problems when trying to build gazebo_ros2_control

Hi @farbod-new,

there are some packages that are not currently available in rosdep for foxy or rolling. ros2_control is under heavy development, you may need to install these packages from sources.

Thanks for the reply.

As I understand it joint_limits_interface is part of ros2_control (or even ros_control) package and is not an independent package. In other words, how can one install joint_limits_interface from source separately when its source is already included in the ros2_control package?

In the line:
cp -r ros2_control_ddengster/joint_limits_interface ros2_control_ddengster/transmission_interface ros2_control

joint_limits_interface and transmission_interface are copied from another source to ros2_control (ros2_control already includes those folders). While building the package transmission_interface is built with no problem, but joint_limits_interface fails. Why is that?

Thanks,
Farbod

Hi everyone,

I am still having trouble with the joint_limits_interface dependency, although the code is included in the ros2_control package. Do I need a ROS1-Bridge to solve this dependency? Or do I have to compile those dependencies from source with ros2? How do I make this compilation work? Do I need ROS1-Bridge?

Any help is appreciated.

Thanks,
Farbod

I checked the ros2_control repository. It seems that right now joint_limit_interface it's not available https://github.com/ros-controls/ros2_control/tree/master/joint_limits_interface. It has a COLCON_IGNORE inside the folder which means this package will not compile.

I will have a look as soon as possible

Thank you so much!

An extra information that might help is that I successfully built the following repository (with no errors):

Finally, I was able to build "joint_limits_interface". But now, a new error comes up in "default_robot_hw_sim.hpp"

[fatal error: hardware_interface/joint_state_handle.hpp: No such file or directory]

Please see below. Was there any corrections to this file, or the missing ".hpp"?

Thanks,
Farbod

Also, I want to mention that I used the original folder for "ros2_control_transmission_interface" from the original ros2_control repository, rather than "ros2_control_ddengster/transmission_interface" The latter did not build.

But I did use "ros2_control_ddengster/joint_limits_interface" rather than "ros2_control/joint_limits_interface".

I hope this makes sense.

Hi @farbod-new,

Do you manage to build it?

[ahcorde]

Hi @ar0usel ,

Right now, there are some changes that make imposible to compile the code. In particular this issue ros-controls/ros2_control#279. There is some effort trying to revive this code ros-controls/ros2_control#271

I will update the code when this issue is resolved.

Thanks for letting us know. I thought I was doing something wrong.

I have created this new PR #44. This should fix the issues.

Building this package with the Foxy deb packages should be fine.
