Sorry for being so dense - I seem to be close, but not quite there yet
Here is my compile command

gdc opengltest.d -o opengltestd -I../SDL -L/sw/lib -Wl,-framework,OpenGL -Wl,-framework,GLUT -lobjc -lSDL -Wl,-framework,Cocoa -lSDLmain
/usr/bin/ld: Undefined symbols:
_SDL_main
collect2: ld returned 1 exit status

I couldn't use your command as I got this error
gdc opengltest.d -o opengltestd -I../SDL -L/sw/lib -Wl,-framework,OpenGL -Wl,-framework,GLUT -lobjc -Wl,-framework,SDL -Wl,-framework,Cocoa -lSDLmain_d
/usr/bin/ld: can't locate framework for: -framework SDL

I've tried to get the OSX SDL framework installed, but to no avail.  The SDL source fails in the ./configure stage (threading unsupported!), and the SDL OSX devel libraries specifically say the framework is not installed & to get it from the sources.

Any help is much appreciated.

Cheers
Brad

You need a special version of the SDLmain, that initializes the D runtime. It also needs to be called from your "main(char[][] args)"

SDL code will come later, just use plain GLUT in the meantime ?

boohoo, sob! :)
Yeah, maybe I'm jumping in just a tad deep.  I'll back off and play with GLUT.  I probably ought to become familiar with the Apple way of doing development also.  All of my linux play apps are SDL based, so hopefully when I get a little smarter they'll all "Just Work" on OSX.

Thanks for the help Anders

Hi again Anders - these examples that you mention, can you please tell me were to find them?

Thanks

They're not updated and online just yet...

They'll be on http://www.algonet.se/~afb/d/

Seems like the next GDC version will be a while,
and so will a coherent download of SDL/GL for Mac.

If you're anxious to get started, see my CVS rep.
(or email me privately, it shouldn't be that hard)

Thanks Anders.  I don't mind waiting :)  I've got plenty to do to figure out how best to use OSX as a development environment.

I played with your CVS tree last night, and managed to get the testgl program working fine.  So I can start playing with my own SDL/D/MacOS stuff now :)
Thanks for the good work.  I take it the SDL stuff you've done is open source, or somesuch?
Also, do you know if it is possible to profile GDC apps with Shark? I've heard a lot about Shark & I think I may play with that next.

It's under the same license as the C headers, i.e. LGPL for SDL

Should be, just that the D name mangling is a little "strange"...
