Hi there! Thanks so much. The solution sent to me by Marcus is g++ -o mar Array.cc Array_templ_main.cc Sincerely, Ebenezer --- gustavo <gdutra@topsystems.com.uy> wrote:

Hi there!
I am running a SuSE Linux 9.0 machine. These are the header files of the C++ pr0gram I am trying to compile.
Header of the file Array.h
#ifndef _ARRAY_H_ #define _ARRAY_H_
#include <stdio.h>
template <class T> class Array { ... } #endif
Header of the file Array.cc
#include "Array.h"
template <class T> Array<T> &Array<T>::operator=(const Array<T> &other) { ... }
Header of the file Array_templ_Main.cc
#include <iostream.h>
#include "Array.h"
int main() { ... }
The compilation command with GCC is as follows:
ntienjem@njueya:~/examples> gcc -o mar Array.cc Array_templ_main.cc
I got the following errors:

You have to put :
using namespace std;
before your coding, or something like that. I can't recall exactly, because I have not a linux machine near me.. :(
