Hello,

Can you please try with catkin build in a clean workspace?. and try installing it's dependency sudo apt install python-catkin-tools to be able to have the catkin build tool.

Thank you,

Hello!

We have tried building it on our end and it works. I recommend you to try in a clean docker to test the same or you can install the binary version that is released in the ROS releases. You can install via command line sudo apt install ros-melodic-aruco-ros.

Thank you,
