Unit 9 Quiz Error

Hi,

When I submit my quiz for Unit 9, I am getting the error that the package does not compile successfully. However, I have catkin built and ran it just fine. All the names of the files are also correct. Can you please look into this? I have attached the following two screenshots for your reference. Thanks.

This is because you need to compile with catkin_make instead of catkin build

What you can do is delete de /build and /devel folders and compile again

Thanks @roalgoal , that was it. I had gotten by with catkin build up until this unit.
