前言
说明
参考：
- https://github.com/libsdl-org/SDL
下载路径：
通过 github 的发布页面下载 SDL2 的开发包：https://github.com/libsdl-org/SDL/releases/download/release-2.28.1/SDL2-devel-2.28.1-VC.zip，下载完成后（版本需要一致，或者手动调整路径），将其解压到 Zig 的工程根目录下的libs目录下。

目标
使用 Zig 语言，依赖 SDL2 来启动一个图形化的界面。
build.zig
const std = @import("std");pub fn build(b: *std.Build) void {const target = b.standardTargetOptions(.{});const optimize = b.standardOptimizeOption(.{});const exe = b.addExecutable(.{.name = "demo",.root_source_file = .{ .path = "src/main.zig" },.target = target,.optimize = optimize,});// 这里需要和下载的版本一致const sdl_path = "libs\\SDL2-2.28.1\\";exe.addIncludePath(sdl_path ++ "include");exe.addLibraryPath(sdl_path ++ "lib\\x64");b.installBinFile(sdl_path ++ "lib\\x64\\SDL2.dll", "SDL2.dll");exe.linkSystemLibrary("SDL2");exe.linkLibC();b.installArtifact(exe);const run_cmd = b.addRunArtifact(exe);run_cmd.step.dependOn(b.getInstallStep());const run_step = b.step("run", "Run the app");run_step.dependOn(&run_cmd.step);
}

}fn init() void {if (c.SDL_Init(c.SDL_INIT_EVERYTHING) < 0)@panic("sdl init failed");const center = c.SDL_WINDOWPOS_CENTERED;window = c.SDL_CreateWindow("demo", center, center, //WIDTH, HEIGHT, c.SDL_WINDOW_SHOWN) //orelse @panic("create window failed");renderer = c.SDL_CreateRenderer(window, -1, 0) //orelse @panic("create renderer failed");texture = c.SDL_CreateTexture(renderer, //c.SDL_PIXELFORMAT_RGBA8888, c.SDL_TEXTUREACCESS_STREAMING, //WIDTH, HEIGHT) orelse @panic("create texture failed");
}fn deinit() void {c.SDL_DestroyTexture(texture);c.SDL_DestroyRenderer(renderer);c.SDL_DestroyWindow(window);c.SDL_Quit();
}
启动
zig build run
效果
总结
使用 Zig 语言链接到 SDL2 库，实现了渲染一个窗口。
