Hello, I have an issue configuring custom message for ROS. There is one specific message that I need : "custom_msgs/Uwb" to do some analysis on a rosbag.
I successfully run the rosgenmsg but when I try add the new classes of message to Matlab I can not find the message in the rosmsg list.
Some details, below :
  • I created a folder /Matlab/custom_msgs/packages/ in which I paste my ROS custom_msgs package (which contains the folder msg with the custom message Uwb, a src folder, a CMakeLists.txt file and package.xml file
  • I execute rosgenmsg('/home/iod/Matlab/custom_msgs/packages/custom_msgs')
  • the building process is going quite well, but a strange mention at the end of the log file " build stopped: interrupted by user." whereas I did not interrupt anything (stdout_stderr.log enclosed)
  • I looked to the related m file, and I find it in the following folder "/home/iod/Matlab/custom_msgs/packages/matlab_msg_gen_ros1/glnxa64/src/custom_msgs/m/+ros/+msggen". This is a strange path.
  • Then I can not add this path "/home/iod/Matlab/custom_msgs/packages/matlab_msg_gen_ros1/glnxa64/src/custom_msgs/m/+ros/+msggen" to the Matlab pat, I tried to use addpath(genpath('/home/iod/Matlab/custom_msgs/packages/matlab_msg_gen_ros1/glnxa64/src/custom_msgs/m'))
  • Finally as I try to find the custom_msgs/Uwb, it is not present.
Someone could help me on this issue ?
Thank you in advance.

ROS Toolbox ships the Noetic with Installation. Multiple versions of ROS may cause this error.
So remving other ROS installation paths from PATH and LD_LIBRARY_PATH resolved the issue.
