Hi, which branch are you trying to build? master or develop? Also do you have urdf2webots installed separately already? (for instance from pip)

[ad-daniel]

It might have been due to a synchronization issue on our end which has been fixed, could you try again and report back if it solves your issue?

I try again, but I meet the same problem. Failed <<< webots_ros2_driver [10.7s, exited with code 2]

Summary: 5 packages finished [15.0s] 1 package failed: webots_ros2_driver 2 packages had stderr output: webots_ros2_core webots_ros2_driver 7 packages not processed Does this problem have anything to do with the computer system? Because I use mackbook M1.

Does this problem have anything to do with the computer system? Because I use mackbook M1.

Likely yes since webots_ros2_driver relies on libcontroller provided by webots which currently only generates x86_64 libraries, whereas the M1 needs arm64. We are in the process of adding native support of M1 here https://github.com/cyberbotics/webots/pull/4543, which I believe will be supported soon (in a week or two)

Note: native M1 support is only for macOS, not Linux.
