Re: [Lemonlauncher-general] Question about SDL backed on /dev/fb

[Josh K. <jo...@sl...>]

Robin,

I've been having trouble with that bit of code actually.  It's not very
portable and seems to cause issues on different platforms/environments.

That said, I don't think I need to check the return value from
SDL_WM_ToggleFullScreen because that function call is ignored for
everything except X11 environment.

In the trunk I have some experimental code which uses the SDL threading
functions to launch the mame process which again has some stability
issues but it might be worth a try.  The code in trunk actually uses
sqlite for the games list so it introduces another dependency and
currently there is no user friendly way to generate your database
(coming very soon).

I will try to setup a system today that uses the framebuffer with SDL and
see if I can't come up with a patch to at least make this work for you.

Regards,
Josh
