I am using the executors in rclcpp, but I keep on getting the following error:

 error: expected primary-expression before ‘exec’ rclcpp::executors::SingleThreadedExecutor exec;

This is exactly the same as in the example for the minimal_composition, so I 'm not sure why it is giving me the error. Does it have to do with these warning?

Mind posting a minimal reproducible example? I don't think there is enough information here to tell what's happening.
