Undefined reference to linker error?

[rottmanj]

I have run into an odd situation with linking files in my application. I have written a method that returns data for other methods. When I use this method(with in the same class) I get this error from linking.

Any help with this is greatly appreciated

RetsParse.cpp: undefined reference to `RetsParse::rets_parse_metadata(boost::shared_ptr<librets::RetsSession>)'

Here is my current code base.

.h;

#ifndef RETSPARSE_H_
#define RETSPARSE_H_

#include "librets.h"
#include <iostream>
#include <string>
#include <vector>


class RetsParse
{
public:
	int rets_parse_idx(void);// public method to parse rets data;
	std::vector<std::vector<std::string> > rets_parse_metadata(librets::RetsSessionPtr session); 
};

#endif /*RETSPARSE_H_*/

.cpp

int rets_parse_idx(void){
			
			RetsParse metaAction;
			
			// Define session request
	        librets::RetsSessionPtr session(new librets::RetsSession("URL"));
	        session->Login("USER", "PASS");
	        
	        std::vector<std::vector<std::string> > metaVector = metaAction.rets_parse_metadata(session);
	        
	        std::cout << metaVector.size() << std::endl;
        
	        return 0;

	}

All I see in the code you posted is the function prototype for that function -- where in *.cpp or *.h file is the implementation code?
