Thanks, git is kind of a pain on windows though, but i got it compiled and get symbol errors, I'm guessing this is a problem with my setup though. It's nice to see the dsss conf's in there etc.

I am getting these errors with SimpleGL.d does anyone know why?

Seems like you need to link against OpenGL.

So, finally I had the time to spend the whole evening looking this thing up on the internet. I finally ended up with this D newsgroup thread by Ant: http://www.digitalmars.com/d/archives/digitalmars/D/12896.html

It is a discussion about getting DUI (now called GtkD or gtkD?) to compile it's opengl examples on windows with gtkglext.

The problem was that OpenGL on windows needs Windows linkage, and not C linkage... or something like that. Every OpenGL prototype in D has to be defined as extern(Windows) instead of extern(C).

There's only two extern(C)s that will have to be changed in gtkDgl. /srcgl/gtkglc/gl.d approx. line 1176. And /srcgl/gtkglc/glu.d approx. line 293.

But. The solution that was provided on that newsgroup thread didn't work anymore, because it involved abusing the version statement. So after a long while going through these webpages (listed here to illustrate the pain that is involved when reading out-of-date information):
http://dblog.aldacron.net/2007/07/03/derelict-problems-with-dmd-1018/
http://dblog.aldacron.net/2007/07/08/ooops-thats-not-a-feature/
http://www.digitalmars.com/webnews/newsgroups.php?art_group=digitalmars.D&article_id=55391
and finally http://dblog.aldacron.net/2007/07/23/dmd-1019-and-2003/

And there it was - the solution. extern(System). Finally the gtkDgl library works on Windows too. I'll try to see if I can commit from this Windows machine...

And now it's committed.

I couldn't find a place where this fix should go in the wrapper, so either such place should be found, or then we'll have to apply this everytime we wrap srcgl.

(By the way, gtkglext (the C version) still doesn't work with the native quartz OS X GTK+ framework, so you'll have to use X11 if you want OpenGL on Mac OS X. I'll test if X11 works on OS X, later, using Macports.)

when I used gtkD, opengl worked fine on Windows for me with Derelict.
