Function Error Message

[badkaykay]

This is a homework assignment - please do not give me code.

I wrote this program:

#include <iostream>

using namespace std;

int main()  

{ 

string fileName;
ifstream inf;

openFile(inf, fileName);

countL(inf);
	
inf.close();
inf.clear();

return 0 ;
}
//*************************openFile********************************************
//  Name: 		openFile
//  Description: 	opens file
//  Parameters: 	ifstream& inf
//			fileN catches fileName
//  Return: 		none
//****************************************************************************
void openFile(ifstream& inf, string fileN) {
	cout << "Please enter file name:" << endl;
	cin >> fileN;

	inf.open(fileN.c_str());
	
	if (inf.is_open()) 
	    cout << "File is open." << endl;
	
	else {
    		cerr << "File not found - terminating." << endl;
    		abort();
	}
}

This is the error message I am getting:

Undefined first referenced
symbol in file
countL(std::basic_ifstream<char, std::char_traits<char> >&)/var/tmp//ccVWijSX.o
ld: fatal: Symbol referencing errors. No output written to a.out
collect2: ld returned 1 exit status

I see that the error message is telling me to look in the function countL, and I have looked several times to make sure there are no spelling errors, etc., but am still not sure why I am getting this error.

Thanks in advance.

Nevermind - just realized that if a function is passing something, you can't use void. DUH. Will try fixing that and post back.

The declaration of the function

void countL(ifstream&);

and its definition

void countL(ifstream& inf, int charNum, int lineNum)

do not correspond each other.

Thank you.
