I'm debugging a ROS node and I'm trying to find an easy way to change the output level of rosconsole so I can see the debug statements, but I'm not seeing much. I've seen something about changing the log4j configuration file, but this seems obtuse. There are ROS environmental variables for just about everything else - is there nothing for easily changing verbosity?

@gvdhoorn Ha. Sorry, Freudian slip - I meant ROS's cv_bridge. Fixed the original post to reflect that.

Does python cv_bridge perform a copy? The c++ version of cv_bridge has a clear distinction between CvImageConstPtr toCvS

There must be something misconfigured with this system because the same code builds on other systems no problem. Here's the full output. Using Ubuntu 14.04 and the latest ros-indigo packages from the ppa. This is a fresh install on this system. Any ideas what it might be?

Here's the cfg file in question. It starts with a shebang as expected.
