStartup", and found [2]. At the
bottom of that page is a "Requirements" box, which tells you the library
it's in.
