Hi,
I am trying to use matlab 2021b linux version to build my ros2 message package. I manage to solve the problems with lib and python but still encounter an error when building the message. Below is the output in command window and the build log is attached in the post.
________________________________________________________________
ros2genmsg msg

Error in ros2genmsg (line 276)
buildPackage(builder, [], ' --merge-install', colconMakeArgs); %other messages might need to be present in the same directory

The problem with this error is that there seems no error in the build log but the build process just cannot be completed. I would suspect it has something to do with CMAKE but I cannot prove it. If you have any idea, please feel free to share, thanks in advance.

Hi Xing,
Could you delete the matlab_msg_gen folder, rerun the ros2genmsg. Please zip the enire "log" folder in matlab_msg_gen/glnxa64 directory and share it with us.
Please also attach the support file generated by the following command:
ros.internal.generateSupportFile
Thanks,
Karthik Reddy
