Works! with main debian. Had to install the gazebo_ros_pkgs from source once more to make it run. Thank you

2013-07-26 18:07:33 -0600 asked a question Cannot find gazebo_ros plugins after update from 1.9.4 to 1.9.5

I just updated gazebo-prerelease through ubuntu(12.04) update manager from 1.9.4 to 1.9.5 and now gazebo cannot find the gasebo_ros plugins which were working well till now.

Error [Plugin.hh:127] Failed to load plugin cannot open shared object file: No such file or directory
Error [Plugin.hh:127] Failed to load plugin cannot open shared object file: No such file or directory

These were the only plugins I was using for you. I did a search for the plugins and found them in the ros simulator_gazebo stack for some reason. Adding them, to GAZEBO_PLUGIN_PATH doesnt solve the issue either.

ROS: Groovy

Hi, davetcoleman the file was generated after the failed build. I'm not sure what you want me to checkout in git. I've answered below for the changes I made to make the installation work.

Hi EduardoMachiel, here is my CMakeCache.txt - The home/user/catkin_ws/ path will be different in my CmakeCache, make sure those are changed. Let me know what errors you face and I'll try to help as much as I can. Hope we can resolve it by today.

2013-07-12 10:12:24 -0600 commented answer gazebo_ros_pkgs - Erro.

Hi EduardoMaciel, install the gazebo prerelease from here you can use sudo-apt get for that now. I will post my CMakeCache.txt file in a few hours, sorry it is on my lab computer.

HI davetcoleman, found a hint while reading the log of the build for gazebo_ros_pkgs. The make includes /usr/include/gazebo-1.9 and /usr/include/gazebo-1.9/gazebo but only includes /usr/include/sdf-1.4. When I added /usr/include/sdf-1.4/sdf to the CMakeCache.txt in the build directory, catkin_make worked properly and all the nodes are showing up on rostopic. Hope this helps you debug.

2013-07-11 19:36:24 -0600 answered a question gazebo_ros_pkgs - Erro.

Found one solution (not the best way, but it worked for me)
While installing gazebo_ros_pkgs on groovy (any distro that is non-hydro) if an error of the following form comes up during catkin_make :

/usr/include/gazebo-1.9/gazebo/physics/State.hh:26:22: fatal error: sdf/sdf.hh: No such file or directory
Note: the sdf/sdf.hh part may come up more than once.

Let the catkin_make fail, then navigate to


You will find a file CMakeCache.txt open it in any editor and then use search to find all instances of

-I/usr/include/sdf-1.4 and /usr/include/sdf-1.4 in the file.

To these add(do not replace) another command that will include ;/usr/include/sdf-1.4/sdf (note the extra /sdf) so that it should look like

GAZEBO_STATIC_INCLUDE_DIRS:INTERNAL=/usr/include/gazebo-1.9;/usr/include/gazebo-1.9/gazebo;/usr/include/sdf-1.4;/usr/include/sdf-1.4/sdf and


Do this for all instances.

Now go back to ~/catkin_ws and run catkin_make, it should build without errors.

Hi davetcoleman, I installed gazebo and sdf from source and gazebo works well. After that I tried installing the gazebo_ros_pkgs and got these errors - Its entirely different, but seems to be an issue with sdf headers. I looked for the sdf headers and they are installed in the right place. Don't know why this is happening. Thank you for being active!

2013-07-11 15:57:45 -0600 commented question gazebo ros Packages - fatal error: gazebo/sensors/DepthCameraSensor.hh: No such file or directory

Hi m.guedes, where did you make that change? I have the same issue with sdf headers not loading.

I installed gazebo from source using the mercurial clone(after removing the previous one using apt-get remove). And now the error is slightly different while installing gazeborospkgs. The Findgazebo.cmake has worked but FindSDF.cake still remains an issue. Here is the error -

Hi EduardoMaciel , davetcoleman. I cloned the git repos again into my catkinws/src folder and tried running rosdep install as shown in the tutorial with rosdistro as groovy. It gave the same error as before: cannot find rosdep definition for [gazebo]. I went ahead at did a catkinmake but got the following errors: I manually checked for the dependencies using rospack find and all are there. Point to note: Gazebo was installed from debs not source.

That is really good! Thank you davetcoleman, I will try installing the packages tomorrow and let you know how it goes.

2013-07-10 21:31:43 -0600 commented question gazebo ros Packages - fatal error: gazebo/sensors/DepthCameraSensor.hh: No such file or directory

Hi Robert Brockerman, during the catkin_make did you add -DCMAKE_INSTALL_PREFIX=~/some/home/folder? After that what did you add in the PKG_CONFIG_PATH, PATH and LD_LIBRARY_PATH? It would really help if you can post your installation steps as an answer. Thank you!

Hi davtcoleman, I was following the installation tutorial here( and I'm getting the exact same error as posted in the question. Gazebo 1.8.6 was installed from pre-compiled binaries for Ubuntu 12.04 and that is working well. Do I install Gazebo from source and then try?

2013-07-10 15:13:22 -0600 asked a question Writing plugins for gazebo 1.8 and ros groovy


I'm new to gazebo and ros. I would like to model a robot with gazebo that is controlled by ros commands.

So far I have done the following:

  1. Testing gazebo worlds
  2. Adding a pioneer 3at sdf model to the world
  3. Attach a camera and laser sensor to the robot

Now, I would like to write ros enabled plugins for to subscribing to laser sensor data, camera images and publishing to geometry_msgs/twist topics to move the robot in gazebo.

I was following this tutorial to learn how to make the plugins.
On the page it says that "This tutorial may not work with Gazebo Quantal and ROS-Groovy. New documentation is available for ROS integration under the Gazebo 1.8 Tutorials."
There was no link to Gazebo 1.8 tutorials on, and found this page on searching in google.

The first requirement is ROS Hydro, and the links on the tutorial page show that Hydro is still in development. It may release by the end of this month (looking through the ros git repos)
Will the ros-hydro-gazebo-ros packages work in Groovy? If yes, how do I use them?
If not, what is the best way to integrate ros and gazebo?

I tried using simulator_gazebo and that did not work well, so removed everything and started afresh with Groovy and Gazebo-1.8.6.
