Error "unknown address family 10" in roslaunch's ProcessMonitor

Hi all,

I wanted to switch from fuerte to groovy on my virtual machine. After I have successfully compiled all ros_comm packages, I started roscore, but it terminates at startup with the error message:

unknown address family 10

in the roslaunch/

The system is a custom Linux system (compiled with openembedded) and Python 2.7.3. NB: As it a custom Linux system, I did not use rosdep to resolve the system dependencies, but tried to resolve it manually.

Googling for the error above did not give a valuable hint what I am doing wrong.

Does anyone have a clue?

ROS Groovy seems to require python with IPv6 support in constrast to the previous versions (fuerte, electric, ...). After installing python with IPv6 support (--enable-ipv6), the issue was resolved.

Does your Python have IPv6 support? A quick check in iPython with

In [1]: import socket

In [2]: socket.AF_INE
socket.AF_INET   socket.AF_INET6  

In [2]: socket.AF_INET6
Out[2]: 10

implies that address family 10 is IPv6.

This Google Group Posting seems to imply that you may get that error if your Python isn't compiled with IPv6 support, which could be the case given you have a custom embedded Linux install.
