RE: [GD-General] Re: JPG libs

[<phi...@pl...>]

TiVo provide the patches they made to linux on their web-site somewhere.
The actual TiVo application is entirely closed though (which is completely
legit AFAIAA, given that IANAL ;)

Also note that if you don't ship the LGPL JPEG loading code in your game,
but only use it in your internal conversion tools, you don't have to worry
about this at all.

This rules out static linking.

Don't get me started on LGPL and consoles/ embedded systems ;)

Of course they could've done that. They just would have had to provide the
source. Anyways, Indrema is not a good example as they were Vaporware. BTW,
I don't think it would've been legal for them to ship with LGPLed software
due to the re-link requirement.


> And what about all those embedded apps that use Linux?

I bet if you snail mail them they'll provide you with the Linux source code
they use and I doubt they made many changes to the kernel. Keep in mind
that
binary only kernel modules are possible so they could extend the kernel
without much hassle. They also don't have to provide the source to their
app
running on the OS. That's like saying we had to disclose the source to
Unreal Tournament just because it runs on Linux ;-)

SDL only runs on the PS2s that run Linux.
