title: How to make OpenGL apps in 64-bit Windows?
body: <p>My project compiles, link and run in xp32 then I tried to cross compile it to x64 and I came across a lot of questions:</p>
  
  <ol>
  <li>There's no native x64 instalable OpenGL SDK so I link against what?</li>
  <li>I saw someone saying that x64 apps use 32bits opengl dll. I tryied to run my compiled 64-bits app in a xp64 with drivers to my video card (radeon 4850), the same I use on xp32 and I got that typical error "bla bla bla, maybe reinstalling you application will resolve the problem"</li>
  <li>If I use video card drivers how to keep it working with another Cards, should I build a version for each? (no sense). Should I load an available library dinamicaly? (same no sense) </li>
  <li>Which is the reference implementation for x64? where do I find its libs to link against?</li>
  </ol>
  
  <p>I'm really lost on that matter. I did a lot of searchs and found nothing that helped me understant till the momment. </p>
  
  <p>So, what is the path? What I want to know to make native x64 OpenGL apps?</p>
