how to find packages that meta-package contains
As far as I understand, ros is the meta-package that contains several packages, https://github.com/ros/ros/blob/indig... , how do we not that which package does the ros contains?
k-okada@kokada-t430s:/opt/ros/hydro/share$ rospack depends ros
[rospack] Error: no such package ros
k-okada@kokada-t430s:/opt/ros/hydro/share$ rosstack depends ros
[rosstack] Error: no such package ros
k-okada@kokada-t430s:/opt/ros/hydro/share$ rospack depends roslib
catkin
rospack
As a side note: metapackages are only valid dependencies of other metapackages. They are mostly a convenience for users when installing.
