I am trying to creat a message for ros in maltab.
the .msg filein the folder (/home/bikebot/catkin_ws/src/kinova-ros-master/kinova_msgs/msg) and under the folder there are multiple .msg files.
then I used the funciton rosgenmsg and got followign error.
folderpath ='/home/bikebot/catkin_ws/src/kinova-ros-master/kinova_msgs'
rosgenmsg(folderpath)
Identifying message files in folder '/home/bikebot/catkin_ws/src/kinova-ros-master/kinova_msgs'..Done.
Validating message files in folder '/home/bikebot/catkin_ws/src/kinova-ros-master/kinova_msgs'..Done.
[0/0] Generating MATLAB interfaces for custom message packages... Done.
Error using rosgenmsg (line 332)
No packages with '.msg' files found under
/home/bikebot/catkin_ws/src/kinova-ros-master/kinova_msgs. Each message package directory must
contain a directory named 'msg' that then contains '.msg' files.
Hope someone can help with this.

For up to and including R2020b, ROS Toolbox only supports Visual Studio 2017 for custom message generation on Windows. For R2021a, it also supports Visual Studio 2019. Assuming you are using an earlier release of MATLAB, install VS2017 and use mex -setup to point to it. Or update to R2021a.
