I just tried our infamous WSocketNotifier with boost 1.34.1 and wt
2.2.4. This indeed seems to be broken. Boost asio's mechanism for
doing this changed in boost 1.36, and
It does work with later boost versions (I just tried wt 2.2.4 with
boost 1.36 and 1.37). I would therefore recommend 1.36 or later. :-)
See below a small (very silly) example that I use. It can only handle
a single session, and requires you to connect to port 7000 using
telnet after you started a session.
