John Reimer found that

replacing extern(C) with extern(Windows) on the
DUI OpenGL extension decalrations fixes all the problems
with the OpenGL on DUI.

how do I know which to one use?

DUI is a wrapper to Gtk+ DLLs
DUI openGL is a wrapper to GtkGlExt DLLs.

The interface with the system opengl libs is made through GtkGLExt.

Why should I use extern(C) for Gtk+
and extern(Windows) for GtkGlExt ?
how do I know which to one use?

ignore this I think I got it.
calls to gl* function go directly to the system libraries
the GtkGlExt just enables that (somehow).

now, to use extern(C) and extern(Windows)... how is it?

version(Win32) extern(Windows):
version(linux) extern(C):
glFunctions...
glFunctions...
glFunctions...
glFunctions...
glFunctions...

will it work? I'll give it a try.

PS sorry for sequestring the D group for DUI...

No, that is wrong.
You want to write:

version(Win32) extern(Windows):
else           extern(C):

Since there are other platforms.
Remember: Not Windows != Linux.

thank you.

any reports of DUI working on other platforms are welcome!

I don't think this is a problem to anyone. D needs a good GUI and DUI can provide it :)

Not a problem, however it might be 'nicer' if you had your own group, like on dsource or wherever. I think 'announcements' and 'problems' should be posted here and possibly their resolutions (if applicable to other D projects)

The various posts discussing and solving the problem could be in their own group, but, then again if someone is not interested they can simply ignore the thread can't they.

Perhaps a digitalmars.D.gui NG is a good idea? We have one for the DTL, why not one for gui related discussions it occurs to me that is a large subject area which will only get more and more traffic as D evolves.

I like that idea... GUI programming discussions would likely be popular because that's the next area D needs to advance.  I think the gui question is one of the first queries made by many new people to this group.  D needs one badly. Currently, it seems that DUI is the strongest project in this area.

Ant doesn't seem to like the dsource.org forum format, which is sad.  It would be nice to see that project in subversion there. And I don't like the Yahoo discussion groups one bit. :-(

It would be nice to work something out...

Since it currently has "Win32" and "linux" hardcoded,
it won't compile on platforms other than those two...

Neither dool nor DUI compiles.

Well I dont know if a gui group would get enough traffic for a while (I only
know about DUI atm) but perhaps a more general .D.projects?

My fault! :(
what should I do? just use "else" instead of linux?
