When I make rosdep check costmap_2d i get this error :

 System dependencies have not been satisified:
apt ros-groovy-map-msgs
ERROR[costmap_2d]: Cannot locate rosdep definition for [voxel_grid]
    rosdep key : voxel_grid
    OS name    : ubuntu
    OS version : precise
    Data: <no data>

Howerver, i already have created a package voxel_grid, which had any error. I really don't know what to do I'm using groovy (Ubuntu 12.04)

Hi, did you put voxel grid in pacake.xml and cmakelists ?

Yes I have

Is it same build as you are trying in other question, I mean same package or different. If different please post package.xml and cmakelist

It is the same package but I'm trying to solve two issues : one is that the pcl/conversions.h is not found the second is that the voxel_grid dependencies is not satisfied, that why I posted two question

What do you mean you "created a package voxel_grid"?

Are you executing the rosdep check command in a shell where you have sourced the setup file for groovy (source /opt/ros/groovy/setup.bash)?

Is rosdep cache up to date? (rosdep update)

EDIT: You cannot depend on voxel_grid from a catkin package in groovy, since it is a dry (= rosbuild) package and catkin packages cannot depend on rosbuild packages. In hydro, voxel_grid is a catkin package and this error should not occur.

If you must use groovy and you must depend on voxel_grid, then you should build your package with rosbuild, not catkin. Maybe it is possible to install a catkinized navigation stack (of which voxel_grid is a part) from source ontop of your groovy installtion, but it might not even work at all without major tweaks.

I'm executing rosdep in my workspace /catkin_ws I created a package with catkin_create_pkg Yes I already launched rosdep update

So `voxel_grid` is part of the navigation stack, which on groovy is a `dry` package (i.e. rosbuild, not catkin). That means you cannot build a catkin package that does depend on it. @William: Is this actually the cause of the error, or is something funky going on with the release status of the navig

ation stack on groovy? Should `rosinstall_generator voxel_grid --rosdistro groovy` work or does that only work for stacks with dry packages, @Dirk Thomas? (I noticed `rosinstall_generator navigation --rosdistro groovy` still works).

He said he created a package called `voxel_grid`, could the problem be that there is already a package called `voxel_grid`? http://wiki.ros.org/voxel_grid?distro=groovy

William ( 2014-07-23 14:09:01 -0600 )edit

Unless he has built and sourced the workspace, the package is not going to be picked up. I tested depending on `voxel_grid` from a catkin package and get the same error with rosdep and rosdistro groovy. voxel_grid is dry, so maybe that is expected (although the msg is hardly useful in that case).
