### Service Server refuses to advertise my service/function?

Hello I'm writing a server whose job is to offer a 6DOF pose estimation, but I'm having problems advertising it as it seems that I'm giving it a function with too manny argument, even tough I'm following the tutorial very closely.

This is the relevant part from the node's main:

 ros::init(argc, argv, "epsilon");
ros::NodeHandle nh("~");
PoseServer server;
ros::spin();
return 0;


And this is how I implemented compute_Pose within the PoseServer class:

bool PoseServer::compute_Pose(epsilon::Pose::Request &req,
epsilon::Pose::Response &res)
{
//Here I calculate the pose and store it as a string for now
res.pozitie = pose_string;
}


And this is the Pose.srv as I've named my .srv file and the package's working name is epsilon, it's not really supposed to work with string but I wanted to start with something simple and try to advertise it first:

string A
---
string pozitie


The error I got is:

no matching function for call to ‘ros::NodeHandle::advertiseService(const char [18], <unresolved overloaded function type>)’
note: candidates are:
/opt/ros/electric/stacks/ros_comm/clients/cpp/roscpp/include/ros/node_handle.h:821:17: note: template<class T, class MReq, class MRes> ros::ServiceServer ros::NodeHandle::advertiseService(const string&, bool (T::*)(MReq&, MRes&), T*)
//And a whole list of other candidate templates
/ros/node_handle.h:1111:17: note:   candidate expects 1 argument, 2 provided


I think it's telling that I have to add something more than req and res or maybe to declare them in another fashion but I don't see exactly how.
