I try to make little class in C++ to test makefile and compilation with
DJGPP. This little class don't link and I don't what is the reason of
this problem. 

	I put in the message C++ code and errors gernerate by compilation.
			Thank you

main.cpp:
#include <iostream.h>

#include "test.h"

int main()
{
  int x,y;

  cout << "entrez une valeur de x: ";
  cin >> x;
  cout << endl;
  
  cout << "entrez une valeur de y: ";
  cin >> y;
  cout << endl;
  
  cout << somme(x,y) << endl;
  
  cout << soust(x,y) << endl;
  return 0;
}

classe test
test.h:
#ifndef test_flag
#define test_flag


class test {

public:
  int somme(int,int);
  int soust(int,int);
  test();

};
#endif test_flag

test.cpp
#include <iostream.h>
#include "test.h"
test::somme(int val1,int val2)
{
  return val1+val2;
}

test::soust(int val1,int val2)
{
  return val1-val2;
}

test::test()
{
}

#fichier makefile pour test
