2016-06-08 12:41:37 -0500 answered a question gazebo ros plugin make error: Undefined symbols for architecture x86_64

Maybe the capitalization is the problem: try changing GAZEBO_libraries to GAZEBO_LIBRARIES. Does that help?

2016-03-14 13:57:34 -0500 commented question Gazebo ros control plugin not loading on OSX

gazebo_ros/launch/empty_world.launch has a verbose option. Try adding verbose:=true to your roslaunch invocation

2016-03-14 12:32:36 -0500 commented question Gazebo ros control plugin not loading on OSX

As of gazebo 2.2 (see pull request 925) the .dylib plugin suffix should not be a problem. Is there a way to print more verbose console output to diagnose the error?

2014-09-08 19:35:49 -0500 commented answer rqt --list-plugins is empty even though I have some installed

That tutorial is titled "Create your new rqt plugin", so I didn't read it. I was just trying to use rqt_plot and none of the plugins were showing up.

2014-09-08 16:37:53 -0500 answered a question rqt --list-plugins is empty even though I have some installed

My rqt configuration file in ~/.config/ros.org/rqt_gui.ini was out-dated, possibly because I upgraded my machine to trusty instead of doing a clean install. I deleted the old configuration file, and that fixed the problem.

2014-09-08 16:36:15 -0500 asked a question rqt --list-plugins is empty even though I have some installed

I have installed ros-indigo-rqt-common-plugins, but when I run rqt --list-plugins, it does not show anything. What is the problem?

Note:

I know the answer and am in the process of posting it. I didn't see a good place to add this to the ROS wiki, so I'm posting it here.

2014-04-07 10:58:11 -0500 answered a question gazebo_ros_pkgs build error on saucy/indigo

It looks like an issue a missing dependency for dynamic_reconfigure. I've submitted a pull request to fix it based on advice from @dirk-thomas.

2014-04-07 10:03:17 -0500 commented answer gazebo_ros_pkgs build error on saucy/indigo

I think the nav_msgs is a red herring, building with -j8 mixes up the console output. I just edited the description to try to show the relevant messages.

I'm trying to build gazebo_ros_pkgs on saucy/indigo, and I'm getting the following build error:

Any ideas? I've cross-posted to the gazebo_ros_pkgs issue tracker.

I just had this issue, and I'm not exactly sure what caused it, but I noticed that some of my workspace source folders were on the hydro-devel branch and some on groovy-devel. Make sure you have the correct branches.

2013-09-12 10:36:55 -0500 answered a question Can gazebo_ros actually use bullet?

Gazebo requires bullet version 2.81 or higher. OSRF has libbullet debs hosted at packages.osrfoundation.org for precise and quantal, but not raring. So the gazebo debs don't have bullet support, but if you build from source then you can use bullet with gazebo -e bullet. We're still fixing bugs and adding unit tests for physics, but there is partial support for bullet.

2013-09-12 10:33:28 -0500 answered a question Partial hydro install missing ROS_ROOT variable

After some help from @dirk-thomas, we identified ros-hydro-rosbuild as the provider of ROS_ROOT. So the answer is to make sure you have rosbuild installed if you need the ROS_ROOT variable.

2013-09-12 10:30:55 -0500 asked a question Partial hydro install missing ROS_ROOT variable

I'm using hydro to test drcsim using rosbuild, and I have had instances where the ROS_ROOT environment variable was not set. I did not have a full install of hydro, just a few packages. Not having the ROS_ROOT environment variable can actually break roswtf.

To reproduce, remove all hydro packages, install ros-hydro-roswtf, source the setup script and run roswtf.

$ sudo apt-get remove ros-hydro-*
