I need some help to sort out why only my old 30 Fedora 2 school boxes will compile:

#include <iostream>
using namespace std;
int main( )
{
cout << "Hello World!!";
}


While my two thin servers running Fedora 3 and 4 serving 100 clients fails to compile... with:

[jim@adminmrc Programming]$ gcc -Wall -o dallasisspecial dallas.cpp

Thanks, Jim

Use g++ to compile C++-programs, gcc is for C-programs.

Your main method expects an Integer as return value too. Don't forget to have a return 0; or something at the end.

Just in case you were wondering

g++ = gcc -lstdc++

Thanks!

OHH!!! Just too many thing going on I guess to think straight.
