Compile error with cob_gazebo_ros_control

Fan-loewe commented 4 years ago

Hello,

I am using Ubuntu 18.04 and ROS melodic. I downloaded the cob_gazebo_ros_control package from branch: kinetic_release_candidate. When I compile it in my work space with catkin_make, it shows following errors.

does anyone have the similar problem? Thanks a lot.

@Fan-loewe I've just restarted our travis jobs: https://travis-ci.com/github/ipa320/cob_gazebo_plugins/builds/160334464 and they pass for both kinetic and melodic

kinetic_release_candidate should also be the version you get when installing it - cob_gazebo_ros_control is released to melodic - you can just install it via sudo apt install ros-melodic-cob-gazebo-ros-control

other than that, I don't know why you cannot compile it on your machine do you have any special branch or source overlay for https://github.com/ros-controls/ros_control or https://github.com/ros-simulation/gazebo_ros_pkgs?

@fmessmer thank you very much for your quick reply.

Exactly as you said, I have a ros_control package in my working space. After I removed that package, cob_gazebo_ros_control could be compiled. So it means cob_gazebo_ros_control will get conflict with other controllers?

what version of ros_control are you using? can you post the hash/branch here? it might point us to an upcoming API-break...

@fmessmer I suppose the ros_control package is my problem. Before I was using Ubuntu 14.04 Indigo, I downloaded ros_control from the indigo branch, it worked fine at that time.

Since I need a more updated Ubuntu version 18.04 and ros melodic, I copied the packages I used before and make it in the new environment. The ros_control package didn't show any error when I make it but it seems have some potential problems.

I would appreciate it if you can help me with another issue on cob_control_mode_adapter. I downloaded the package from here: https://github.com/ipa320/cob_control/tree/melodic_release_candidate when I launch a node including this node, it shows the following error:

but I have this package in my catkin_ws. Do you have any idea what the problem is? Is there anything in the CMakelist I need to change?

first, you cannot just copy SW which was working in indigo to a melodic machine and assume it is still working likely there have been (API-breaking) changes from during jade, kinetic, lunar, melodic distro
if you relied on a feature that you implemented for indigo, you'll have to migrate/rebase it to the latest version for melodic
if you dont have any custom changes simply try using the released version of the needed packages - no need for source overlays
you issue with cob_control_mode_adapter is not related to cob_gazebo_plugins repo (likely the package is not in your CMAKE_PREFIX_PATH or ROS_PACKAGE_PATH - i.e. your workspace is not set up correctly)

closing this issue as it is not a problem with this repo but due to wrong workspace layout of @Fan-loewe
