set_option: Bad file descriptor / GuestWorkerClientProtocol.connectionLost

[IvanK]

Hi all,

I'm trying to get crossbar.io started and following the instruction from here:
https://github.com/crossbario/crossbar/wiki/Getting-started-with-Cplusplus

Unfortunately, crossbar won't start. Do you happen to know what the problem might be?

Thanks.
Ivan.

ivan@ivan-VirtualBox:~/hello$ crossbar version

Crossbar.io software versions:

Crossbar.io     : 0.9.8-3
Autobahn        : 0.9.1
Twisted         : 14.0.2-EPollReactor
Python          : 2.7.6
UTF8 Validator  : autobahn
XOR Masker      : autobahn

hello:python template works, but not hello:cpp

[IvanK]

Moving forward:

an asio::tcp::socket ctor taking one-parameter does not open a socket, see 
http://www.boost.org/doc/libs/1_56_0/doc/html/boost_asio/reference/basic_stream_socket/basic_stream_socket.html

So instead of 

tcp::socket socket(io);

in hello.cpp

there should rather be

tcp::socket socket(io, boost::asio::ip::tcp::v4());

[IvanK]

And finally,

hello.cpp registeres 'com.example.add2' function whereas JS calls "com.myapp.add2".

Hi Ivan,

sorry for the long delay .. I am still catching up with my mail backlog.
This (and the previous issues you mention) are now fixed in Crossbar.
0.9.9. Further, AutobahnCpp has gotten some improvements as well.

Cheers,
/Tobias
