I assume that you're using:

#include <iostream.h>


...in your source file?  Have you tried:

#include <iostream>

...remember to "close the gap" in the above directive...

g++ -o hello -I/usr/include/g++-3/ hello.C

Failing that:

// FILENAME: hello.C
using namespace std;
#include <iostream>
int main()
{
  cout << "Hello, World!\n" << endl;
  return 0;
}

Use this compiler invocation:

g++ -o hello hello.C 


...and if that doesn't work, reinstall gcc from your CD containing your
packages.

Take Care.
