Issue description

I imported raylib in a zig project, following the guide of this tutorial of the reddit of raylib: https://www.reddit.com/r/raylib/comments/17y0gdx/get_raylib_up_and_running_in_just_4_minutes_using/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

Code Example

clone raylib
execute:
zig init-exe

edit build.zig:

const std = @import("std");
const raylibSDK = @import("./raylib/src/build.zig");

// Although this function looks imperative, note that its job is to
// declaratively construct a build graph that will be executed by an external
// runner.
pub fn build(b: *std.Build) void {
    // Standard target options allows the person running `zig build` to choose
    // what target to build for. Here we do not override the defaults, which
    // means any target is allowed, and the default is native. Other options
    // for restricting supported target set are available.
    const target = b.standardTargetOptions(.{});

    // Standard optimization options allow the person running `zig build` to select
    // between Debug, ReleaseSafe, ReleaseFast, and ReleaseSmall. Here we do not
    // set a preferred release mode, allowing the user to decide how to optimize.
    const optimize = b.standardOptimizeOption(.{});

    const raylib = raylibSDK.addRaylib(b, target, optimize, .{});

    const exe = b.addExecutable(.{
        .name = "wolfenstein_3d_zig",
        // In this case the main source file is merely a path, however, in more
        // complicated build scripts, this could be a generated file.
        .root_source_file = .{ .path = "src/main.zig" },
        .target = target,
        .optimize = optimize,
    });

    exe.addIncludePath(.{ .path = "./raylib/src/" });
    exe.linkLibrary(raylib);
    // This declares intent for the executable to be installed into the
    // standard location when the user invokes the "install" step (the default
    // step when running `zig build`).
    b.installArtifact(exe);

    // This *creates* a Run step in the build graph, to be executed when another
    // step is evaluated that depends on it. The next line below will establish
    // such a dependency.
    const run_cmd = b.addRunArtifact(exe);

    // By making the run step depend on the install step, it will be run from the
    // installation directory rather than directly from within the cache directory.
    // This is not necessary, however, if the application depends on other installed
    // files, this ensures they will be present and in the expected location.
    run_cmd.step.dependOn(b.getInstallStep());

    // This allows the user to pass arguments to the application in the build
    // command itself, like this: `zig build run -- arg1 arg2 etc`
    if (b.args) |args| {
        run_cmd.addArgs(args);
    }

    // This creates a build step. It will be visible in the `zig build --help` menu,
    // and can be selected like this: `zig build run`
    // This will evaluate the `run` step rather than the default, which is "install".
    const run_step = b.step("run", "Run the app");
    run_step.dependOn(&run_cmd.step);

    // Creates a step for unit testing. This only builds the test executable
    // but does not run it.
    const unit_tests = b.addTest(.{
        .root_source_file = .{ .path = "src/main.zig" },
        .target = target,
        .optimize = optimize,
    });

    const run_unit_tests = b.addRunArtifact(unit_tests);

    // Similar to creating the run step earlier, this exposes a `test` step to
    // the `zig build --help` menu, providing a way for the user to request
    // running the unit tests.
    const test_step = b.step("test", "Run unit tests");
    test_step.dependOn(&run_unit_tests.step);
}

#3891 introduced a change which breaks building Raylib with Zig version 0.11.0, due to the use of std.process.Child.run (which was renamed from std.process.Child.exec in 0.11.0, see this commit from the Zig repository). An easy fix would be adding a version check and using the correct function name in the waylandGenerate function in src/build.zig.

You can use the master version of Zig instead to temporarily fix this.

For the other error, you probably forgot to add a try before calling raylibSDK.addRaylib():

- const raylib = raylibSDK.addRaylib(b, target, optimize, .{});
+ const raylib = try raylibSDK.addRaylib(b, target, optimize, .{});
