I want to use nav_msg/GridCells.msg and OccupancyGrid in my package,How to use it in the source code. It is not a member of nav_msgs and it is only a .msg and I am unable find documentation for using GridCells as a member variable i.e. I want to initialize occupancy grid and add data to it and publish it as a topic. I want to do in cpp.
What have you tried so far? What isn't working?
The c++ publisher/subscriber tutorial shows how to create a ros message, add data to it, and then publish it.
I just initialized as : nav_msgs::OccupancyGrid og; og.data=temp_data; but the error while compiling is OccupancyGrid is not a member of nav_msgs Is this how you initialize? Is OccupancyGrid not a member and cant it be used like a class?
Sounds like you might forgot to put a #include <nav_msgs occupancygrid.h=""> into your source file. Still, lindzey´s comment applies: Post code, then people can make informed comments.
It was a simple mistake, OccupancyGrid was typed as OccupacyGrid. Thanks for your help. :)
