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
Identifying message files in folder '/home/igs/Desktop/lx/SIM/msg'..Done.

Error building package: build log.
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 Li,
Can you please delete the matlab_msg_gen folder and try once again ?
Thanks,

Hi Jagadeesh,
I tried both using other message and deleting the matlab_gen_msg folder like you mentioned, they both give the same error in the post above.

Hi Xing,
If you have the ROS 2 installation , can you try to build the custom messages outside the MATLAB to figure out whether the issue with MATLAB setup/CMAKE issue or system setup issue ?
We have not seen this issue before. If you have not restarted your machine , Can you give a try once ?
The segmentation fault is usually related to memory. Is your home directory mapped to network drive or local to your machine ?
Thanks,
Jagadeesh K

Hi Jagadeesh,
I have a software package that contains these messages and it can be built successfully, so I would say the system is fine.
Restart machine does not help, same error.
It is a work station, I remotely control the computer via vnc but the drive shall be local.

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
