Hi,
These are catkin issues and unfortunately I cannot really help you with this. What you can try is to clone the repo again and use command catkin_make instead of catkin_make_isolated.

ive done the catkin_make too and seems to have the same error. do i need to create new workspace and clone into it?

You should not do catkin_make after catkin_make_isolated and vice versa. Delete the cloned repo, clone a new one and try the other method. That is the only thing I can suggest.

i think it is a problem caused by the velodyne_simulator don't support gazebo11 it just support until gazebo9
