Header:
#include <unordered_map>
#include "O.h"
#include "P.h"
using namespace std;
class O{
public:
O();
unordered_map<int,P>* X();
unordered_map<int,P>* Y();
private:
unordered_map<int,P>* b;

source:
#include "O.h"
#include "P.h"
#include <unordered_map>
using namespace std;
O::O(){
a= new unordered_map<int,P>();
b= new unordered_map<int,P>();
}
unordered_map<int,P>* O::X(){
return b;
}
unordered_map<int,P>* O::Y(){
return a;
}
Error is:
1>O.cpp(76): error : return value type does not match the function
type 1> return b;
1>O.cpp(80): error : return value type does not match the function
type 1> return a;
I'm going crazy trying to debug this....

The code you have posted is valid C++, so the issue must lie elsewhere in your code. I would check the included headers. Here is an example with a valid declaration of P:
#include <unordered_map>
using namespace std;
class P{
public:
int a = 3;
};
class O{
public:
O();
unordered_map<int,P>* X();
unordered_map<int,P>* Y();
private:
unordered_map<int,P>* b;
unordered_map<int,P>* a;
};
O::O(){
a= new unordered_map<int,P>();
b= new unordered_map<int,P>();
}
unordered_map<int,P>* O::X(){
return b;
}
unordered_map<int,P>* O::Y(){
return a;
}
int main(){
O o;
auto map = o.X();
return 0;
}
