Project overview

This project, undertaken as part of Google Summer of Code 2024, sets out to port SDL2 library for KolibriOS, a free cross-platform multimedia library that implements an interface to graphics, sound and input devices. Considering previous version of the library, SDL 1.2, which was earlier ported for KolibriOS, is no longer maintained, therefore it became a necessity to port the most up-to-date and supported version (i.e. SDL2. Having support for SDL2 (along with its additional libraries) on KolibriOS will not only allow developers to develop new applications using the updated functionality of the library, but also to port a huge number of existing open source programs (mostly emulators and games) from other platforms, because SDL2 is often used to implement frontend/graphics in such applications. This will also allow us to completely deprecate the current SDL1.2 library as we can use a compatibility layer for applications relying on SDL1.x.

In order to see how the progress of this project went, visit this topic of our board.

What was done

Ported SDL2 library (version 2.30.6).
Ported required additional libraries for more compatibility (SDL_image (2.8.2), SDL_mixer (2.8.0) and SDL_ttf (2.22.0)).

What's left to do

Port sdl12-compat in order to deprecate our old SDL library completely.
Add autobuild scripts for the libraries.
Fix potential bugs within audio subsystem.
Port more applications written with SDL2.

Acknowledgement

As always, I want to thank all mentors, developers, and testers who helped with this project, especially @Doczom, @dunkaist, @Burer and @Sweetbread for answering queries on time as well as helping me with problems that I faced.

@arnavbhatt288 hello! It seems like you've really done a great job, but from my point of view you should first have a series of commits or one that loads the original source code and then your edits, otherwise in the future it will be very difficult to distinguish where your problem is and where the problem is with the original library.

Yeah, I already have a repository which I initially made, where there is commit history. It was a mistake to squash them before I made this PR.
