Function Error

Hi. I am getting the following error message when I try to call the function I have outlined below. Any one know what the problem might be. Can I write this stand-alone function: Huff* findMinimum(vector<Huff*> v) in this context?

Code:

#include<iostream>
#include<string>
#include<vector>
#include<fstream>
#include<stack>
using namespace std;

struct Huff
{
    Huff();
    int count;
    char ch;
    Huff* left;
    Huff* right;
    Huff* parent;
};

Huff* findMinimum(vector<Huff*>& v);

int main(int argc, char* argv[])
{
	if(argc<2)
	{
	    cout<<"Not enough arguments were provided."<<endl;
		return -1;
	}
    ifstream myFile(argv[1], ios::in);
	if(!myFile.is_open())
	{
	    cout<<"Unknown file specified."<<endl;
		return -1;
	}
	char cz;
    int i;
    vector<Huff*> values;
    while(myFile.get(cz))
    {
        if(cz < 'a' || cz > 'z')
            continue;
        for(i=0; i<values.size(); i++)
        {
            if(values[i]->ch == cz)
            {
                values[i]->count++;
                break;
            }
        }
        if(values.size()==i)
        {
            Huff* h = new Huff;
            h->ch=cz;
            h->count=1;
            values.push_back(h);
        }
     }
     for(i=0; i<values.size(); i++)
         cout<<values[i]->ch<<values[i]->count<<endl;
     findMinimum(values);           /* Trouble with this line */
     return 0;
}

Huff::Huff() : ch(0), count(0) { }

Huff* findMimimum(vector<Huff*>& v)
{
     int index, minCo=v[0]->count;
     char minCh=v[0]->ch;
     index=0;
     for(int i=1; i<v.size(); i++)
     {
         if(v[i]->count < minCo)
         {
             minCo=v[i]->count;
             minCh=v[i]->ch;
             index=i;
         }        
     }
}

Error Message:

Code:

[Warning] In function `main':
[Linker error] undefined reference to `findMinimum(std::vector<Huff*, std::allocator<Huff*> >&)'

Thanks in advance, Steve

Check your spelling:

Code:

Huff* findMinimum(vector<Huff*>& v);
Huff* findMimimum(vector<Huff*>& v)

Ah yes... Optinization can be quite fun.


(Sorry, it's been a long day.)

Thanx Prelude. As always, I really appreciate it.
