May be I am ignorant, but when i run ctest it fails to create a socket. However when i change it 127.0.0.1, it works

ubuntu 14.0.4

I presume you are referring to

  SocketAddress localhost("::1", 0);

"::1" is the ipv6 loopback address. From my (limited) understanding this means that you don't have an ipv6 address bound to your loopback interface or ipv6 isn't enabled on your box.

You can check by running ifconfig -a and seeing what you have for the lo interface. For example on my machine I have ipv6 enabled and so I see the following for lo:

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:1899 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1899 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1 
          RX bytes:176876 (176.8 KB)  TX bytes:176876 (176.8 KB)

I suspect you will not see inet6 addr: ::1/128 Scope:Host.

You can find out more about ipv6 on the ubuntu wiki article IPv6.
