This is a fork of SDL, packaged for Zig (Initially by Andrew Kelley) and in-sync with the latest SDL releases in the main repository.
Unnecessary files have been deleted, and the build system has been replaced with build.zig
We can easily fetch this library using zig fetch, for example:
zig fetch --save https://github.com/pwbh/SDL/archive/refs/tags/release-2.30.3.tar.gzIf another SDL version needed, please see available tags released.
In your build.zig:
const exe = b.addExecutable(.{
.name = "my-project",
.root_source_file = b.path("src/main.zig"),
.target = target,
.optimize = optimize,
});
if (target.result.os.tag == .linux) {
// The SDL package doesn't work for Linux yet, so we rely on system
// packages for now.
exe.linkSystemLibrary("SDL2");
exe.linkLibC();
} else {
const sdl_dep = b.dependency("SDL", .{
.optimize = .ReleaseFast,
.target = target,
});
exe.linkLibrary(sdl_dep.artifact("SDL2"));
}
b.installArtifact(exe);Now lets test it out and see if it creates a window.
Following codesnippet should create a window that can be exited.
const c = @cImport({
@cInclude("SDL2/SDL.h");
});
pub fn main() !void {
if (c.SDL_Init(c.SDL_INIT_VIDEO) != 0) {
c.SDL_Log("Unable to initialize SDL: %s", c.SDL_GetError());
return error.SDLInitializationFailed;
}
defer c.SDL_Quit();
const screen = c.SDL_CreateWindow("My Game Window", c.SDL_WINDOWPOS_UNDEFINED, c.SDL_WINDOWPOS_UNDEFINED, 400, 140, c.SDL_WINDOW_OPENGL) orelse
{
c.SDL_Log("Unable to create window: %s", c.SDL_GetError());
return error.SDLInitializationFailed;
};
defer c.SDL_DestroyWindow(screen);
const renderer = c.SDL_CreateRenderer(screen, -1, 0) orelse {
c.SDL_Log("Unable to create renderer: %s", c.SDL_GetError());
return error.SDLInitializationFailed;
};
defer c.SDL_DestroyRenderer(renderer);
var quit = false;
while (!quit) {
var event: c.SDL_Event = undefined;
while (c.SDL_PollEvent(&event) != 0) {
switch (event.type) {
c.SDL_QUIT => {
quit = true;
},
else => {},
}
}
_ = c.SDL_RenderClear(renderer);
c.SDL_RenderPresent(renderer);
c.SDL_Delay(10);
}
