Just wondering if anyone who works for some of the game development
companies has had the chane to port SDL to either PS3 or XB360?

If we did, we would be violating NDAs to post the code, or violating the
LGPL since you wouldn’t be able to recompile it without a devkit.

Actually, not LGPL violation. It says you can link to libraries that are
required to compile anything on a system. Anything in the devkit is covered
under that.

covered
under that.

No, it says:

For an executable, the required form of the “work that uses the
Library” must include any data and utility programs needed for
reproducing the executable from it. However, as a special
exception, the materials to be distributed need not include
anything that is normally distributed (in either source or
binary form) with the major components (compiler, kernel, and so
on) of the operating system on which the executable runs, unless
that component itself accompanies the executable.

Since the devkit is not distributed with the normal operating system
for those machines, that would be a LSDL violation.

…unless I’m missing something.

Hi, Im trying to use WxWidgets with SDL and i was having no problem on doing
that using the example provided by Technoplaza(
http://code.technoplaza.net/wx-sdl/part1/ ).
But When i tried to change the screen color depth from 24 to 32 i messed
everything up. Could Anyone help me convert that example’s screen surface
from 24 to 32 color depth?

Thansk a lot.

Uhm, that interpretation would rule out pretty much everything,
including some modern Un*x platforms. “Normal” operating systems
don’t include any development tools whatsoever.

Then again, though it seems like whoever wrote that part of the LGPL
considers the development tools to be part of the operating system,
that doesn’t mean that part has to come with the standard
distribution of the OS, nor that it has to be available at no extra
cost…

(I could be missing something too, but AFAIK, using SDL on MS Windows
or Mac OS X, just to name two that normally come without dev tools,
doesn’t violate the LGPL.)

You’re going to (at minimum) adapt the pixel code. You’ll need to change
the block where it has #ifdef SDL_BIG_ENDIAN and all that. Look in the SDL
manual for how to place pixels, and you should recognise that code there as
the 24-bit specific version.

Hi,

This there a good way I can tweak the gamma level of OpenGL or should I do
it
just using the SDL gamma functions…?

Yeah, I would interpret that more loosely and consider that when you can
get all the components you need to build the executable freely online,
they are being made sufficiently available and would comply with this
requirement, even if they are not distributed directly with your program
or the target operating system’s base version.

Since these components are freely available for both MacOS and Windows,
assuming your program can be built using the free versions and are not,
say, Visual C++ X specific, I would say that these operating systems are
not a problem.

Of course, I am not a lawyer and I could be misinterpreting this.
