Hi, gvdhoorn, i have encountered the same problem here, i have tried many methods but no use, could you help me? thank you very much

I have encountered same problem like this, the detail are in here, and i have tried many methods but no use, could you help me solve it?

I have tried this command but the output is same with the previous

aicrobo@ubuntu:~/catkin_ws$ rosrun message_to_tf message_to_tf
[rosrun] Couldn't find executable named message_to_tf below /home/aicrobo/catkin_ws/src/message_to_tf

I have encountered the same problem, but i don't know what check out the source into my catkin workspace and build it exactly means, could you give me the detailed instructions? Thank you very much. And my question is at here

I have installed that package in home/aicrobo/catkin_ws/src, and catkin_ws is my workspace.

aicrobo@ubuntu:~/catkin_ws$ rospack find message_to_tf
/home/aicrobo/catkin_ws/src/message_to_tf

I run the command :sudo apt-get install ros-indigo-rqt-common-plugin,but the answer is: E: Unable to locate package ros-indigo-rqt-common-plugin. I don't know why ,anybody who knows please tell me how to solve it. thank you very much.

I'm new in ros, after downloading the hector_quadrotor package, many Cmake error occurred while catkin_make, it's about target_link_libraries, but i don't know how to solve it.

For example, Cmake error like this:

CMake Error at hector_quadrotor/hector_quadrotor_gazebo_plugins/CMakeLists.txt:63 (target_link_libraries):
  Attempt to add link library "/usr/lib/x86_64-linux-gnu/libpthread.so" to
  target "hector_gazebo_quadrotor_simple_controller" which is not built in
  this directory.

CMake Error at hector_quadrotor/hector_quadrotor_gazebo_plugins/CMakeLists.txt:63 (target_link_libraries):
  Attempt to add link library
  "/usr/lib/x86_64-linux-gnu/libconsole_bridge.so" to target
  "hector_gazebo_quadrotor_simple_controller" which is not built in this
  directory.

and the related information in CMakeLists.txt like this:

    add_library(hector_gazebo_ros_baro src/gazebo_ros_baro.cpp)
    target_link_libraries(hector_gazebo_ros_baro ${GAZEBO_LIBRARIES} ${catkin_LIBRARIES})
    add_dependencies(hector_gazebo_ros_baro hector_uav_msgs_generate_messages_cpp)

    add_library(hector_gazebo_quadrotor_simple_controller src/gazebo_quadrotor_simple_controller.cpp)
    target_link_libraries(hector_gazebo_quadrotor_simple_controller ${GAZEBO_LIBRARIES} ${catkin_LIBRARIES})

  if(hector_quadrotor_propulsion_LIBRARY)
      add_library(hector_gazebo_quadrotor_propulsion src/gazebo_quadrotor_propulsion.cpp)
      target_link_libraries(hector_gazebo_quadrotor_propulsion ${GAZEBO_LIBRARIES} ${catkin_LIBRARIES} ${hector_quadrotor_propulsion_LIBRARY})
      add_dependencies(hector_gazebo_quadrotor_propulsion hector_uav_msgs_generate_messages_cpp)
    else()
      message(WARNING "Quadrotor propulsion model is not available. Skipping target hector_gazebo_quadrotor_propulsion...")
    endif()

    if(hector_quadrotor_aerodynamics_LIBRARY)
      add_library(hector_gazebo_quadrotor_aerodynamics src/gazebo_quadrotor_aerodynamics.cpp)
      target_link_libraries(hector_gazebo_quadrotor_aerodynamics ${GAZEBO_LIBRARIES} ${catkin_LIBRARIES} ${hector_quadrotor_aerodynamics_LIBRARY})
    else()
      message(WARNING "Quadrotor aerodynamics model is not available. Skipping target hector_gazebo_quadrotor_aerodynamics...")
    endif()

and the line 63 in CMakeLists.txt is :

target_link_libraries(hector_gazebo_quadrotor_simple_controller ${GAZEBO_LIBRARIES} ${catkin_LIBRARIES})

wish for your help! thanks very much!

I'm sure that my path is correct. But when I run another urfd file"01-myfirst.urdf", which is in the same package with "my_robot.urdf", it succeeded.

xu@xu-ThinkPad-SL410:~/catkin_ws/src/urdf_tutorial/urdf$ check_urdf 01-myfirst.urdf robot name is: myfirst Successfully Parsed XML

Do you mean running check_urdf /home/xu/catkin_ws/src/Learning_tutorials/urdf/my_robot.urdf directly to parse my file? I have tried that way ,but still failed.

I followed this answer but the same question still appeared.

 xu@xu-ThinkPad-SL410:~$ cd   ~/catkin_ws/src/Learning_tutorials/urdf
        xu@xu-ThinkPad-SL410:~/catkin_ws/src/Learning_tutorials/urdf$ check_urdf my_robot.urdf
Error:   Error document empty.
         at line 72 in /build/buildd/urdfdom-0.2.10+dfsg/urdf_parser/src/model.cpp
ERROR: Model Parsing the xml failed

I followed the urdf /Tutorials/ Create your own urdf file: http://wiki.ros.org/urdf/Tutorials/Cr... , and run check_urdf my_robot.urdf, but the answer is:

Error:   Error document empty.

at line 72 in /build/buildd/urdfdom-0.2.10+dfsg/urdf_parser/src/model.cpp

ERROR: Model Parsing the xml failed

and I can't find the file of build/buildd/urdfdom-0.2.10+dfsg/urdf_parser/src/model.cpp, I don't know how to solve it, anyone could help me ?

i'm a newer to gazebo. I followed installation tutorial in http://gazebosim.org to install gazebo, but when i run 'gazebo', there is no response. And when i run 'gzserver', no response , too. then, I run 'gzclient', the gazebo GUI appeared. But the area of world view is black,I can't see anything in this area. How can i solve it?

hahaha, i got it.Maybe i misunderstood it before, thank you for your explanation.

I followed the Tutorials and built a talker.cpp and listener.cpp

http://wiki.ros.org/cn/ROS/Tutorials/...

but when i run the command:$ rosrun beginner_tutorials talker, the output likes that:
