How to install sdl3 library?

const std = @import("std");

pub const std_options: std.Options = .{
    .log_level = .debug,
};

const c = @cImport({
    @cDefine("SDL_DISABLE_OLD_NAMES", {});
    @cInclude("SDL3/SDL.h");
    @cInclude("SDL3/SDL_revision.h");
    // For programs that provide their own entry points instead of relying on SDL's main function
    // macro magic, 'SDL_MAIN_HANDLED' should be defined before including 'SDL_main.h'.
    @cDefine("SDL_MAIN_HANDLED", {});
    @cInclude("SDL3/SDL_main.h");
});

Ok, I copied the above codes to the main.zig file in src. What should I do now?

22

Try to create a more minimal version of the main function:

Throwing out stuff like audio, drawing of bricks, etc. only keeping the essential skeleton of the function and try to read and understand what the different parts do. I think that would set you up to have a good understanding of how you can build an sdl application.

And then try whether it can be run via zig build run

23

I copied the following into the main.zig file.

const std = @import("std");
const sdl = @cImport(@cInclude("SDL3/SDL.h"));

pub fn main() !void {
    
    if (sdl.SDL_Init(sdl.SDL_INIT_VIDEO) != 0) {
        std.debug.print("SDL Başlatma Hatası: {s}\n", .{sdl.SDL_GetError()});
        return;
    }

   
    const window = sdl.SDL_CreateWindow(
        "Zig SDL3 Örneği",
        640, 480, sdl.SDL_WINDOW_VISIBLE,
    );

    if (window == null) {
        std.debug.print("Pencere oluşturma hatası: {s}\n", .{sdl.SDL_GetError()});
        sdl.SDL_Quit();
        return;
    }

    
    sdl.SDL_Delay(3000);

    
    sdl.SDL_DestroyWindow(window);
    sdl.SDL_Quit();
}

I did a zig build.

did you run the zig fetch command after updating zig

25

What is in your build.zig.zon?

26

zig fetch did not work at all without the update. it worked after the update.

27

The build.zig.zon file is not in the folder I am working in. I don’t know where it is.

28

It is there:

But it should be in the same folder as your build.zig, move it there.

And execute zig build etc. from your project folder.

29

I looked inside the oyun-zig folder. A file named build.zig.zon was not created. There is none. Only a folder named .zig-cache was created. Multiple folders and files were created inside it. I looked at each one one by one. There is no file named build.zig.zon in any of them.

30

Can you re-execute the zig fetch making sure you are inside the folder that contains your build.zig?

The zig init should have created these files.

I think you may have executed zig init in a wrong directory?

31

cd /d D:\oyun-zig

D:\oyun-zig>zig build
I’m doing this.

32

This is your project directory?
Have you ever called zig init in there?

It should have written something like:

info: created build.zig
info: created build.zig.zon
info: created src/main.zig
info: created src/root.zig
info: see `zig build --help` for a menu of options
33

yes. my game is in this folder. it is in the game-zig folder in the d drive. the build and main files are in this folder. i don’t understand where zig init is and what it does.

34

zig init is a command that initializes a new zig project and creates some basic files for a project, similar to how zig build is a command that builds a zig project

35

I read articles about how to create a project. I couldn’t succeed. I asked chatgpt last. He suggested 30-40 steps. I kept getting errors with each suggestion. He kept updating the codes. He made adjustments. But I never succeeded. He gave various errors every time. When I couldn’t solve the problem, he finally told me to create it manually. I created a folder called oyun-zig in the D drive. There is a src folder in it. There is a file called main.zig in it. There is also build.zig in the main directory. He said that creating these folders and files would be enough. I couldn’t do that as you mentioned, creating a project from the console. I got 40 different errors in 40 attempts.

36 
D:\oyun-zig>zig init

gives what output?

37

D:\oyun-zig>zig init
‘D:\oyun-zig’ is not recognized as an internal or external command,
operable program or batch file.

38

No, you need to navigate to the folder and then execute zig init as command, similar to how you ran zig build.

39

cd /d D:\oyun-zig

D:\oyun-zig>zig init
info: preserving already existing file: build.zig
info: created build.zig.zon
info: preserving already existing file: src\main.zig
info: created src\root.zig

40

The files you mentioned have been created.
I did a zig build run again.
the result is below.
D:\oyun-zig>cd /d D:\oyun-zig
