How to solve it？

Hi, I need a bit more information in order to help you. What operating system are you on? Are you able to compile the docker image and ROS package without errors using make build-docker build-pkg? What debugging steps have you tried already?

I recommend you take a look at dmce_tests/CMakeLists.txt. Some further reading on rostest:

Hello, I am using Windows, and I am operating under Ubuntu 20.04 in VMware. I can compile the docker image using make build-docker, but make build-pkg will report an error: I checked the Makefile and couldn't find the problem

Because I am a beginner, the debugging is limited. I will take a look at the information you provided. Thank you for your reply！

Some additional tips:

• If you're unfamiliar with Docker, I recommend reading a bit about it. Particularly docker volumes. Docker is not strictly required to run this project but it allows you to run it without installing ROS locally.
• Catkin is the build system used by ROS. Again I recommend getting familiari with it first and perhaps making a test project of your own before trying to run this one which is fairly complex. Online tutorials.
• make sure the GIT and CATKIN_WS variables in the project's Makefile are set to the appropriate directories in your Ubuntu VM, and that they exist.
• make bash will open an interactive bash session in the Docker container, which can help with debugging.
