Is it possible to change the focal length/field of view of the camera used to render the Gazebo GUI? The default focal length looks really short, which has the tragic effect of making my planning scenario look easy to reviewers :( I've noticed there is a camera tag in the world file, but it doesn't seem to be documented anywhere.

I encountered this problem elsewhere, and I think this is due to a bug in pluginlib. In that package's include/class_loader.h, after

#define PLUGINLIB_CLASS_LOADER_H

try adding

#define TIXML_USE_STL

That message definition, along with many others, were moved (in electric) to arm_navigation_msgs, as described here: http://www.ros.org/wiki/arm_navigation. That tutorial hasn't been updated to electric. It may or may not work if you replace that header location along with changing "environment_server_right_arm" to "planning_scene_validity_server". However, you'll also have to use the planning description configuration wizard to build the necessary launch files, and then launch them.

Alternatively, you could use diamondback. You probably shouldn't be including both /opt/ros/diamondback/stacks and /opt/ros/electric/stacks in your ROS_PACKAGE_PATH--you can't generally mix and match packages from different releases.

On Ubuntu, some packages are installable via Ubuntu packages (i.e., apt-get, synaptic), so you could try that first. If no Ubuntu package is available, you can download the source from the repository, put it in a subdirectory of your ROS_PACKAGE_PATH, and compile with with rosmake. That's generally all you need to do.

IIRC, I was getting a similar error compiling rviz on my Mac, and installing Cg seems to have fixed it. I think Ogre may configure itself to not build that library if Cg (or maybe some other dependency) is not present, or something.

My roslib compile works out-of-the-box (diamondback, 10.6, 64-bit). These lines look very suspicious:

/usr/include/AvailabilityMacros.h:108:14: warning: #warning Building for Intel with Mac OS X Deployment Target < 10.4 is invalid.
Linking CXX shared library ../lib/libroslib.dylib

Building for Intel for Mac OS X < 10.4? It looks like your build environment is screwed up. Maybe you have MACOSX_DEPLOYMENT_TARGET set in your environment?
