Updating build in ROS msgs for controller_manager_msgs with rosgenmsg fails in Matlab21b

Hi,

I need to update the build in ROS msgs of the package controller_manager_msgs in Matlab21b to the newest version available at https://github.com/ros-controls/ros_control/tree/melodic-devel/controller_manager_msgs since my robot is working with the newer msgs definitions. Main difference can be found in the definition of the ControllerState.msg which uses the HardwareInterfaceResources.msg in the newer version, which is not used in the build in msgs. Unfortunately the build fails with the error found below. Can someone help me on how to fix this? (I tried this on Windows and on a Linux Ubuntu 18.04 computer)

Hi,

the technical support team from Matlab was able to provide a workaround which solved the issue. The workaround is:

"We suggest taking a backup of "controller_manager_msgs" folder under <matlabroot>\toolbox\ros\mlroscpp\custom_messages\share and delete the <matlabroot>\toolbox\ros\mlroscpp\custom_messages\share\controller_manager_msgs folder and try "rosgenmsg" again."

After that, the build was successful and I was able to call the services. The only odd thing is that when doing "rosmsg list", I get every message definition from the controller_manager_msgs package twice. But this does not have any negative effect on the usage of the message definitions.

Hi @Alice,

The error you're encountering during the build process seems to be related to the C++ code generated by MATLAB from the ROS message definitions not matching the expected structure of the ControllerState message, specifically with respect to the hardware_interface and resources fields. This suggests that there might be an issue with how the newer message definitions are being interpreted or with missing dependencies during the code generation process.

Please make sure that all dependencies required by the controller_manager_msgs package are present in your MATLAB environment. This includes the HardwareInterfaceResources.msg and any other new messages or services that the updated ControllerState.msg depends on. Also, verify that MATLAB is looking in the correct directories for the ROS message definitions.

Hi @Debadipto,

thanks for your answer. The HardwareInterfaceResources.msg is in the same folder as the ControllerState.msg as you can see in the attached "controller_manager_msgs" package. Matlab seems to have a problem with the order in which the messages are generated, since it first generates the ControllerState.msg without knowing the HardwareInterfaceResources.msg. Is there any way to tell Matlab to first generate the HardwareInterfaceResources.msg and then the ControllerState.msg?

I tried generating only the HardwareInterfaceResources.msg (which works) and then adding all other message definitions to the package and regenerate it, but the same error occurs....
