Problem with installing ROS on Matlab

I'm trying to install a the ROS-Toolbox on Matlab for a Niryo NED 2 robot.

I followed the instructions on the documentation:

https://docs.niryo.com/applications/ned/v1.0.4/en/source/tutorials/setup_ned_matlab_ros_toolbox.html

Tested it with CMake 3.19, Matlab 2022a and Matlab 2023b.

The log file describes a problem with Ninja install but I'm not sure how to fix it.

Do you know the problem eventually?

Here the process on Matlab:

>> folderpath = "C:\Ned2-Pakete\ned_ros"

folderpath =

"C:\Ned2-Pakete\ned_ros"

>> rosgenmsg(folderpath)

Identifying message files in folder 'C:/Ned2-Pakete/ned_ros'..Done.

Running catkin build in folder 'C:/Ned2-Pakete/ned_ros/matlab_msg_gen_ros1/win64'.

Hi Jonas,

It seems there is a redefined variable in niryo_robot_status/msg/RobotStauts.msg - REBOOT_MOTOR has been defined twice.

Unfortunately, this is not supported in ROS Toolbox. In general ROS, the new value would just override the old value. As so, please delete the prior definition (line 10) and try generating message in MATLAB with rosgenmsg(folderpath) again.

Let me know if you face any new issue.

Thanks,

Josh

Hi Josh,

thank you very much!

I also asked the Niryo-Support and they gave the same advice.

I deleted line 21 "int8 REBOOT_MOTOR=13" and it installed correctly.

Greetings
