I have a problem where a successfully built Unity game won't run on Ubuntu 18.04 LTS. The problem seems to be connected to the linker, which can't be found. The app crashes after the splash screen. An excerpt from the Player.log file: I do have libdl.so installed. Here is the output of ldd on the game executable: I also checked the symbolic link to libdl.so.2, which is valid and points to libdl-2.27.so. I am using UnityRos2, which adds several client libraries for ROS2 as plugins. Here is the repo, including a sample Unity project: https://github.com/DynoRobotics/UnityRos2 I have no problems running the application in the editor. There are also no build errors. I have tested this with Unity 2019.2.14f1 running on Ubuntu 18.04 LTS.
