Hello everyone, I'm trying to write some c++ code that uses the Costmap2DROS class, but I have this error at compile time:

error: no matching function for call to ‘costmap_2d::Costmap2DROS::Costmap2DROS(std::__cxx11::string&, tf2_ros::Buffer&)

/opt/ros/kinetic/include/costmap_2d/costmap_2d_ros.h:80:3: note: candidate: costmap_2d::Costmap2DROS::Costmap2DROS(std::__cxx11::string, tf::TransformListener&)
   Costmap2DROS(std::string name, tf::TransformListener& tf);

The line that gives the problem is this one:

costmap = new costmap_2d::Costmap2DROS("global_planner", tfl);

where tfl is a tf2::Buffer& object.

I have seen from these reference pages
http://docs.ros.org/jade/api/costmap_...

http://docs.ros.org/melodic/api/costm... that depending on the ROS version you have different constructors for the class. The problem is that I am working on ROS Kinetic, that according to the ROS wiki, uses the melodic version, so why my compiler is using the jade one? How can I solve this?

Thank you in advance to anyone who can help

According to the docs, in ROS kinetic the constructor for the Costmap is the following

Costmap2DROS (std::string name, tf::TransformListener &tf)

From your error message your ros distro is kinetic, not jade or melodic, so you should go with this one (which in this particular case it's equal to the jade one).

Thank you. My bad, I misread the references
