and also my build.zig is shown below

```auto
const std = @import("std");

// Learn more about this file here: https://ziglang.org/learn/build-system
pub fn build(b: *std.Build) void {
    const exe = b.addExecutable(.{
        .name = "main",
        .root_source_file = b.path("src/main.zig"),
        .target = b.standardTargetOptions(.{}),
        .optimize = b.standardOptimizeOption(.{}),
    });
    exe.linkLibC();
    exe.linkSystemLibrary("readline");

    // 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);

    // 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);

    // 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);
    }
}

Hey @Chaituvarma-109, could you confirm if you’re running Zig v0.14 locally?

It looks like the repo is currently set up with v0.13:

 ![image](https://canada1.discourse-cdn.com/flex003/uploads/codecrafters/original/2X/3/3cdeeb2677b9fda6f9caad98421b822a2b3d3157.png)

Once you confirm, I can upgrade the buildpack for your repo to v0.14, which should resolve the issue.

@Chaituvarma-109 I’ve upgraded the buildpack version for your repo to v0.14 and pushed a new commit.

You can run `git pull` to start using it. Let me know if you run into any issues!

You’re not limited to just **readline**. You’re welcome to use any alternatives that you prefer.
