    If you're looking for a simple websocket lib with minimal dependencies, https://github.com/machinezone/IXWebSocket might be a good choice. It doesn't need Boost or ASIO (most other websocket libs do), TLS and ZLIB are optional.
  • Linker errors in a new project when including a library

    My apologies in advanced - I'm very new to CPP and this is a pretty specific issue, but this GitHub issue explains the problem I'm having. I don't think that matters much though, I found a different issue that supposedly is the fix, except I have no idea how to use it.

    When I try building the project using the main example the library provides, it gives me these errors (image). Here is main.cpp from the repo. The developer responded to someone else having the same issue with the code I quoted in my post, but like I said, I have no idea what to do with it. If I can figure out where to put it and get main.cpp working, I can go from there.
