*LOL*.

My previous problem with include involved my 
failure to install correctly the C++ libraries.  Since I
am having that same problem with gcc under Debian,
I'll have to go back and check with dselect to see 
if my installation is somehow wrong there, too.

Anyway, now I'm back, hopefully with something marginally less stupid.

I am getting an error message repeated many times
(undefined reference) and I have no idea what it means.
Might this still mean I haven't properly installed yet,
or is there some other problem I'm missing?

Here's my source again, with one correction:


#include <iostream.h>

void main ()
  {
     cout << "Hello, World!\n";
  }
     
And the results:
