Can anyone inform me of how to download the codings and models from demo? I downloaded the catkin_ws on my computer and what to do next?
I have created a new workspace on my own computer, and replace all 3 folders (build, devel, src) with the same folders from demo. But when I run catkin_make in my workspace, it says:
CMake Error: The current CMakeCache.txt directory /home/hardli/catkin_ws/build/CMakeCache.txt is different than the directory /home/user/catkin_ws/build where CMakeCache.txt was created. This may result in binaries being created in the wrong place. If you are not sure, reedit the CMakeCache.txt
CMake Error: The source “/home/hardli/catkin_ws/src/CMakeLists.txt” does not match the source “/home/user/catkin_ws/src/CMakeLists.txt” used to generate cache. Re-run cmake with a different source directory.
Invoking “cmake” failed
And it is obviously all the paths are different from my own wordspace. So how should I actually use the packages from demo, which I have finished during the course?
