Created attachment 260504 [details] Patch for boost 1.87 compatibility, cpp-files/implementation may be omitted since the port is hdr only Websocketpp 0.8.2 is not compatible with boost 1.87. The FreeBSD-port is done as a headers only, so it's probably fine to only patch the headers. I've included everything I patched to have the github-project work reasonably with boost 1.87. Since the port is done as a headers only the build and install is not broken, but the headers don't actually work. I guess upstream will sooner or later have a fix for boost 1.87 - there is at least a pull request at this time.
