lhelper VS SDL

I have made my own tool to solve this problem:

https://github.com/franko/lhelper

It is currently used by nobody except me but it serves me well.

Its strong points are:

- it works on macOS, Linux and Windows

I agree, for their use case they should have linked to SDL2 as a static library. It was the best option instead of patching the binary with patchelf.

I think many developers don't know about static libraries. For some reason they think they have to use a shared libraries. This is probably due to many tutorial saying something like: download the SDL2 library from there, it is provided as a shared library, here the instructions to use it with Visual Studio.

The way I do is with static libraries, I ship a single executable, all the third-party libraries are linked in as static libraries. The only dynamic libraries the exectuable will use are the standard libraries that are part of the OS.

I do this very easily with the help for lhelper:

https://github.com/franko/lhelper (I am the author)

that has recipes to build many libraries including SDL2. It builds the library on you system using your compiler and your settings. By default it will build static libraries so you don't have to bother distributing additional dynamic libraries.

Wayland works well on the Steam Deck because Valve controls the whole system. Because they have their own Wayland compositor (Gamescope), they're able to implement protocols to work around issues in Wayland without being delayed by the bureaucratic process of getting them approved. Here's an SDL pull request where a graphics developer at Valve discusses how two protocols necessary for good GPU performance haven't been added to Wayland yet so Valve added equivalent protocols to Gamescope as a workaround: https://github.com/libsdl-org/SDL/pull/9345

One thing to note is that the Steam Deck only uses Wayland for its fullscreen gaming mode. When you exit to its desktop mode (meant for running non-Steam software), it switches to X11.

The linked project doesn't use any ObjC files at all. SDL2 has a bunch of Cocoa files[1] so you did use Cocoa even if unknowingly.

Correct. It's explained here:

https://github.com/libsdl-org/SDL/pull/9345#issuecomment-201...

XWayland has special hooks into the compositors that normal wayland clients don't get.

Found about this through the release of SDL 3: https://github.com/libsdl-org/SDL/blob/main/build-scripts/SD...

https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_events.h

If that app ran in a 640x480 mode, memory accesses would be just as fast as the VGA applications 25 years ago, correct?

I think there's a lot more going on than that. Here's SDL's current pixel access code:

We use the code examples throughout the article. The ellipsis characters "...." in the code were added by the author of the article. You can find the source files on the official GitHub of libsdl. In addition, each fragment has a reference to a specific area in the code. By the time this article is published, many errors will have already been fixed thanks to the issues we opened (for example, here and there). However, the links in the examples point exactly to the code you see in this article. Not only do we enjoy teasing developers but we also like making their projects a little bit better!

It's not that difficult, I recently started learning to use graphics APIs myself. OpenGL is for linux, etc., directx for windows and vulkan for all platforms. I read through a bunch of forums yesterday and decided to go for vulkan (here is a link to the sdk) for my next small projects because it can run on all platforms. I would recommend to watch a basic tutorial series (like this one) for the graphics api itself to get an understanding of whats going on. And on top of that I use SDL2 for eventhandling and ImGui for the graphical user interface. Here is a link to a guide for setting up vulkan on your platform in case you would go for it.
