It does also not compile with clang++. Here is the log:

Thanks for this report, I'll have a look this week end. I'll also add the compilation of this example too travis-ci.

[matt-42]

Which version of g++ and clang do you have ? I have no problem compiling the websocket broadcast example (examples/ws_broadcast_server.cc) with g++6.3.1 and clang-3.9.1.

[stkrwork]

i used the example on your documentation website. I already found the error, there is a difference at rcclient. the parameters passed on to it in the code on the docu site is different than in the code in the examples/ folder.

This is the example I used that time:
http://siliconframework.org/docs/websocketpp.html

[matt-42]

I'll replace the code of this page by a link to the real example.
