unable to process colcon build on Ubuntu20.04 #32

It seems that a ROS2 error occurs, but I got no idea how to fix that. (cslam) lsh@lsh-Z370-HD3:~/Swarm-SLAM$ colcon build WARNING: Package "libg2o" does not follow the version conventions. It should not contain leading zeros (unless the number is 0). Starting >>> libnabo Starting >>> gtsam Starting >>> libg2o Starting >>> cslam_common_interfaces Finished <<< libnabo [0.24s]

Did you try changing Python versions? https://github.com/carla-simulator/ros-bridge/issues/712#issuecomment-1855047272

Your issue is system specific, it is hard to pin point your problem. I suggest that you use Docker to avoid compatibility problems. I recently made this Dockerfile to help people with that https://github.com/lajoiepy/cslam_experiments/tree/main/docker Good luck!
