Description

I get lots of errors when I try to compile my C++ Allegro program.
You are probably declaring the use of a namespace before including Allegro headers. For example: 
      #include <iostream>
      using namespace std;



      #include <allegro.h>


Move the `using' declaration after the `include' directives referring to Allegro headers: 
      #include <iostream>
      #include <allegro.h>



      using namespace std;
