Re: [Chicken-users] SDL egg: SDL_GL_SwapBuffers() not implemented?

[Koen Weddepohl]

I managed to download the changes through chicken-setup now.

sdl-gl-swap-buffers works fine, the graphics are displaying.

The functions sdl-gl-set-attribute and sdl-gl-get-attribute are recognized, but when I call sdl-gl-get-attribute it doesn't seem to return the value I've set with sdl-set-attribute. I'm not sure if I'm doing something wrong, I haven't used these two functions before.

Cheers,

I have added sdl-gl-swap-buffers, sdl-gl-set-attribute and sdl-gl-get-attribute,
plus the attribute constants. Unfortunately I can't test it, as the
chicken-3 branch is
currently broken and I don't have a working chicken-3 installation right now.

Perhaps you could give it a try?

 

Of course I'll give it a try, it's the least I can do. (Thanks for the C workaround, by the way.) Should I get it from SVN somewhere? As far as I can tell chicken-setup doesn't download your modified version.
