Build error

Hey,

I am getting a building error. upon using catkin_make command.

I am getting this.

Please help!

This error is related to opencv3 shipped now with ROS. A fix has already been release, after a system update, can you confirm if it is working?

[Matthew Edwards]

I'm not that guy, but I've just updated my system packages and I can build process_stereo now.
