error: ‘async_connect’ is not a member of ‘boost::asio’

Was working through your example but get continuously stuck compiling your sample applications.

Have tried this on both OSX 10.7 and Ubuntu 12 with Boost installed via brew and apt respectively.

Is this something wrong with my setup or have I missed a stage?

async_connect was added in Boost 1.47. You will need a copy of boost later than this to use client functionality in WebSocket++. For Ubuntu 12.04/10 two versions of boost are available via apt, 1.46 and 1.48. Use package name libboost1.48-all-dev to get the 1.48 version.

I am not as familiar with homebrew and don't know how to check exactly what version it installs. I've always compiled my own copy of boost on OS X. Anything at or above 1.47 should work though. Server roles may work with older versions still, though keep in mind some major improvements were made to the TLS/SSL systems in 1.47 that you'll likely want to have.

Brilliant. Thought I was going nuts.

The Ubuntu version I'm using is pretty out of date too. Will build from source. Thanks, great library too :)
