Hi ros community

Im planing on migrating my packages to catkin. However I have a question regarding the structure of the catkin workspace. Currently I have this setup

/quadrotor [this is my github repro]
  /controllers
    /controller_1
      -CMakeLists.txt
      -manifest.xml
      /src
    /controller_2
      -CMakeLists.txt
      -manifest.xml
      /src
  /experiments
    /user_1
       /what_evernode_1
         -CMakeLists.txt
         -manifest.xml
         /src

So i extensively used folders to structure my ros code. Is there a way i can maintain this hierarchy in catkin? Is it possible to have metapackages of metapackages? then i could easily make for every folder which only holds packages a metapackage.

Thanks a lot for your help

You can have subfolders in your catkin_ws/src folder which are not valid ros packages without any problem. I think you future catkin workspace structure could be like this:

/catkin_ws
 /src
    -CmakeList.txt [symlink by catkin to toplevel cmake]
    /quadrotor [this is my github repro]
      /controllers
        /controller_1
          -CMakeLists.txt
          -package.xml
          /src
        /controller_2
          -CMakeLists.txt
          -package.xml
          /src
      /experiments
        /user_1
           /what_evernode_1
             -CMakeLists.txt
             -package.xml
             /src
  /devel
  /build

You should be able to keep this exact code structure with catkin. The only change will be to the workspace layout. The repository with the source code will exist in a dedicated subdirectory to enable out of source builds.

I think your new hierarchy would be:

new_catkin_ws
   /src
      /quadrotor
      ...

thanks a lot for replying. I was worried every folder needs to be a valid ros packet. I will try and let you know.
