Okay, I’ve been using SDL 1.2, but had a few questions about the LGPL
license. So say I make my game, I dynamically link it. Can I give away the
normal game for free, without having to release all my source code? It’s
because as much as I lover open source, I don’t want to release a custom
engine that I spent over a year to write for free.–

You can do that, you can even sell a game using LGPL components as long as they are separate files (dll’s and such).
The GPL is more aggressive, where a closed exe simply using a GPL dll causes the GPL to apply to both the exe and dll, the case of a GPL exe and closed dll similarly has the GPL apply to both.
But the LGPL is designed for this kind of usage, you just can’t static-link SDL 1.2 without applying the LGPL to the exe in the process.On 09/11/2012 06:17 PM, Muhammad Asavir wrote:

It’s worth noting that:
-
SDL2 is under the more permission zlib license. Use this.

Since you have to link statically on iOS (no technical reason: just
because apple are tards), if you use SDL1.2 you WILL be statically
linking with LGPL code, which does mean that your code must be LGPL as
well.~

This is not correct, you only need to provide the linkable object code
of your application upon request, so that it can be linked with a
different version of SDL.

Really? I always assumed that sec’ 4b in the LGPL (the combined work
must be distributed with a copy of this license) meant the combined
work would be under the LGPL too; but hey, I’ve been wrong in the
past.~

You don’t have to give away your source code, as long as you follow a
few (reasonable) rules with the LGPL libraries.
That being said: SDL 2.0 is zlib-licensed, and avoids all that nonsense.
We recommend you use that instead, if you can…but we’ve shipped
multi-million dollar titles with SDL 1.2, so it’s definitely possible
even with the LGPL.
