According to this tutorial,it says:"There can be no more than one package in each folder. This means no nested packages nor multiple packages sharing the same directory."But next to this, a catkin-work space can have many packages,how can it be explained?
According to the official doc: http://wiki.ros.org/ROS/Tutorials/Cre...
you can have in your workspace several packages(package means here a ROS project with one or more executable applications)
what you are not allowed to do is: putting package1 and package2 in the same folder
sorry to response so late to you.But actually,package1 and package2 are in the same folderworkspace_folder/src/.Sorry to bother you.
see the image and realize that packages inside workspace_folder/src/ are ok ALWAYS, but you CAN NOT put inside package_1 another 2 packages.....
In your catkin_workspace you can have multiple packages. What it says that in one of those packages if you want to have more than one package it is basically called a meta packages. However each metapackage can contain be a package itself. You can't make a metapackage of a metapackage.
So inside your catkin_workspace
Package 2
Package 3
Thanks for your answer, I love this Q&A community.Learning ROS is a little hard for me.Hope I can get clear about my questions during learning.
No problem, the community is for co-existing and learning from each other.
