Using class inheritance in roscpp files [closed]

edit

When inheritting from a class you implicitly call its constructor when you instantiante the base class, which mean here : Move_operations_class move_op; You call the constructor (a default constructor since you didn't define it for your class) and since you inherit from moveit::planning_interface::MoveGroupInterface you also call its constructor, you didn't specify any parameters so the program tries to call the constructor with no arguments : moveit::planning_interface::MoveGroupInterface::MoveGroupInterface() as you can see in your error message.

I haven't tried it but specifying the parameters from your class constructor should solve the issue :

class Move_operations_class : public moveit::planning_interface::MoveGroupInterface
{
    public:
        //Your constructor (that should get the string too)
        //And give the string to the MoveGroupInterface constructor
        //Since the constructor of MoveGroupInterface can be called 
        //with a string as parameter :
        Move_operations_class(const std::string &name) : 
            moveit::planning_interface::MoveGroupInterface(name)
        {
            //Do constructor stuff
        }

        //Your other attributes/methods
};

int main(int argc, char** argv)
{
    //init ros
    //Instantiate your object
    //There is a string variable because the constructor wants a reference
    std::string name = "arm_torso";
    Move_operations_class move_op(arm_torso);
    return 0;
}

This should work since from the documentation of MoveGroupInterface you see that there is a constructor accepting only one string (and more parameters but they have defaults values) :

MoveGroupInterface(const std::string& group,
      const std::shared_ptr<tf2_ros::Buffer>& tf_buffer = std::shared_ptr<tf2_ros::Buffer>(),
      const ros::WallDuration& wait_for_servers = ros::WallDuration());
